This has been going on for a while.
Little black ants are loving our house. They have been in the main living/kitchen for a while. Now they have even reached the second floor and settled in the main bathroom.
The usual fly spray of course works, but it's only treating the symptoms. I can't get them to learn to stop using that route (ie. to stop getting into the house). The spray stinks too. So I don't really want to have to keep using the spray.
Is there a smarter way??
Oh, both attacked areas are probably nice and warm for them, being sort of on the sunny side - if that matters ...
