Pest Identification: Ladybugs

As temperatures fluctuate in the fall, ladybugs seek shelter for winter, often in buildings and homes. They are drawn to lighter colors and typically enter through cracks in soffits or loosely fitting windows and doors. They leave a scent to signal others to a suitable location. Ladybugs don't fly below 55 degrees Fahrenheit but can travel long distances to find high elevation wintering spots. 

Inside buildings, they tend to hide in groups in concealed areas to overwinter, surviving on stored fat. In fluctuating temperatures or as spring nears, indoor lights may confuse them, causing aimless flying and eventual death if they can't find an exit. When disturbed, ladybugs can release a yellowish fluid with an unpleasant odor from their legs, which can stain household items. 

Similar overwintering habits are seen in Western Conifer Seed Bugs, Stink Bugs, and Cluster Flies. 

To manage these insects, it's crucial to identify and seal entry points to prevent future entry. Once indoors, a vacuum cleaner can effectively capture them. Indoor use of insecticides is not recommended as dead insects can attract other pests like larder and carpet beetles. The best prevention is a chemical barrier (traditional or organic) applied externally to the building or home in the fall, particularly in August and early September, as part of a Fall Invader Program. 

Ladybugs are considered an Occasional Invader, the best time to treat them is early Fall (mid-August to early September) with our Fall Invader Program. Once they get in, they are in. Please call Ford's Hometown Services for a quote.
