Dog safe ant removal products / methods for outdoor use?
DH and I are re-arranging patio stones in the backyard to make a platform for the dog's kiddie pool - ONE of the patio stones we are moving has a small ant colony underneath it. We had no idea they were there... no other signs of them anywhere in the yard or around/in the house.
Since the dogs are exposed to the area, I am wondering if anyone knows any dog safe methods of killing the ants? I've heard of using borax to kill, and peppermint oil as a deterrent? Borax is obviously not good for dogs...
Any suggestions greatly appreciated!
