Hi
I once again have a large infestation of small insects in my ball's tank. They look like flies about the size of a pin head. About a month ago i noticed them at first and i completely cleaned out the tank, replaced the substrate, used a bleach and water mix to clean everything, and let it dry. Now i noticed them starting again, there are hundreds of them!! they are all gathering around the water dish, i have cleaned it out 2-3 times a day killing many of them, but they keep comming back. Does anyone know any tricks to kill these pesty things? I know they arn't feeding on any fecies from my snake, she hasn't eaten in 6 weeks and the last time she "went" was before i cleaned the tank. I don't know what they are feeding on... I am wondering if they are comming in the substrate. Its winter right now and the warmest day we have had in a long while has been -5 'C, and there are no insects like this flying around the place, they are convined to the tank. please any insite would help.
