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.
