My chickens won't eat them either. Lol. No, we haven't tried soapy water. Never heard of that one! But I'd try about anything at this point. It really didn't. Just dumped them all into a coffee can, dumped in some gas, & lit em up. Lol What is BT?? We have 140 hills of potatoes, hand picking is HORRID! Sevin hasn't worked at all for us. We've always used that, but this year its just not doing anything.
