Dubia Roaches vs Common Feeder Insects

December 01, 2020

Feeder Insect Nutrition Chart

One of the complications that goes along with keeping most reptiles and amphibians is the need to keep other creatures alive as well, namely their food. Reptile and amphibian keepers want feeders that are nutritious, easy to keep and not disruptive to the household. We at DubiaRoaches.com feel that Dubia Roaches are the best choice to meet all of those needs. Let's take a look at the advantages of Dubia Roaches compared to other popular reptile and amphibian prey:

Dubia Roaches vs Crickets: While both of these bugs are lively and active, provoking a strong feeder response, crickets can be a little too active, easily getting loose in the home and chirping endlessly under the refrigerator. Dubia Roaches, which don't climb or jump, aren't likely to escape their cage and infest your home. In addition, they don't make noise! Dubia Roaches are odor free, even if they die, unlike crickets, whose decomposing bodies are quite stinky. Please see our nutrition article for more information about how Dubia Roaches compare to crickets.

Dubia Roaches vs Superworms: Some reptile keepers use super worms as a staple food, due to their relatively long period in the larval stage, meatiness and greater activity level that provokes a strong feeding response. Dubia Roaches are longer lived than super worms, more mobile and don't burrow into loose substrate. In addition, if a Dubia Roach gets loose in the home, it will most likely die, instead of returning to haunt you in the form of an inch-long black bug. Superworms are similar in nutritional content to Mealworms (see above) but have even more fat.

Dubia Roaches vs Mealworms: Dubia Roaches are more active than Mealworms and more likely to be noticed by your pet. Unlike mealworms, Dubia Roaches don't burrow into a loose substrate and become inaccessible to the hunting reptile or amphibian. Mealworms have somewhat less protein than Dubia Roaches, quite a bit less calcium and nearly twice as much fat. While mealworms can only be eaten during one phase of their life cycle, Dubia Roaches are an attractive food for their entire lives, from nymphs to adults.

Dubia Roaches vs Silkworms: Silkworms and hornworms are quite a treat for most reptiles and amphibians. They are much lower in fat than Dubia Roaches but also lower in calcium, and contain half as much protein. They are, also, delicate, expensive and can be difficult to care for. Dubia Roaches are cheaper, hardier and easy to feed and house.

Dubia Roaches vs Hornworms: Hornworms are enjoyed by many reptiles and amphibians. Their large size range makes them attractive to reptiles of many sizes. Their nutritional makeup is similar to that of silkworms --very low in fat, lower than Dubia Roaches in protein-- but they are higher in calcium than silkworms. They are expensive per unit and consequently are not practical as a staple food. Dubia Roaches are cheaper, hardier and easy to feed and house.

Dubia Roaches vs Fruit Flies: Fruit flies are similar in fat and protein levels to Dubia Roaches. They are higher in calcium relative to other feeders (though not Dubia Roaches) but since they're also higher in phosphorus, their calcium to phosphorus ratio is about the same as other feeders besides Dubia Roaches. Beware, though: even the "flightless" fruit flies seem to manage to escape their enclosures and get into the household. They are also very tiny and only suitable for the smallest reptiles and amphibians. Dubia Roaches are much easier to contain. The smallest Dubia Roach nymphs are a good substitute for the larger species of fruit flies in terms of size and ease of consumption.

Reptiles and amphibians do well with a variety of prey to provide the best nutrition and varied hunting experience.  All the feeders described above have their place in the reptile diet.  However, we at DubiaRoaches.com feel that Dubia Roaches are the best staple food for all your reptiles and amphibians of any size.
