I've read several posts about it on here. I notice today that
www.chasingame.com did a test with
ortho home defense insecticide and found that it does work and doesn't spook deer. If you want to read it, go to hints and tips on there site and scroll down to the middle of the page. They have it written out well , along with test photos. Good luck to you guys with ants, Hoped I helped someone.
