Ladybugs also known as Lady Beetles are a nuisance, but there is nothing designed to use to eliminate them.  They are highly beneficial insects.  The red ones found in our area are native, all other colors are not.

The adults will overwinter starting in the autumn in protected places.  For example:  under leaves, rocks, landscape timbers and inhabit structures.  They will lay orange eggs on end in single or multiple groups of 12 on plants infested by aphids, mealybugs, scale insects, etc.  Mature larvae attach to leaves by the tip of their abdomens and pupate without forming a cocoon.

They will eat aphids, mealybugs, mites, scale insects, leafhoppers, thrips, scale insects, whiteflies and other soft-bodied insects and their eggs.  For this reason, gardeners will release the Asian Lady Beetles for biological control of aphids to avoid the chemical control.  The result of this method of aphid control has greatly increased them entering structures; like your house, your neighbors' houses...
