My rat colony has got these little red bugs/worms so tried using Nix but didn't work, However, all i did was spray the sides of the tub and in the shavings...gave it a week, still got bugs..So i googled what else i could try.

I was going to use Hartz flea and tick kitten spray on the Adult rats, and give it a week. If bugs are gone change shavings....

When (babies born a week from now) would it be safe to use the young pups to feed. Or could mom still rub poison on the young in a weeks time.

How long should I wait to start using young as feeders again?
