I bought 20 weened rats from a pet store that was going out of business. I put them in one of my grow out tanks and after I finished feeding last night I was cleaning all the water bowls and I thought my snakes had gotten mites.So this morning when I went to clean the rats the shavings in that tank was covered in mites and so was the rats. I sprayed them all with flea and tick spray and the washed them off and bleached the tank.I checked all the other rats and mice and they all the rest were good. I guess they could'nt get out of the glass tank to get to the other tanks or into the breeding rack. what else can I do?
