Pavement ants are no picnic! While they are an occasional nuisance, in large numbers they can be a terrible problem. You can see all their little anthills pop up in the hot summer months when lawns may dry up and provide more nesting opportunities in patches of parched earth. Although pavement ants don't as a rule nest inside, they will invade structures in search of food and are a particular problem in areas where slab-on-grade construction is prevalent. Using baits and non-repellent liquid sprays Guardian Pest Control can quickly eliminate this little pest from your home.
