Ants have taken over our paver patio and there are ant hills all over. We put it in 3 years ago and haven't had problems until now. Any ideas for how to get rid of them? I'd really prefer something that isn't toxic to pets but I'll use chemicals if I have to.
I've tried Epsom salts around the mounds which sort of worked. There aren't as many ants but they're still there. I've also tried soaking the patio with water and that didn't work either.
