Dubia Roach Gut Loading Guide

Choosing Dubia roaches as feeders for reptiles, amphibians, arachnids, and other insectivores is a wise thing to do. They’re chock-full of nutrition, they beat other insects on many nutrition-related metrics, and much more. However, despite their superior nutrition, we still recommend gut loading Dubia roaches.

This is because some health issues have more to do with captivity than feeder insect deficiency. These include less natural sunlight, lack of dietary diversity, and less physical activity compared to wild animals. All too often, these deficiencies lead to stress, general decline, and acute illness in captive insectivores.

Fortunately, you can address many of these issues with gut loading. This guide discusses what, why, and how to gut load Dubia roaches.

  • Conclusion

Gut loading feeder insects is a common practice among those who keep insectivores. Whether we do it for more calcium, vitamin C, or other important nutrients, we know it’s something we need to do for the health of our animals.

Gut loading Dubia roaches requires very little effort. And for such little effort, it reaps huge rewards. It’s also easy. All you need is the right information, some Dubia roach gut load, Dubia roaches of course, and a desire to make it happen.

What is gut loading?

Gut loading is the practice of providing nutrients to insects not for their benefit, but for the benefit the animals that eat them.

The process is simple. First, feeder insects are gut loaded. This means they are fed something that has nutrients thought to be beneficial for the insectivore. It can be “healthy” foods with lots of vitamin C, for example. Or, it can be an actual gutload, which is a substance containing many nutrients that is made for this purpose.

Then, after consuming the substance, the insects are fed to the animal.

General gut loading concepts

Gut loading is an indirect way to get primary nutrition to an insectivore. Instead of eating a particular plant, for example, the insectivore eats an insect that has eaten the plant. The nutritional value of a gut loaded insect is the insect itself, plus whatever is inside its stomach and intestines. The goal is to give the insects healthy fare that will benefit the animals that eat them. This can be specific vitamins and minerals, general macro or micronutrients, or any combination of the two.

Gut loading is for the insectivore, not the insect

It’s important to note that gut loading is done exclusively for the benefit of the insectivore, without regard for the health of the insect. The nutrients given the insect are meant to nourish the insectivore, not the insect. The purpose of gut loading is to get (often plant-based) food and its nutrients into an (often carnivorous) animal to satisfy that animal’s nutritional needs. Therefore, a gut load is anything good for the insectivore, even if it is bad for the insect itself.

Because of this, gut loading is often a short-run proposition for the insect. In cases where a gut load does not satisfy its nutritional needs, the insect will make up the deficit with its own reserves. This reduces its nutritional value as a feeder, so ideally you want to start with healthy insect stock and gut load them for a short time before feeding them off.

The exception to this rule is when the gut load material happens to be healthy for the insect. In this case, insects can be kept longer without compromising their nutritional value.

Is gut loading the same as feeding the roaches good food?

We hear this question a lot. These two things are often very similar. The distinction between gut loading and regular feeding is intent and timing.

Regarding intent: “Gut loading” means giving Dubia roaches food intended not for them but for the animals that eat them. The distinction between gut loading and regular feeding is at it’s greatest when you feed the roaches something that is actually bad for them but good for the insectivore. Or, something that is bad for them in the quantity you give them, but good for the insectivore. A good example is calcium. Another is vitamin A.

Regarding timing: Traditionally, “gut loading” means feeding an insect a lot of stuff that is good for the insectivore shortly before they are fed off. The implication here is that the food in the insect’s belly (the gutload) ends up in the belly of the insectivore largely undigested. So in a sense, the gut load is meant for the insectivore, but it’s fed to the insect. This is done mainly because carnivorous animals don’t eat plants, and plants are the things with the good stuff we want to gutload.

This is how it works in the wild. Insects eat plants, then insectivores eat the insects that ate the plants. These insects often have undigested plant matter in their guts, and this is how nutrition passes from insect to insectivore. This is gut loading. This is what we want to imitate in captivity.

So the answer is that gut loading and feeding insects healthy foods are similar. There is often overlap between the two. When we refer to gut loading Dubia roaches, we are talking about feeding them healthy food specifically for the benefit of the animals that eat them, without regard for the health of the insect.

How long to gut load?

Gut loading is usually done hours or days before feeding off the insects. However, most feeder insects digest their food within 24 hours, so the practical value of their gutload is measured by what they consumed the previous day. However, as you will see, Dubia roaches are different. They have a unique digestive system that extends their effective gut-loading time to as many as three days. This has added benefits for the animals that eat them.

Making up nutritional gaps

With respect to the balance of intrinsic (the insect) versus extrinsic (what it ate) nutritional value for the insectivore, gut loading is supplemental. It’s a way to get additional nutrients to an animal, or to supply nutrients that may be absent from its diet. In either case, the insect is still the primary nutrition source. The food in its stomach is secondary. However, both are important. Perhaps not equally so, but there’s no need to choose one over the other. Dubia roaches allow you to select both to a greater degree than other feeder insects.

Why gut load Dubia roaches?

Proper nutrition is essential for keeping captive reptiles healthy. The same goes for amphibians, arachnids, and other insectivores. Providing feeder insects with nutrition appropriate to the animals that will eat them can maintain good health, and it can help bring sick or stressed animals back to good health. The key to good feeder nutrition is (a) choosing a nutritious feeder then (b) loading its gut with healthy foods.

Being the most nutritious feeder insect doesn’t mean having all the nourishment your animals will ever need. It would be nice if this were true, but it’s not. Animal nutrition is complicated, and so is the interplay between nutrition, diet, and health. As it stands, there is no single insect that meets all the dietary needs of every insectivore. Dubia roaches come closest to this ideal, but there is still room for improvement via nutritional enhancement (i.e. gut loading).

Calcium is a good example. Like all insects, the Dubia roach doesn’t have a skeleton, and its exoskeleton doesn’t have any calcium. Dubia roaches provide animals with dietary calcium, but it comes from their body, not their exoskeleton. And importantly, the calcium from Dubia roaches is not enough to grow and maintain an insectivore’s skeleton (assuming it has one).

So then how do insectivores get enough calcium in the wild? Part of the answer is that nature gut loads. Calcium comes from the ground. It is abundant in soil, compost, and vegetation – all the things insects love to eat. Many or most of the insects eaten in the wild themselves ate in the previous 24 hours, and this is how insectivores get their calcium. From the guts of the insects they eat. It’s also how they get other minerals and vitamins. In a sense, insects come gut loaded in nature.

Lack of dietary diversity

In addition to eating a bug and its lunch, wild animals tend to eat a diverse diet. The variety of prey they encounter in nature is far greater than what is practical in captivity. This is another way animals in the wild meet their nutritional needs. Dietary diversity helps keep them healthy. The dietary monotony of captivity, on the other hand, is a reason to gut load.

And many animal owners do. As a group, we put significant effort into replicating our animal’s native habitat. But the natural diet of exotic animals is often difficult to imitate. It’s just not feasible to provide an insect buffet of ten or twenty different species. While replicating a captive insectivore’s natural diet may not be doable for most people, feeding them gut loaded Dubia roaches is. Dietary diversity can be replicated by (1) choosing Dubia roaches as a primary feeder, (2) supplementing with occasional treats for variety, and (3) gut loading.

Gut loading: what experts suggest

In case you need more convincing, Merck veterinary manuals considers nutritional supplementation a “must” for amphibians (external link), and “required” for reptiles (external link). They point to two forms of supplementation: gut loading and dusting. We agree that dusting is beneficial, but dusting is different from gut loading.

Superior Dubia roach gut-loadability

Another reason to gut load Dubia roaches is their inherent gut-loadability. First, they can eat a tremendous amount of food. The difference between a hungry Dubia roach that hasn’t eaten in a while and one that’s full can be as much as three times its body weight. This is a huge opportunity to load them up with lots of fresh, whole foods to increase their nutritional value.

In addition to a massive storage ability, Dubia roaches are also unique in their capacity to keep food in their belly for up to three days. The volume of matter in their guts may be greater than that of other gut loaded insects on a per-weight basis, and what’s in there will be in various states of digestion.

The first point is important because more gut load means more nutrition. However, the second part is also very interesting and may be significant. The nutritional profile of plant matter differs according to its stage of digestion. Different digestive stages provide different nutrients for any given food over time. There isn’t much research on this, but the idea that insectivores need insects to do some of their food processing to get certain nutrients is something scientists are looking into.

Dubia roaches: unique digestion abilities

This leads to yet another reason to gut load Dubia roaches, which is that they can digest plant matter other feeder insects can’t. Roaches digest plant fibers with the help of specialized bacteria in their guts. This means roaches have access to nutrients carnivorous animals on their own don’t (external link). The only way insectivores can get these nutrients is to eat the roach.

It’s reasonable to think at least some nutrients unlocked by roaches are required by insectivores for good health. How much of these nutrients is unknown, but the idea goes back to evolution and dietary diversity. The inter-dependency among predator and prey makes sense, and it’s a common relationship found throughout nature.

The bottom line is that captive insectivores living outside their natural habitat eating insects other than their natural prey need nutritional supplementation to achieve full health. Dubia roaches are super nutritious, but we still advise supplementation. Gut loading Dubia roaches with nutrient dense plant foods or a formal gut load should be done at least occasionally, but preferably often.

How to gut load dubia roaches

Gut loading Dubia roaches is easy. At its most basic level, you could simply throw in some fruits or vegetables and call it done. This is one way to go, and your animals will likely be better off for having done it. However, this approach leaves something on the table. You could do more, and your animals might be healthier if you did. You can avoid this missed opportunity by learning from our experience below.

The following are some basic steps to gut loading. They’re based on our experience and are fairly self-explanatory. You will find general guidelines, specific reasons, and some things that we think are good to know.

Decide what you want to accomplish

First, decide what you want to accomplish and why. The practice of gut loading can be divided into two categories. We call them “specific” and “general”. They overlap somewhat but are separated by how an insect is gut loaded, with what (to some degree), and for what purpose.

Strategy 1: general gut loading

General gut loading involves feeding the roaches foods considered “generally healthy” for the target animal. These might include any number of fruits or vegetables containing a variety of essential macro and micronutrients. Examples include carotenoids, carbohydrates, calcium, and vitamin C. These are all nutrients animals need in some quantity, depending on the species.

The goal of general gut loading is the reliable, long-term provision of basic nutrition via healthy feeder insects (the roach) supplemented with whole plant foods (the gut load). Examples include any number of whole grains, vegetables, and fruits. Dubia roaches enjoy apples, oranges, and bananas. They also really like sweet potatoes, beets, and carrots. These foods are excellent general gut loads because they contain basic nutrients animals need. They also happen to be available in most supermarkets throughout the year.

The key is to find something that works for you and your animals, then provide it consistently. This might include a single food or two, or you might mix it up from time to time. How you proceed is entirely up to you. The key words here are “healthy” and “reliable”.

Consider organic produce

At this point it’s worth mentioning that organic foods – particularly fruits and vegetables – are the safest choice for gut loading. Pesticide exposure from conventional produce may not kill an animal, but it probably causes at least some degree of metabolic stress. How much stress and what impact that has on the animal may depend on the species, its health, and other factors specific to your unique situation. This goes to the purpose of gut loading, which is nutritional support. You don’t want to defeat that purpose.

Whether or not you end up going organic is your choice, but we wanted to let you know it’s an option and why it might matter.

Strategy 2: specific gut loading

The alternative to general gut loading is specific or targeted gut loading. The two are very similar. For example, general and specific gut loading often include the same foods. However, they differ in important ways. Intent and approach are probably the most obvious.

Specific gut loading involves feeding the roaches foods that contain certain nutrients for a specific reason. One example could be carotenoids (for vitamin A) to address an animal’s existing eye issue. Or it could be that a particular species is prone to developing eye problems, so a gut load can target carotenoids to help prevent them from developing.

Any nutrient or micronutrient can be targeted in specific gut loading. It could be carotenes for vitamin A, vitamin C, or any other vitamin. It could be foods with high iron or calcium, or foods with low iron or calcium. Specific gut loading is for animals with a nutritional deficiency, animals that may be prone to a particular deficiency due to species or situation, or animals that may simply benefit from an additional boost (or reduction) of one nutrient or another.

Food selection

After deciding what you’re doing and why, the next step is figuring out what foods to use. Dubia roaches aren’t particularly finicky eaters, but they do have preferences. To maximize your efforts, look for foods that achieve your objective, that the roaches also like. Food they only mildly enjoy won’t be a “failure”, but like haphazard gut loading, they may leave something on the table. The effort won’t be as successful as one where the roaches love a food so much they fill their bellies to capacity. This is obviously what you want them to do.

Foods that are good for specific gut loading that Dubia roaches have a taste for include apples, bananas, beets, broccoli, carrots, oranges, squash, sweet potato, various cooked grains like oats, wheat, and rice, and zucchini.

Food issues: Gut load palatability

With this approach, you may run into a situation where the roaches don’t like what you’ve fed them. Don’t worry if this happens. There’s a trick to getting Dubia roaches to eat a gut load they don’t like.

The trick is to mix it with some fruit, sugar or bread. Dubia roaches love sugar. They also like yeast. While neither sugar nor yeast will contribute much to the quality of the gut load, they serve a purpose in this case. Just use them sparingly. It doesn’t take much sugar to get Dubia roaches interested. You can also try both sugar and yeast. Let the mix sit in a warm, dark place for an hour or so and the yeast will consume some of the sugar. Table sugar works, but whole fruit is probably a better option because it contains vitamins, minerals, and fiber. In our experience, fruits can be added to a gut load in any amount without negative consequences. However, we do suggest adding citrus fruits sparingly because some animals seem to have issues with it.

Whether or not citrus is part of your gutloading depends on the animals that will ultimately consume the insects. We’ve seen and heard that some reptiles, for example, are not at all impacted by citrus fruit while others are. That might be something to consider researching with your particular situation in mind.

Gut load cautions

While almost everything is fair game, there are a few foods that you should gut load with caution, sparingly, or not at all. These recommendations are based on our own observations. While we’re confident in what we’ve seen, your mileage may vary.

Beans: bad for insectivores

Don’t gut load with beans. We’ve noticed that beans may have potentially negative effects on both roaches and the animals that eat them. Beans are protein-rich, full of nutrition, and healthy for humans, but they may not be quite as healthy for insects or insectivores. We don’t have more information on this. It’s just something we’ve noticed. Maybe it’s the lectins, which are part of a plant’s natural protection against being eaten. Humans have evolved ways of dealing with lectins, but perhaps some insects and insectivorous animals have not. Whatever the case, we suggest avoiding beans.

Be careful with citrus

Don’t gut load with too much citrus fruits. How much is “too much” depends on the situation. Dubia roaches are not sensitive to citrus, but some animals are. Be aware of this if you gut load with oranges, grapefruit, or other citrus fruits. Tomato products too. One solution may be to wait at least a day before feeding off roaches loaded with citrus. If your animals lose their appetite after feeding on citrus-stuffed roaches, or if they start losing interest in Dubia roaches altogether, it could be a problem.

Avoid gut loading with meat

Don’t gut load with meat. Dubia roaches will eat meat, but it’s really not their thing. They prefer plants. As gut load, meat may not negatively affect your animals in a direct or significant way, but it sort of defeats the purpose of gut loading. Gut loading should provide nutrients your animals otherwise wouldn’t get from the Dubia roaches themselves. They are already getting lots of protein from the Dubia roaches. What’s missing – and what they need from you – are nutrients they don’t get from the roaches. This will be things found in the plants Dubia roaches eat, such as vitamin C, plant phenols, fiber, etc.

We also recommend avoiding dog food, cat food, or similar processed animal feed. While probably not the worst thing in the world, we maintain the same caution for pet food as with meat. Yes, pet foods have “high protein”, but so do Dubia roaches. You already have that covered. Pet foods also tend to contain grains like rice, wheat, and corn. These aren’t usual gut load foods. A pet food gut load is high in protein and fat, and low in the nutrients you should be targeting. The more whole (unprocessed), natural (unprocessed), plant food (not meat), the better. Pet foods can be used as a gut load if you insist, but we think they leave something on the table.

Keep it fresh

Don’t gut load anything rotten. This probably goes without saying. Dubia roaches can and will eat almost anything, but this doesn’t mean they should. And your animal probably can’t eat anything and everything, so be mindful of the quality of the gut load. Unless of course you’re feeding a monitor lizard, in which case it doesn’t matter and you can do whatever you want.

Save supplements for dusting

Don’t gut load with pure calcium or vitamin powders. These are meant to be dusted on insects before feeding them off. There’s no guarantee Dubia roaches will eat pure calcium, for example. In fact, it’s reasonable to believe that they may avoid it altogether. Cockroaches have a known ability to eat preferentially, so it’s conceivable that they might “eat around” something like pure calcium or synthetic vitamins.

Also consider that just like too little of any one nutrient can be bad for an animal, so can too much. Examples include calcium, iron, and vitamin A.

In conclusion…

Gut loading should be fun. It involves some measure of creativity, you get to see the result of your efforts, and it’s an easy way to improve the health of your animals. In a sense, it’s a way to positively interact with them. It has the very real potential to improve their lives, which is worthwhile in and of itself. And of course, anything that improves their lives increases your enjoyment of them.

While we suggest following these basic guidelines and gut loading your Dubia roaches, this area is ripe for experimentation. We encourage you to try new things. However, a word of caution: It’s best to stay within the boundaries we’ve described above. Of course, each animal and situation is different, and what works in one case may not be right in another. Start with the basics, find what works for you and your animal, then branch out and test new ideas and foods from there.

As always, we’re interested to know people are doing with their gut loads. Let us know if you find something that works particularly well for your animals, or your roaches!

    Can I feed the roaches the same gut load “green jello” stuff I feed my crickets? Would this give them all the nutrients they need without additional fresh food?

      Commercial gut load products typically have high amounts of certain nutrients that are deficient in the diet of common captive insectivores. They are like a vitamin pill versus a balanced diet. They are meant to be supplemental for the animal feeding on the insect rather than a complete diet for the insect. If the label says it can be used as a complete insect diet, then maybe you can try that, but otherwise we would recommend against it.

    I just bought some tiny Dubias to try with my baby crested geckos. Is there a certain period of time to gut load before feeding to my gecks?

    Reply to Samantha
    • DRD says

      April 20, 2019 at 9:46 pm

      Good question. The value of gut loading is typically the gut load itself, so you can feed insects to your geckos as soon as they eat the gut load.

      However, Dubia roaches have a unique digestive trait, which is that they digest food for as many as three days before eliminating it. This means that eating Dubia roaches that were gutloaded 2 or 3 days earlier could have added benefits for your geckos.

      Not much is known about the nutrient composition of two and three day-old gut load in a roach’s digestive tract because it hasn’t really been studied. However, researchers think Dubia roach digestion may unlock nutrients not otherwise available to insectivores, or transform some nutrients into others that the animal would not otherwise get or get in smaller amounts. This happens because Dubia roaches have special bacteria in their guts that other insects don’t, and these bacteria process nutrients in ways other insects can’t.

      If you’re interested in this, you could make a gut load available to your roaches now and start feeding them off to your geckos fairly soon – basically as soon as they’ve eaten some – but then you can keep feeding the roaches off over the course of days as they digest the gut load and produce some of those substances experts think may be so beneficial.

      Sure. It’s possible.

      The two main issues are spoilage and cleaner crew proliferation, but these aren’t relevant to every situation. Most things go bad quickly in a Dubia breeding environment, but feeders don’t need the same dark, humid, warm conditions so their food may last longer. Cleaner crews may also use the occasion to proliferate quickly, but not everyone has cleaner crews.

      Giving your Dubia roaches a constant supply of food should work fine if neither of the two issues above apply. If they do apply, you can give your Dubia a bunch of food and keep an eye on it and the cleaner crews, then make adjustments as necessary.

      For tarantulas, you can gut load Dubia roaches with fruits and vegetables. A lot of people gut load with fish flakes or another protein source, but I’m not sure this is necessary. Dubia roaches are already a high protein feeder insect, so doubling up on protein may not be necessary. I would be most concerned about getting vitamins and minerals into Dubia roaches when gut loading for tarantulas, but be sure to avoid extra calcium. Tarantulas don’t have skeletons and too much calcium can cause problems with molting.

      Generally, you want to gut load Dubia with the nutrients reptiles, including bearded dragons, may lack or need in larger quantities in captivity. Because bearded dragons eat vegetation, you can relax a little on gut loading roaches, crickets, and other feeder insects. Bearded dragons have specific needs and cautions when it comes to greens, so the rule of thumb here is that you shouldn’t gut load Dubia roaches with anything you wouldn’t want your bearded dragon to eat.

    I guess I still don’t understand the difference between gut loading and just feeding them daily. My dubias always have access to the dry roach food and are fed daily a variety of fruits and veggies. Is this considered gut loading? It also seems like they really don’t eat that much (the feeders and the adults) I will set a dish with a few greens or sliced potato even a baby carrot and when I check on it the next day, it doesn’t look much different. Thank you!

      When you feed Dubia roaches, you give them foods to help them grow big and strong. When you gut load Dubia roaches, you feed them food that will help the animal that eats them grow big and strong. The two may be the same, but sometimes they are not.

      Think of it like this: Gut loading is feeding, but feeding is not necessarily gut loading. The difference is intent.

      An animal’s primary source of nutrition when eating a Dubia roach is the roach itself. What’s in its stomach is extra. It’s secondary. Gut loading makes sure that “extra” is also something healthy for the animal – maybe something it needs more of because captivity demands more of it, or provides less of it.

      In your example, you feed your Dubia fruits and vegetables. These are nutritious for both the roaches and the animals that eat them. You could consider this gut loading if you wanted. You also feed your roaches potatoes – let’s assume white potatoes. While perfectly good roach food, white potatoes don’t add anything special to your animal’s diet, so it’s not really gut loading. However, if your vet told you that your chameleon has eye problems and recommended adding more caretenoids to its diet, feeding sweet potatoes and carrots to your Dubia roaches would definitely be gut loading (because both foods contain caretenoids).

    Do Dubia’s breathe through their skin? Every time I try to “dust” crickets, I kill them. I’ve stopped using the dust because I’m too deadly with it.

    Also, the Dubia’s I have purchased from a major retailer don’t seem to eat. I put food in for them and it dries up (carrots, cabbage). I don’t think they’ve eaten for weeks!

      Dubia and other roaches breathe through spiracles, which are small valves located along their body on the lower side, next to the belly. They can actually survive for days or even weeks without their head because they don’t need it to breathe! I’ve never heard of Dubia roaches suffocating from dusting, and I suspect that’s something unique to crickets and maybe other small feeder insects.

      Customers report that our roaches eat aggressively after they arrive. There may be exceptions for exposure to very cold temperatures or other stressors in transit, and in these cases the roaches may need more time to recover. Generally speaking though, they should eat. If they aren’t, there may be a problem.

    I gut load dubia roaches with a commercial High Calcium cricket food – the only one my vet said has been proven to provide calcium through gut-loading. In fact he recommends against dusting with powders because of its inexact measurements. He said you could easily dust toxic levels of calcium over time or not give them enough calcium. What is the best way you guys have found to specifically gut-load for calcium?

      Calcium is a unique case at least in part because of the measurement issues you mention. We’ve had success dusting with calcium/vitamin D powder every other feeding. Ironically (assuming you believe your veterinarian), we do it because measurement is easier and probably more accurate with the powder/dusting versus gut loading. Dusting allows you to see how much you use over time (by looking at how much of the container you’ve used), and thus an understanding of how much you’re feeding your animals. If you were to feed the powder (or high calcium foods) as gut load to feeder insects, you would get a worse sense of how much they eat because they may not have actually consumed it. Dubia roaches, for example, can self-select for certain nutrients, and I think they’re less likely to eat a mineral if they can avoid it. Other insects can do this too, to varying degrees.

    Are crushed peanuts and walnuts ok to add to the Dubai roach food? I am feeding American Toads.

      Not being familiar with toads, we can only comment on the Dubia roach side of the equation. In our experience, walnuts are OK. Peanuts may be OK, but we would suggest caution because they are known to cause problems in humans, including a fungus called aflatoxin, which could conceivably be harmful to Dubia roaches. You might want to do a bit of research if you want to feed peanut and walnut gut-loaded Dubia roaches to your American Toads. If you decide to proceed, maybe start slow and see how it goes.

Update: Had some epic COVID/lockdown issues. Sorry!! I am back now and working through outstanding orders. When I get through them all I will relist out of stock items, which will allow updates to payment information and subscription resumption. When I get caught up I'll write about what happened.
