Since this is a day-active ant, they tend to be observed more than other carpenter ants that tend to be nocturnal. Compact carpenter ants are rarely observed inside structures but have been seen entering under doors, cracks around windows and structural cracks and crevices. Both the flight season as well as flight behavior have not been documented in C. planatus . Foraging and Feeding Workers are seen foraging in very dispersed trails or singly. Foragers have been observed on trees, bushes, along sidewalks, through lawns and exteriors of structures.
Nests are usually difficult to find.
Management Residual surface sprays will control the common complaints of compact carpenter ants as nuisance pests on building exteriors. If they can be found, direct sprays to nesting sites are recommended. Baits placed along trails will help in reducing colony populations. Caulking exterior openings and weather striping may also aid in control. Read and follow label instructions and precautions before using any insecticide.
