½-inch Dubia roaches are only a month to six weeks old, but in this time they’ve increased their weight tenfold. While impressive, they’re still a long way from maturity. At a half-inch, they’re only a quarter to a third of the way to their final adult size. This fact has important implications for their role as feeders.
First, they’re soft-bodied. This means they are easier to digest than larger roaches and many other feeder insects. Better digestibility means more nutrition per ounce, and we’ve seen anecdotal evidence that this has actual benefits in the real world. It’s common to hear reports that animals eat fewer Dubia roaches than other feeders. It certainly follows that better digestibility leading to more nutrition per ounce leads to getting full faster, and ultimately eating less.
As you can imagine, better nutrient availability has major benefits for insectivorous animals. But this is especially true for the young and old animals, or those experiencing stress – whether from an illness or captivity in general.
Second, because they’re fast-growing and self-select certain nutrients, ½-inch Dubia roaches are great for gut loading. You can offer them healthy whole foods, and that nutrition can then be passed on to the animal that preys on them.
These things make ½-inch Dubia roach nymphs particularly healthy for fast-growing insectivores. It also makes the job of gut loading easier, more reliable, and more beneficial. What better scenario for gut loading than a nutritious primary feeder with a big appetite for the nutrients your animals need to grow healthy and strong? Half inch Dubia roaches have this, and more. They’re a win-win for your animals!
Having said all this, we understand if none of this makes sense and you just want the best feeders for your animals. We worry about these things so you don’t have to! Just select the right size Dubia for your animals and you’re good to go!
½-inches is one of the most popular Dubia sizes. They tend to work for small bearded dragons, small to medium chameleons, small tarantulas and pixie frogs, and other similarly-sized animals.
½-inch Dubia Roach Sizing Notes
½-inch Dubia roaches range from ½ inch to ¾ inch. Some size fluctuation is normal. Their size may vary by hydration and feeding status. You can increase or decrease their size by adjusting their food and water intake.
Store your Dubia feeders at room temperature (or slightly lower) to maintain their size. Store them at 80°F or higher and provide unlimited food to increase their size.
