Ladybugs are beneficial insects that eat harmful aphids and scale insects. In the fall months from September to October, ladybugs may invade homes to overwinter. To prevent ladybugs from entering the home, homeowners should seal cracks around windows, doors, siding and other areas, and repair or replace damaged screens. If ladybugs have already entered the home, they can be gently vacuumed or swept up and released outside.
