I need a home made ant killer. My patio is overrun with big black ants

Apply corn meal

Boil water and pour the hot water on the ant hill

the best thing I've found is lots of peppermint oil and Bounce original scent dryer sheets. I saturate peppermint tea bags with the oil and put them in out of site places all around our home> Then I put the dryer sheets in chairs, under tables, and any where else that the ants gather. It works inside and on the deck. I haven't tried it in the grass yet.

Boric Acid, water and sugar. This recipe is from Food.com but don't eat it and it is suppose to work wonders on ants! Good luck! http://www.food.com/recipe/get-rid-of-ants-ants-ants-203233

Their carpenter ants, and they love wood like termites do. I'll get back to you, once I find my page with homemade ant killer. I would still call an exterminator, if their that bad. Good Luck!

You have carpenter ants, and they like wood, like termites. Call an exterminator if it's that bad. I have a receipe for killing ants, but I don't have it now. Will look for it in a few minutes. GL!

They love sugar, I have mixed sugar and Sevin dust but using a bait as Terro is inexpensive and effective

I agree, cornmeal, they can't digest it, and die

packaged cornbread mix that says it is sweetened and put it where they are coming in if you can find it, or even on your counter in a small lid. They will take it to the mound, everyone will eat it and die, they can't digest the cornmeal, but will take it because it is sweetened. Little goes a long way.
