I keep my crickets in 10 gal. tanks, I clean the tanks every other day, as well as change the water and food. They are in a stable dry warm room 78-82 degrees. Lately, they've been dying off like crazy! The only thing I've done differently in the last 6 months, is change egg carton types (once a week I exchange the old and give them new cartons) to recycled paper. I've also started to use Virosan (Nolvasan) disinfectant solution. I use it to clean all my feeder tanks from super worms to roaches. Whan I clean, the frreders are in a seperate, clean tank. All my other feeders are healthy. I'm losing several hundred crickets a day. Some of the crickets are turning red (If you want to see a picture, just ask). Most just look black when they die. When we've recieved the crickets the last few times, there have been a lot of gnats in with the crickets, as well as a few spiders. Not sure if they have anything to do with it. I called to place where I get my crickets, and they said it was the solution, and that the solution will kill chickens to. Has anyone herd of that before? We would love some opinions on what you think. Can gnats infest crickets? Could the Nolvasan solution be causing the deaths?
