I did a walk in at the vet in Hilo about 2 months ago and have been using it ever since. I live on the island of Hawaii and originally wanted to know how to keep these crazy ants away from my birds. The vet told me that it would help with ants, parasites, and mites. Apparently mutes are all over the island and because of humidity would likely have a problem before I knew it. I'm curious to know how it will harm my chickens cause it keeps the little fire ants at bay and my chickens seem pretty happy. You guys are worrying me
