Blaberus discoidalis Care


This page is for the one of the larger cockroach feeders, Blaberus discoidalis, the Discoid Cockroach. Discoids are a medium-large sized (2"-2.75") species of common feeder cockroach. This species makes a fantastic feeder and is a moderately fast breeding (Live Bearing) cockroach with a fast growth rate for its size. This species is not sexually dimorphic, males and females look the same but females are generally heavier. When feeding off adults of this species you should first choose the adult males. It's best to keep a 3:1 female/male ratio or less because males are prone to fighting which can disturb the colony.


Species Specific Care: B. discoidalis
Blaberus discoidalis is a very easy cockroach to care for and is rather forgiving with husbandry mistakes. These cockroaches can neither climb nor fly and do not require a barrier. They cannot infest your home unless you live in the lower tropical reaches of the US (IE Southern Florida) as these are from tropical Central and South America and rarely breed below 68ºF. 

Checklist of items to have ready before your cockroaches arrive: Discoid Roaches
1.) Plastic Rubbermaid style bin with a window cut out (glue in window screen).  If you want to show these wonderful animals off, a glass tank 10-20 gallons in size that has a built-in screen lid. I personally use sterlite bins because they are easily stored and maintained but I have used a glass tank for 3 years prior with great success. This includes no substrate with eggflats, and substrate with cork bark. Both work well but the eggflat allows for more hides and better breeding. 
2.) Eggflats are ideal for productivity with this species as the enclosure is not very humid and do not mold quickly. I recommend the use of corkbark regardless because it doesn't get soggy or mold and makes for great decoration. These animals prefer it hot and lightly humid, 75ºF-90ºF and 65%+ humidity. Regardless they still do well at room level humidity with moderate weekly mistings.
3.) Substrate is not needed with this species if enough hides are provided. But, I always recommend substrate for moisture control and odor reduction. In a show tank a substrate is a must. What natural setting doesn't have dirt or leaves? You can include fake plants as well but be aware that roaches will eat live plants and they could be toxic to them. 
4.) A food dish. Keeping food in a dish helps to reduce mold and you can avoid misting the food by simply pulling out the bowl when you do so. 
5.) A water dish, remember roaches need moisture in either their diet or as a straight water source. You can use water gel or a shallow bowl filled with water and pebbles to keep the roaches from drowning.

Nutrition: 
B. discoidalis will eat an average amount compared to other similarly sized cockroaches. You should always keep a protein supply (dog food works well) and a moisture supply (oranges, water gel, water) at hand in their enclosures. Remove food immediately once it starts to mold or rot.
