RIA Extermination inspects areas where ants have been observed to confirm their activity. For professional ant control for your home or business, contact us today! Pavement ants love to build nests under slabs, so we focus inspections on slabs and masonry areas, both interior and exterior. We look for small piles of dirt, as sidewalk ants often kick up dirt from the ground below. Ants may invade to find food or water, so we inspect kitchens, baths, and other similar areas to locate activity. Note that sidewalk ants often feed hundreds of feet away, so we also follow their tracks to try to determine where they came from.
