I don't think he will eat poison directly! Better you keep it or mix it with the peanut butters! I think he is coming from your ceiling! A small hole can be enough to let him enter to your house!
Anyway I had few battles against them before and almost won all battles :D But after all I feel shame and I feel guilty! I had to kill them, I had to poison them :/ It's a very guilty feeling for me :/@exyle,
Cheers~
