If i buy some domesticated rats. Will they eat the bed bugs. I have had rats previously and i would let them run free and when i let them out to do that theh would walk up to u and around h just like a cat woukd theg would come up out of no wherr and just sit next to you our on you while its on your couch. So would it be possible that if i let them free and train them the same wag would they eat the bed bugs if theh come across them
