I use the gallon sized concentrate of the Gordon's Permethrin 10 and follow the instruction's on how much water to add. I have been using it to attack the ant's around here. 2 year's ago some of the ant's ate a batch of my chick's up out there in the grow out pen. But, this stuff will take care of a lot of different type's of insect's. It's for use on livestock, and that include's poultry. This gallon size will last you awhile, as it is a concentrate.
I'll pick some up when I go to town to pick up other things
