Asian Beetles
Foggers Pest Control is Central Minnesota's trusted choice for Asian beetle control.
Are Asian lady beetles swarming your windowsills, porch lights, or siding this season?
Asian lady beetles (sometimes called “Asian beetles”) are an invasive nuisance pest that often gathers on sunny sides of homes in the fall and can sneak indoors through small gaps. Once inside, they commonly show up around windows, ceilings, and light fixtures, and they can leave stains and create an unpleasant odor when disturbed. Homeowners want to control them to reduce swarming, prevent indoor invasions, and keep their home comfortable and pest-free.
Why Professional Asian Beetle Control Matters
Asian lady beetles can become a major nuisance when they gather on the outside of a home and make their way indoors in large numbers. Once inside, they often collect around windows, ceilings, and light fixtures, and they can leave stains and create an unpleasant odor when disturbed. In some cases, they may also trigger irritation or allergic-type reactions for sensitive individuals.
Foggers Pest Control uses proven inspection and treatment methods to help reduce Asian beetle activity and limit indoor invasions. Our technicians focus on the areas these pests use to gather and enter, helping minimize indoor encounters and keep your home more comfortable throughout the season.


How to Tell if You Have an Asian Beetle Problem
A common sign is seeing clusters of orange or reddish “lady beetle-looking” insects gathering on sunny sides of your home, especially around windows, doors, soffits, and siding in the fall. They often show up on warm afternoons and may collect near porch lights or other bright areas.
If they get indoors, you’ll typically find them near windows, light fixtures, ceilings, curtains, and corners of rooms. You may also notice small yellowish stains on walls or fabrics and an unpleasant odor when they’re disturbed or crushed.
FAQ's About Asian Beetles
What are Asian beetles and how can I identify them around my home?
Asian beetles, commonly called Asian lady beetles, are small, dome-shaped insects often orange to red with variable black spots; they can also be pale or nearly spot-free. Adults are about 5–8 mm long, sometimes gather in clusters on walls or windows in cool months, and emit a yellowish fluid with a noticeable odor when disturbed.
Why do Asian beetles come into houses, and when are they most likely to appear?
They seek sheltered overwintering sites as temperatures drop, entering homes through gaps around windows, doors, vents, and siding. They are most commonly noticed in late fall as they aggregate and in early spring when they become active again.
What problems can Asian beetles cause for homeowners?
They can become a nuisance by clustering on walls, windows, attics, and eaves, leaving stains from their defensive secretions on fabrics or painted surfaces, and occasionally biting if handled, which may cause mild irritation for some people.
What non-chemical steps can I take to prevent or reduce infestations?
Seal entry points such as gaps around windows, doors, utility penetrations, and screens; install door sweeps and weatherstripping; repair or replace torn screens and damaged siding; reduce outdoor lighting at night; and vacuum clusters indoors and release or dispose of them promptly.
When should I contact a pest control professional, and what should I expect from service?
You should contact a professional if Asian beetles are showing up in large numbers, spreading into living areas, or returning year after year. During service, a technician will inspect your home and apply targeted treatments as needed to help reduce activity and limit future invasions.
