Ladybugs are important beneficial insects to have around as they prey on aphids and other insects that can destroy gardens and crops. However, in some areas, these beneficial beetles can become a nuisance when they enter homes. Ladybugs are overwintering insects and when one ladybug finds a suitable spot to hibernate, it produces a pheromone that attracts other ladybugs to the site. It is not uncommon to find dozens, if not hundreds of ladybugs congregating together in clumps. Quite often, a few misguided beetles get confused and enter homes through electrical outlets and other openings in walls. If you suspect a ladybug infestation, contact your local pest control company.
