Ladybug infestations often involve a ladybug-lookalike: the Asian Beetle. Asian Beetles often infest homes, and because the two bugs look so similar, people often wonder how to get rid of their "ladybug" problem. Although both bugs provide beneficial services by eating aphids that can harm plants, few people want them in their homes. Fortunately for homeowners, what gets rid of the one gets rid of the other, so the question of whether you have a ladybug or an Asian Beetle becomes somewhat academic.
Poke all but two inches of a nylon stocking into your vacuum cleaner's attachment hose.
Fold the remaining two inches of nylon stocking over the edge of the vacuum's attachment hose.
Secure the vacuum wand attachment to the hose.
Vacuum all visible ladybugs.
Remove the nylon hose from your vacuum cleaner.
Empty the hose in the trash or in the woods far from your house.
Prevent the infestation by repairing holes in screens. The screen patch consists of a metal mesh with adhesive that can securely fix holes in screen doors ladybugs can use to gain access to your home.
Seal your screen door where it fits in the frame by replacing the screen door flange or ensuring it has no permanent folds.
Seal your window screens using a screen patch.
Spread a 6-inch perimeter of diatomaceous earth around your home or around walls with windows. Diatomaceous earth consists of a pumice-type soil with anecdotal evidence as an insecticide.
Spray a mist of pyrethrin around exterior walls containing doors or windows using the gallon bottle of pyrethrin fitted with a spray attachment. This deters the ladybugs from entering the home.
