I wish I knew the answer too...
In the house or the yard and gardens? In the yard, see if you can find the mound, sprinkle the mound heavily with sweetened cornbread and muffin mix. They go for the sweet and they can't digest the cornmeal and die. It may take more than one application depending on the size of the mound and the size of the ants, but it does work. I have put it on the trails they use, but it hasn't been as effective and a lot slower. I have a large shaker bottle that I saved from my cayenne pepper powder that I use for rabbits, squirrels and chipmunks and it holds a couple of the cheap envelopes of the mix in my gardening bucket (I get my containers of cayenne at Sam's Club).
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.
