Yes! Before ant season, (I have a house in GA) I would put granules from Home depot around the perimeter of my house. Two weeks after that I would spread it throughout the sides of my house a little further out. I also put uncooked grits around the outside becasue they would eat the grits and it would expand and kill them. After all that I did not have a problem with them, spiders or scorpions. You have to start early enough in the season and treatment is continuous.
