I have several colonies of springtails and pillbugs/sowbugs, and one big colony with Dubias for breeding, tenebrio obscurus, lesser mealworms, demestid beetles, pillbugs, sowbugs, and springtails in it. Suddenly I've noticed that all of the colonies are infested with tiny red bugs that seem to be mites. They likely got into the house in the first place by hitchhiking with one of the freshly caught batches of pillbugs (I have about a thousand I gathered from my yard). Are these things dangerous to me or my insects? What should I do about them? Any advice would be much appreciated!
