Lady Beetles are almost entirely beneficial insects because they feed on harmful insects.
But can become a nuisance pest because of their overwintering behavior.
Insects that overwinter inside as adults can cause a lot of grief to homeowners and commercial supervisors.
The Lady Bug must overwinter in a suitable site that is protected from the elements.
The Lady Bug or Lady beetle is only one of the dozen or so of overwintering insects.
They will generally only become pests over the fall, winter, and spring months when the nights become cooler and this signals that it is time to overwinter.
The Lady bug or Lady Beetle will start being attracted to the warmer sides of the structure, where the sun will heat it the greatest.
The south and the west side should be treated with a residual insecticide in early fall to control as many of the lady bugs before they make their way inside in large numbers.
They will crawl up and into any crack and crevice and any space that will allow entry into the warm home. Applying a crack and crevice aerosol will also be very effective in controlling them.
