How to kill ants?

Sugar and borax mixed in equal parts. Leave out where ants will eat and take back to nest. Sugar attracts, borax kills.

Here's a vinegar based recipe

We have had good results with Jiffy cornmeal mix right out of the package, sprinkle it ouside the room where you see ants-usually this is the kitchen or bathroom. They take this back to the colony and it kills the workers. it will not kill the queen(s) who are there to reproduce. The queen would need poison.

Ants also leave a trail of pheromones so other ants can follow them, you will need to clean this up, use which ever counter cleaner is recommended for your counters.

A product called Terro is very effective, it is in liquid form & you can find it at Walmarts and diy stores, we put down on the provided cardboard and they love it, take it back to their colonies.

Another Hometalker used medicated powder from Dollar Tree around the foundation of the home and the ants were gone in 1 day. Although I have not tried this it sounds like it might have some merit.

Hi Rhetta - Those little buggers are relentless, aren't they?!? This is the most effective method and all-natural spray DIY that we use with ants. It's best indoors, but will also work outside with more frequent applications. Hope this helps! Hugs, Holly

I use packaged cornbread mix that says it is sweetened and put it where they are. 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.

I read this from : Itsmemic

Medicated powder from the Dollar Tree. It has eucalyptus in it...menthol...I puff it around my homes foundation..and inside under my birdcages in the cracks under moldings. Work immediately and they never come back. I do this at the first sign of ants..in one day..GONE. The powder is in a very large container and lasts quite awhile too !! And smells great !

Not toxic to my birds OR dog

What if you make a barrier around the house.

I did some research, since we know what works for one person doesn't always work for another. I found this site and it's pretty informative. I know some tips you may not be able to use but there are some good ones also that will hopefully help.

Ants are so weird. One time I found them inside the freezer in the garage!! What would possess them to go inside a freezer only to die? They must have sent signals back or something ~ there were no ant trails only a freezer full of dead ants. Hasn't happened since.
