  • Scientific Name: Blaberus Discoidalis
  • Lifespan: Approximately 1 year.
  • Handling: You may handle discoid roaches whenever you’d like. However, if the discoid roach you are handling feels threatened, it may let off a bad scent (smells a little sour). However, they rarely let off this scent, with most people reporting that they have never even smelled it.
  • Size: Approximately 2-3 inches, females being larger than the males.
  • Care: Easy
  • Community: Yes, as long as you have lots of room for them to move around.
  • Lifestyle: Nocturnal, active at night.


A Rubbermaid container does best in housing multiple discoid roaches. The size depends on how many discoid roaches you will be housing in a single enclosure. The reason why most people choose Rubbermaid containers is because of the slick sides that it has, not allowing the discoid roaches to climb them.  No ventilation is needed in these enclosures, as they like their environment humid.


1) Egg crates, paper towel rolls, toilet paper rolls, and etc are great things to include in the enclosure. During the day, most of the discoid roaches will spend their time in these to sleep, hide, or relax in. If enough is not available, they will try to climb on one another and overcrowd one specific area of the enclosure. This is why, you must put enough supplies  for all the roaches to live comfortably.


2) Two bowls

  • One bowl to hold your food source which may contain your homemade roach diet or commercial roach food diet.
  • One bowl to hold your water source which may include fresh vegetables, water gels,wet paper towel, and any other source of hydration.

Lighting and Heating

Discoid Roaches do not need any special lighting whatsoever. The only thing they need is a source of heat through a normal house bulb or heat lamp.

Temperatures should be…

Day Time

80-90 °F is recommended. 95-105 °F is recommended for best reproduction results.

Night Time

No lights are necessary. 70-75 °F is recommended. If it is too cold to achieve this temperature without lights, I recommend using a heat emitter or a reptile infrared heat light. Make sure to check temps at night, to reassure the temps are good to avoid stress.


Discoid Roaches will eat just about anything. A high protein diet is recommended. You may make your own using a recipe provided by one of our members on here or you may go buy a commercial roach food diet sold in pet stores.

Humidity and Hydration

Humidity is something they need to live a good life. The humidity levels should be mid way at about 50%. To reach these levels, it is recommended to spray down the enclosure once or twice daily, depending on where you live. Some places are so humid that spraying isn’t even needed.


Hydration is something very important for discoid roaches. With such high temperatures, hydration is needed every day for the discoid roaches. You may hydrate your discoid roaches with water gels, carrots, slices of potatoes, and etc. If you choose to use fresh vegetables, make sure to replace them every other day to avoid bacteria and mold build up.



The best substrate for discoid roaches, is no substrate. This will make cleaning the container a lot more easier.
