A few weeks ago I noticed some mites ( possibly Acarus sp ) in my ants foraging area and small number in the nests. I believe they came from the meal worms and or super worms I been breeding. The colonies with some mites don't seem to be having problems. I'm wondering if they could harm the ants or brood in any way? If so I can't seem to totally wipe them out, would keeping their population down make it safer?
