What I have had success with is jiffy cornmeal mix right out of the package, no baking.
The worker ants take it back to the colony and it feeds and kills them. And for the queen, we use a product called Terro, available at DIY stores in the pest control section.
Just follow package directions.
Luz, corn meal is indeed the answer: https://www.hometalk.com/36651130/ants-safe-and-effective-cure
I didn't have any cornmeal on hand, so I mixed powdered sugar with baking soda and it worked, too. Perfectly...they're gone.
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.
