    "Works great for June bugs in east TX!"

    We have used these beneficial nematodes to get rid of June bugs in east TX for years. Also helps with fire ants too!

    "It works!!!"

    Some people don't believe that microscopic worms control fleas in our heavily wooded yard, but ANTidote sure works. Our two dogs have had two relatively flea-free years since we first applied ANTidote (once each spring). It's a great value, and it's good to know we're not poisoning our yard or area waterways with chemicals.

    "No poison needed"

    I'm in the deep south. I first used this almost ten years ago. To this day when ants move into the yard all I have to do is make sure the ground isn't terribly dry and be patient. The nematodes multiply, the ants move two or three times trying to escape and then they are gone. Takes time but works. Don't have fleas in the yard either in spite of squirrels etc... Now giving as a gift.
