Do you have Dubia roach questions? We have answers. Our Dubia roach FAQ contains topics we haven’t covered elsewhere on our site (i.e. in guides, posts, or product pages), or a quick answer and a link to more information for questions we’ve already addressed. If you don’t find what you’re looking for, please let us know in the comments below!
Is there anything I shouldn’t feed Dubia roaches?
As breeders, no. As feeders, don’t feed them anything you don’t want your animals to consume. Citrus fruits, for example, can cause temporary gastric distress in some reptiles. Excess calcium may not be good for tarantulas. As with any feeder insect, the end consumer should be your focus.
Do Dubia roaches require fresh fruits and vegetables?
No. Dubia roaches can survive on a well-formulated dry food alone. However, you might consider adding fresh fruits and vegetables to their diet for the following reasons: Roaches like them, they contain nutrients dry foods don’t, and they appear to boost productivity.
What is the best food for Dubia roaches?
The answer is more complicated than the question suggests. There is no one food that Dubia roaches do better on than others. Give them a healthy diet with plenty of the nutrients they need at different growth stages. The trick is knowing what nutrients they need at which time. Without going into the details, their general nutritional needs can be met by providing a variety of grains, fruits, and vegetables. For feeders, try to include foods that contain the nutrients you want your animals to consume.
What do Dubia roaches eat in the wild?
Their natural foods include dead leaves and decaying plant material, lots of secondary bacteria, fungi, fruits, roots, and dead insects or mammals they may come across. Occasionally, they even eat each other.
What are Dubia roach’s favorite foods?
Some of their favorite foods include include apples, bananas, beets, carrots, oats, oranges, squash, and sweet potato.
How can I increase Dubia roach reproduction?
Temperature is number one, followed by promoting health via proper nutrition and environment. We cover this topic in our in-depth Dubia roach breeding guide.
Should I give Dubia roaches vitamin and mineral supplements?
We wouldn’t recommend it unless you are gut loading them for your animals. This is a tricky topic. For example, beta-carotene is just one of 600 identified carotenoids in plants, and science does not know how they all interact with respect to nutrition and health. Supplements may make sense in some areas but not others, and for some animals more than others. Different classes of animals have different nutritional needs and concerns so there is no one-size-fits-all answer.
How much roach chow do I need?
Very roughly: 5,000 breeding adult Dubia will eat about one cup of roach chow per day if offered no other food. That means 1,000 roaches can eat about six cups of chow a month and 100 roaches can eat one cup every two months. Of course, this all depends on their environmental conditions. In particular, temperature and access to other foods.
How long do Dubia roaches live?
Females live around two years and males around 18 months under ideal conditions. In captivity, Dubia roach longevity seems related to temperature and food availability. Maximum lifespan appears to occur when they are kept around 80ºF and not provided access to constant food.
What happens if Dubia roaches escape in my house?
It depends where you live. In most places, they will die in a number of days or weeks. Dubia roaches are nothing like German or American cockroaches. They require a tropical climate to grow and reproduce. Even if they were to colonize, they are not destructive, but they cannot colonize in most places in the U.S. The possible exceptions are southern Florida and Hawaii, but these states restrict the importation of Dubia roaches.
Do I ever have to separate adults from nymphs?
Yes, but only to alleviate overcrowding. Dubia are social roaches that naturally live together in large numbers. The only time you may need to separate nymphs from adults is if growing nymphs begin to crowd out the adults.
Can you tell male and female Dubia roaches apart before they’re adults?
Yes, you can tell them apart by turning them upside down and counting the abdominal segments, starting at the hind legs. Female nymphs have five while males have six – the last of which is typically narrow and pointy compared to the female.
What if I buy Dubia roaches and they breed out of control?
They actually reproduce rather slowly, but if you’re concerned we will probably be willing to take them off your hands. If your colony is out of control and you want help, contact us.
Will Dubia roaches hurt or bother my animal if I let them loose in its cage?
Probably not. Dubia roaches don’t bite and are generally mild-mannered, though adult males tend to be somewhat hyperactive. Dubia mostly wander reptile and other cages in search of dark, warm places to hide. If you are concerned, you can contain them in a feeding dish.
Will Dubia roaches eat the plants in my animal’s cage?
It’s unlikely. While they eat a lot of things, house plants aren’t usually among them. We can’t say they will never gnaw at plants, but we haven’t seen it happen.
Can I feed my animals only Dubia roaches?
While Dubia roaches are healthy feeders, insectivores do best on a diet containing at least some variation. Try to mix it up every once in a while if you can.
Why are Dubia roaches different colors?
Color variation is probably caused by some combination of genetic variation, age, diet, and environment. Individual Dubia roaches can vary substantially even within the same colony.
Why are some Dubia roaches flat while others are more round?
Dubia roaches that haven’t eaten in a while will appear relatively flat. Ones that are “rounder” have food in their guts. Flat ones will regain a fuller appearance when they eat or drink.
Can Dubia roaches live without their heads?
Yes, if you call a headless existence living. Because roaches don’t breathe through their mouths, and because they have an open circulatory system, they can survive for a few days without their heads. However, they are unable to eat, and they soon die.
Could I be allergic to Dubia roaches?
Yes, it’s possible. Roach dust like grass, pollen, and mold, can trigger an allergic reaction in some people. Cockroach allergies (external link) are not common but they do occur.
Are Dubia roaches legal in Florida?
Yes, with a permit. The Florida Department of Agriculture considers Dubia roaches a nuisance species, and they require a State-issued permit to import and keep them.
How long does it take for Dubia roaches to mate?
Mature adults often mate immediately upon introduction or shortly after when the environmental conditions are to their satisfaction.
Do Dubia roaches bite?
No. While they may scratch at skin they mistake for food when they’re hungry, we have never known them to attack people or animals.
Is there any way to make Dubia roaches grow faster?
Yes and no. Dubia roaches grow faster in favorable environmental conditions, like when it’s warm and humid, and increasing either will speed their growth to a point and within their natural limitations, of course.
Can Dubia roaches fly?
No. Adult males have wings (females don’t), and when temperatures are high they like to jump from high places and flutter to the ground. However, they are unable to fly.
Why are Dubia roaches so popular?
They are popular mainly because they are nutritious feeders for reptiles and other insectivores, they are easy to keep, and they are widely available. More information is available on this topic in our post about reasons to try Dubia roaches.
Can I feed Dubia roaches “cricket diet” or something similar?
It depends. Manufacturers typically design these products as gut loads. Gut loading enhances the diet of insectivores without regard for the insect. Therefore, gut loads may have a negative impact on Dubia roaches generally and Dubia roach breeding specifically, depending on what ingredients they contain.
What’s the best temperature to keep Dubia roaches at?
It depends what you intend to do with them. Dubia roaches grow and breed best between 85ºF and 95ºF. Dubia roach feeders can be kept at temperatures between 70ºF and 85ºF.
What colors do Dubia roaches come in?
As adults, their color varies greatly. Also known as the Orange Spotted Cockroach, Dubia roaches range from completely black to mostly orange with some black and tan spots, and almost any combination in-between. Nymphs, on the other hand, are always brown or tan.
Are Dubia roaches healthy for humans?
Hmm. Well…probably. People in some cultures eat insects, and Dubia roaches are high in protein and minerals. They’re healthy for reptiles and other animals that eat them, so it would seem to follow that they might also be healthy for humans. Something to think about (and not necessarily do).
Are Dubia roaches legal in Canada?
It’s unclear at this time. Canada requires an import permit for some cockroach species but not others. Dubia roaches are not currently among the cockroach species the Canadian government has evaluated for import (external link). They do allow some tropical roach species, so it seems likely that they would ultimately allow the importation of Dubia roaches.
How long does it take to start a Dubia roach colony?
It depends how many roaches you start with, how you keep them, what you feed them, and a variety of other factors. Generally, it can take anywhere from zero days to four months to establish a Dubia roach colony, depending where you start.
Can I keep all of my insect feeders together. For example, Dubia roaches and crickets?
Dubia roaches are mild-mannered and tend to keep to themselves. They will not attack other feeder insects, so as long as the other insects don’t attack them, the answer is yes.
Why are some Dubia roaches white or tan?
The outer skin of the Dubia roach is also known as the exoskeleton, which is a relatively hard and inflexible shell that provides structure to their bodies and protection from injury. The exoskeleton’s ability to expand is limited, so Dubia roaches must shed it and build a new one in order to grow. This process is called molting. It lasts an hour or two, and during this time, the newly-exposed skin that emerges as the old exoskeleton is discarded appears white or cream-colored. This fragile new skin hardens and darkens over the course of a few hours as it is exposed to oxygen and becomes the roach’s new exoskeleton.
Are Dubia roaches legal in Hawaii?
Hawaii is arguably the most restrictive State regarding live animal importation. They limit importation of most animals, including tropical ones, out of concern that non-native species may become established in the wild and harm the existing ecosystem. We do not ship Dubia roaches to Hawaii unless the customer has a state-issued permit.
How big do Dubia roaches get?
Dubia roaches can grow to about 1.5 inches under ideal conditions, measured after a meal. Because their abdomen elongates in the presence of food, a 1.5 inch roach may measure only one inch when allowed to go hungry for a number of days.
How long can Dubia roaches live without food?
Cockroaches are famous for their ability to survive famine. We have seen Dubia roaches alive after two months without food or water, such as when a package is returned to sender unclaimed. Of course, we suggest keeping your Dubia roaches healthy, which includes regular feeding.
Do Dubia roaches eat meat?
Yes. Dubia roaches are omnivorous, so they can and will eat meat. However, meat should be only a small part of a captive Dubia roach’s diet. They can live without it, and they live longer, reproduce more, and grow faster when fed a diet of mostly carbohydrates.
What are the highest and lowest temperatures Dubia roaches can survive?
This is a complicated question. Survive is different than thrive, and there is a temperature range and time-frame for both. In absolute terms, Dubia roaches die relatively fast around 120ºF and 32ºF. When it’s very cold, they become sluggish and they can stay in this state for a while. But they cannot survive freezing. Of course, none of these temperatures are anywhere near healthy for the roaches, which require a much tighter temperature range to grow, breed, and thrive.
Can Dubia roaches climb glass?
No, Dubia roaches cannot climb glass. Some roach species like hissing cockroaches can climb glass, but Dubia roaches cannot.
Are Dubia roaches dangerous?
Blaptica Dubia is not a pest roach species like German or American cockroaches. It is not invasive and is not a disease vector. Because B. Dubia is a tropical roach, it cannot reproduce in the wild in most of the United States. The two states with climates potentially favorable to Dubia roaches ban their importation. In most of the US, Dubia roaches that escape captivity die from exposure to inhospitable environmental conditions or lack of food.
