Keep ladybugs out of the home by caulking all indoor and outdoor cracks and seals around doors and windows. Fix broken window, attic and vent screens. Close any holes to the attic. Check seals around siding and weatherstripping.

Remove dead and living ladybugs in the home by vacuuming the ladybugs and discarding them outside. Sweeping can also remove ladybugs, but they may secrete yellow blood. Wash any yellow blood stains off the home or walls, as the blood attracts more ladybugs.

Ladybugs prefer lightly colored homes and the warmth provided by afternoon sun. A light-colored ladybug house, placed outside your home, might deter ladybugs from entering your house. Place the ladybug home facing the southwest afternoon sun.

Ladybugs are difficult to get rid of once they have infested a home. Due to the ladybugs' scent remaining within and on walls for years, ladybugs often return. Apply insecticide outside the home in the fall, as sealing all cracks and holes might be impossible. Per the University of Kentucky, you should avoid using insecticide inside the home, as it has proven ineffective toward ladybugs. Contact a pest control company for additional assistance deterring ladybugs from returning.
