Did you read the label on the poison container? I use sevin dust. I stir up the mounds real good, then heavily sprinkle sevin dust on them heheheh. BTW: Chickens wont mess with sevin dust. I've used it to dust chickens for lice, once they're released the chickens shake themselves off and go on about their business.I have several fire ant hills I would like to poison. My birds are pastured. Is it safe to put out poison with them running loose? Or how long do I wait to let them out after putting it out?
