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.

thanks for the info! here in the south, the ants are horrible

I had already read that at Chasingame. Pretty cool test.

I had ants in my Cudde this summer. I blew them out with compressed air and threw it in the freezer for a couple days.

Took it out of the freezer and blew out more dead ants and it still works great.

It seems those little buggers love to nest in them !! Thanks for the tip !
