Distribution: India

Description: The Question Mark Roach (Therea olegrandjeani) are a small beautiful pet roach. They make an excellent pet and are a great conversation piece. They adults can climb glass or plastic. These roaches take two years to reach the adult stage from the time they are born.

Nick Names: Question Mark Roach

Size: 1/8th inch when hatched to 1 inch as adults

Sexing: Adult Therea olegrandjeani are sexually dimorphic, males have wings and females do not.

Lifespan: 2-3 years

Difficulty Level: Easy

Caging: Therea olegrandjeani adults can climb glass or plastic. The nyphs do not climb as they try to bury in the substrate. We keep ours in Kritter Keepers so that we can watch them but any sterilite container with a vented lid would work just as well.

Substrate: I use egg crates positioned vertically for additional floor/living space in the sterlite tubs. A deep dry substrate of peat moss and hardwood leaves such as oak iis needed to keep the nymphs happy. If you use any kind of substrate from a hardware store or garden center, MAKE SURE IT IS FERTILIZER AND PESTICIDE FREE!

Required Temperatures: 78 - 95 degrees F

Humidity: 40%-50% You can keep a spray bottle handy to help keep humidity up in dry areas. If you use a substrate wetting it down periodically can help maintain proper humidity as well.

Food Requirements: They will eat almost anything. I keep my home made dry roach food available to them at all times. When feeding any fresh fruits or vegetables, do not put in more then they can eat in 24-36 hour period to avoid problems caused by rotten/moldy food.

Maintenance: Keep food and water available at all times. Clean out the waste as needed. I do not allow the waste to get any deeper then 1/2 of an inch. I also leave some in as the babys seem to do better when they can feed on their parents waste. Since this species lays eggs it is important to remove the ootheca from the waste before disposing of it.

Breeding Notes: Females can lay copious amounts of egg cases, each containing 20-30 roaches. The ootheca are susceptible to drying out so make sure the humidity stays up. The ootheca will hatch in 3 months depending on temperature and humidity.

This roach can not be mailed to Tennessee or Florida!
