How do I clean my Blaptica dubia roaches?

Blaptica dubia roach cultures may need to be cleaned every 6-8 months. At Josh’s Frogs, we recommend seeding the substrate of Blaptica dubia roach cultures with springtails, a small soil isopod that breaks down organics. This significantly reduces the chance that mold will grow in the Blaptica dubia roach culture, which can kill Blaptica dubia roaches. Most of the substrate should be changed in Blaptica dubia roach cultures every 6-8 months; when doing so, make sure to add some frass (roach waste) back into the cleaned culture. Frass in an important dietary component in Blaptica dubia roach nymphs, and is needed for a healthy culture. Fortunately, Blaptica dubia roach frass does not smell.
