I just have to say getting some high quality clove oil was a godsend. I really doubted it. They obviously cannot stand that stuff. Be liberal with it. Put it all around where they come in, run it along sides and corners. Make sure they've got to go through it to get anywhere. I just used the dropper for it. And I still have plenty to keep up. But it really smells like cloves for a while. We've tried so many things. Could not believe how quickly and easily and well that worked! I was vacuuming up their poops every single day. Knew where all their favorite spots were because of it. Within 2 days nothing. Nothing to vacuum. No holes chewed in the bottom of feed bags. Just nothing.
