Breeding Dubia Roaches

IMPORTANT: Please be aware that we DO NOT recommend starting your own colony unless you are absolutely set on doing so. Not only is it common for people to develop an allergy to dubia roaches or their frass (droppings) with too much handling and constant exposure, but the amount of time involved in sorting out and maintaining a colony is more than you might expect. You might save money long term, but it may not be worth the risk. Handling your dubia roaches in a well ventilated room, and wearing gloves or even a mask if possible can help reduce the chances of an allergic reaction. Our facility has been specially equipped with high quality ventilation to manage this problem. Let us provide your dubia roaches as you need them with minimal exposure and risk of developing allergies.

If you would still like to start your own colony, you can learn more below:

Breeding Dubia roaches is very easy and is almost a by-product of proper care: if your roaches are housed, heated and fed correctly, they will breed on their own. Temperatures of at least 85F are required to breed Dubia roaches successfully. Although they appear to be live-bearers, their birthing method is actually an intermediate stage between egg-laying (oviparity) and true live-bearing (viviparity). Dubia roaches are “ovo-viviparous”, meaning that the egg sac (called an “ootheca”) is stored in the female's body. When the eggs hatch, they exit the female's body as small, 1/8” nymphs. In order to ensure breeding, a Dubia roach colony must consist of both adult males and females. Dubia roaches are sexually "dimorphic", meaning that the males and females are easy to tell apart. The males have complete wings (which do not allow them to fly) while the females have wing stubs only.

The difference between the male and female can be seen here: Since a single male can fertilize multiple females, it's best for the breeding Dubia roach colony to have more females than males. This can be easily accomplished by feeding the adult males first to your pets. Females are mature and ready to breed by 3-4 months of age. They will produce approximately 30 nymphs every two months or so during their active breeding life. Nymphs have soft bodies and shed fairly often as they grow to adult size and develop the hard, or chitinous shells of adulthood. For best management of your breeding roach colony, maintain a ratio of approximately 1 male to every 5 females, keep temperatures at 90-95F, and keep track of the rate of hatching. If the rate decreases significantly and husbandry remains correct, most of the females may be older and producing fewer young. In this case, be sure to allow more females to mature and reproduce.
