I know I read on another forum that ants don't like mint. Perhaps that would work on your little critters, too.
Make a really strong mint tea and spray it in the areas that you have problems. No harm to the furkids and it smells good, too! Couldn't hurt to try it.
PS I also have a contractor (Western) come out and spray because our lot is wooded and we get spiders!
The products that they use are safe for pets, too.
