I looked at my blatta lateralis colony today and then I noticed the poop was moving. At closerninspection, there was a white less than 1 cm long but its thickness is no thicker than a penny crawling thing. It crawled like a caterpillar. Then at the corner of the colony, there was a number of them crawling. Idk but I think kts fly larvae. Should I remove these? Will the presencd of these weird crawlies benefit my roach colony and if so, how? Or will these damage the colony?
