I hated to use the nasty chemicals too. But I ended up using them in the end. Good luck.Ugh...after 2 and a half hours, the deed is done. If it aint dead yet, it will be soon! Managed to hit the big coop as well with the spray and dust. I definately dont like using the chemicals but hopefully it works. Going back out to burn. Its cold out so hopefully the fire will keep me warm!
