Ortho Orthene Fire Ant Killer1, Kills Queen, Destroys up to 162 Mounds, 12 oz.

This stuff smells absolutely horrific, but it is by far the easiest and most effective product ive tried to combat the fire ant hills that would otherwise take over my front and back yard. I strongly recommend wearing rubber/plastic gloves when handling this stuff as it has a noxiously pungent sulfur smell that will stick to your skin and clothes so takebit from me, get some gloves and handle with care or youll end up smelling rotten eggs every time your hands are near your face for 2 or 3 days. but, that being said, if you have an issue with fire ants that seem to think your yard is prime real-estate, just a small sprinkle of this stuff is all it takes to erradicate even very large colonies practically overnight.

This is all you need for ants. It doesn't take alot either. As I got near the bottom of the jug I only sprinkled a teaspoon on a big mound. It killed them all. I keep it up high in the utility cabinet inside to keep the ingredients active and it has lasted years!! Be sure you keep all insect killers inside if you live in a hot climate. Heat of 80 degrees or higher starts inactivating the ingredients.
