How to Get Rid of Asian Lady Beetles (and the Beetles Often Mistaken for Them)

Asian beetle pest control starts with confirming what you have. Asian lady beetles gather on sunny walls and windows in fall. Carpet beetles live indoors and feed on wool, fur and pet hair. Vacuum live beetles instead of crushing or spraying them, and clean up carpet beetle food sources. Then seal the cracks and gaps where they enter. That order keeps you from wasting money on the wrong spray.

Key Takeaways

• A beetle crawling across carpet in a desert home may be a carpet beetle, not an Asian lady beetle.
• Vacuuming beats crushing or indoor spraying, which can stain walls and misses beetles hiding in voids.
• Sealing cracks and gaps outside is the lasting fix, and sprays only support that exclusion work.

Is it an Asian lady beetle, a carpet beetle or something else?

Check the head and check the carpet. An Asian lady beetle is rounded and orange to red, with a black M- or W-shaped mark behind the head. Penn State Extension's profile of the multicolored Asian lady beetle notes that its color and spot count vary widely, so that mark is the reliable sign.

Carpet beetles are small, oval adults, but their larvae give them away. The UC Statewide IPM Program's carpet beetle guide describes larvae covered in dense bristles that feed indoors on wool, fur and other animal-based materials. Lady beetles do not do this.

Why do beetles end up inside West Valley homes?

Asian lady beetles come in looking for a place to overwinter. Carpet beetles come in, or stay in, because a home holds their food. According to the University of Kentucky Department of Entomology's guidance, Asian lady beetles gather on sunny, light-colored exterior walls in fall, then slip through cracks and gaps.

Many homes in Surprise have light stucco walls facing full sun, and that is the surface the Kentucky sheet describes. Carpet beetles follow a different pattern. They breed wherever lint, pet hair, wool rugs or stored clothing collect, so a sighting in a closet points to food inside, not to a fall invasion. Our guide to year-round pests in Surprise covers how local pest activity shifts through the seasons.

Patrick's Home Solutions has served West Valley homes since 2016 under Arizona license #9794. Most beetle calls come down to one question we answer first: which beetle is it?

What is the best way to clear beetles that are already inside?

Vacuum them. For Asian lady beetles, a vacuum removes the cluster without crushing them. Crushed beetles release a yellow fluid that stains walls and smells. For carpet beetles, thorough vacuuming and cleaning remove both the larvae and the food they live on.

1. Slip a knee-high stocking into the vacuum hose, secure it with a rubber band, and vacuum lady beetles off walls and windows.
2. Empty the stocking or bag outside, away from the house.
3. For carpet beetles, vacuum rug edges, under furniture, closet floors and heat registers where lint and hair build up.
4. Launder or dry-clean wool, fur and stored clothing, and throw out items the larvae have chewed through.
5. Watch for new activity over the following weeks, and note where the beetles show up.

What can you spray and seal outside to keep beetles from coming back?

Sealing does more than spraying. The EPA's do's and don'ts of pest control lists sealing cracks and openings and removing food, water and shelter as the safest first steps before using pesticides. A perimeter treatment on sunny walls before fall can support that work.

Check these points on the sunny sides of the house first:

• Gaps around window and door frames, and worn weatherstripping
• Openings where pipes, cables and AC lines enter the wall
• Gaps at eaves, soffits and roof edges
• Torn or missing screens on attic and wall vents

Caulk small cracks and replace weatherstripping and screens. For a full job, our Home Seal service closes the gaps that let beetles, scorpions and other pests inside.

Which insecticides work on beetles, and which should you skip?

No indoor spray fixes an Asian lady beetle problem. The useful product is an exterior residual labeled for beetles, applied to entry areas before they gather. For carpet beetles, cleaning comes first and targeted treatment second. Under federal law the label is the law, so any product goes only where its label allows.

Penn State Extension's guide to integrated pest management combines sealing, sanitation and targeted treatment to use as little pesticide as possible.

Skip these:

• Aerosol sprays on clusters indoors. They leave dead beetles and stains, and they miss the beetles in wall voids.
• Total-release foggers. They coat open surfaces, not the cracks where beetles hide.
• Soaking carpets with spray before cleaning. Larvae protected by lint and hair survive.

When should you call a pro, and what affects the cost of treatment?

Call a pro when beetles keep returning after you vacuum and seal, when you cannot reach high eaves, or when carpet beetle damage keeps spreading. The cost depends on home size, how many entry points need sealing, the beetle type, and whether you choose a one-time visit or a recurring plan.

Before you hire anyone, check two things:

• A license and proof of insurance, which the EPA's tips for selecting a pest control service advise asking for
• Written treatment plans, product names and estimates you can compare, as Penn State Extension's advice on choosing a pest management company recommends

Frequently Asked Questions

What makes Asian lady beetles go away?

Removing the live beetles and closing their way in makes them go away. Vacuum clusters instead of crushing them, then seal cracks around windows, doors, vents and utility lines on the sunny walls. A labeled exterior treatment applied before fall can reduce how many beetles gather there.

How long does the Asian beetle infestation last?

Asian lady beetles arrive in fall to overwinter. Some stay hidden in walls and attics until warm weather returns, and they may appear indoors on warm days before then. Carpet beetles differ. They breed indoors, so they persist until you remove their food sources.

What smell do Asian beetles hate?

No scent has been shown to reliably keep Asian lady beetles out. Home remedies based on smell are unproven. Sealing entry points and vacuuming the beetles you find inside work better than any odor you might spread around.
