They are doing a great job with our ant problem, we haven’t seen many since they have been coming, which is fantastic! The only issue is that we have a dog, last time they came no one was home and they sprinkled something in our backyard near the deck. When I actually looked up what it was, it said it wasn’t bad for dogs as long as you wet it and allowed to dry after it was applied. I took notice The white sprinkles of our deck two days after they were there. It would’ve been nice to know that I should’ve let them in soon as I came home, to protect my dog .
