Carpenter worker ants are 1/8" - 1/2" long and Queens are 1/2" - 5/8" long, black in color.
Carpenter ants occur in large colonies with several queens. Colony nests can be found in wall voids, insulation, rotting fence posts, decaying trees and can be very destructive to timbers, they will forage up to 300 feet from the nest. Carpenter ants are attracted to honey dew, fruit and plant juices, sweets, eggs, meat and insects.
Most infestations of Carpenter ants can be controlled with Clark's Year Round Pest Control. However, in cases of heavy, difficult infestations a combination of residual barriers and baits may be used.
