Maintaining roach tubs to feed your reptiles can be a messy, arduous process. This ABDragons Black Cleaner Beetles Small Pet & Reptile Food can help. The Alphitobius diaperinus—or the black cleaner beetle—eats dead roaches and helps with mold, fungi, mites and flies. This natural process helps prolong the time between cleaning roach tubs. Bonus?
