Multicolored Asian Lady Beetle is invading homes throughout many parts of the United States. This beetle is present in large numbers on landscape plants. The Multicolored Asian Lady Beetle is a helpful predator during the year because of its predation on aphids and other pests and thus found in large numbers on landscape plants. However, during this time of the year many homeowners look for ways to control this insect. The lady beetles vary in different shades of yellow, orange or red, either with or without black spots on the wing covers.
What triggers these beetles to begin invading homes (looking for a place to overwinter) is usually the passing of a cold front that produces heavy rain followed by clearing skies and a frost. Generally, this weather pattern is followed by a warming trend, which triggers these beetles to seek shelter.
Weatherproofing your home by sealing cracks around windows and installing tight fitting door sweeps. If heavy infestations get into the home vacuuming and then sealing and disposing the bag is an effective means of removing the beetles. Exterior insecticide application to the house from middle of October to early November may also help keep the Multicolored Asian Lady Beetle from infesting your home.
