Nests near homes, however, may prove a source of irritation. If the nests are large or difficult to approach, for example within the walls of a house, the safest procedure would be to hire a pest control operator to eliminate the colony. Any attempt to remove or destroy nests by the layman should be done at night when nest activity is at a minimum. It is important to note that even though nests are relatively inactive at night, any disturbance will result in instant activity by the colony. It is necessary to work cautiously but quickly.
Protective clothing is advisable.
