Mechanical means of exclusion
- Sealing ladybugs out by caulking cracks and around utility service openings, fixing broken window screens and door jams, plugging cracks in the foundation or roof as well as similar exclusion-type activities will help prevent the asian beetles from entering in the first place.
- Shady areas are less likely to attract lady bugs.
Ladybugs ( lady beetles) are beneficial insects to gardners because they are predators of garden pests like aphids and spider mites. In other words, we want lady beetles in our gardens, but if you need to control them review our lady bug control information. The problem happens when adult beetles try to enter our homes in the fall with the purpose of sheltering there until spring.
Most lady beetles head for the hills in the fall to shelter in natural cavities. A new imported species, the multicolored Asian lady beetle, likes to spend winters at lower elevations, and our houses happen to be very handy. If they gain entry they can be a pest all winter. They do no direct harm but some believe they contribute to indoor allergies and they can be very messy.
It is important to prevent them from overwintering in your homes by spraying the exterior walls during the Fall months.
- The ladybug, commonly called the Asian lady beetle is a pest as well as a beneficial insect.
- They are really only a pest by their presence.
- Ladybugs do not feed on or damage anything in the home.
- Ladybugs do not carry diseases or sting, nor can they
However, when large numbers of them take up residence in a home, they will crawl all over the walls, windows, light fixtures and any other surfaces.
Adult Asian lady beetles are oval, convex, about 1/4-inch long, and pale yellow-orange to dark orange-red. Although general body shape is usually similar, there are differences in size and coloration between ladybug species, although in the United States they are usually red or orange with black markings.
Since ladybugs are tree-dwelling insects, homes and buildings in forested areas are especially prone to infestation. Suburban and landscaped industrial settings adjacent to wooded areas also have large asian beetle aggregations.
Asian lady beetles (LadyBugs) congregate in large numbers during the late fall rather than disperse to over winter individually under bark or in leaf litter, as do most lady beetles. Asian lady beetles (LadyBugs) prefer to cluster on the sides of homes and other buildings, eventually working their way into the building through small cracks or crevices, or natural breaks in the window panes, door jams or foundations as the temperatures decrease. They are seeking a suitable place to spend the winter (over winter).
Once inside the building, ladybugs hibernate, until the first warm days of late winter or early spring, when they seem to come to life again and begin crawling about. Asian beetles tend to be attracted to lighter colored buildings and especially to those that are illuminated by the sun (typically the south or southwest side of the structure). Darker colors and buildings in the shade are less likely to have problems. After spending the winter months tucked away in a wall void or other secluded place, they have simply forgotten how they got in. When they become active in the late winter, lady bugs often find themselves inside the home rather than outside. At this time ladybugs are merely looking for a way to escape to the out-of-doors. This reawakening may take place over several weeks, depending on temperatures and the size of the population.
