Carpenter Ants are black. They are large. 1/4 to almost 1 inch.
Carpenter ants are nocturnal and will exit their nest galleries 15 minutes after sunset in large numbers. Frequently form satellite colonies within structures near moisture or heat sources.
Carpenter ants invade kitchens during the summer months in search of food and water. Can invade the structure if moisture damage is present.
Granular baits applied around the perimeter of the structure and within the landscape work well to eliminate carpenter ants. Gel baits applied along known trail locations. Perimeter treatments with non-repellent products.
