Carpenter ants are sizable black or dark as well as brown ants. They are actually most active during the course of the evening hours, especially in the course of the warm summer season. They are named carpenter ants as a result of their routine of hollowing out hardwood to produce a nesting site.Our team don't experience woodworker ants everything commonly in the Fresno city location. They are certainly not a significant pest trouble on the San Joaquin Lowland floor.
