Asian Beetle Control (Lady Bug Control)

What do Asian Lady Beetles look like?

The Asian Lady Beetle, or “Lady Bug” is oval-shaped with a convex body, about 1/4-inch long, and pale yellow-orange to dark orange-red with black markings.

Asian Beetle Behavior

The Asian Lady Beetle usually appears in mass numbers in late fall or winter, flying or crawling inside a home or garage. This congregating behavior begins in mid October and is initiated by the first cold weather day that is followed by slightly warmer temperatures. During this warmer period, Asian lady beetles begin gathering by hundreds of thousands around homes and outside tall, light-colored buildings where they may appear first on the southwest side facing wooded areas.

How to Get Rid of Asian Beetles

Once these lady beetles establish residence inside your home, there is little that can be done to treat them aside from vacuuming up those that are visible. The better option is to prevent them from entering your home in the first place. We recommend a control program that begins the first week in October (if possible) while Asian lady beetles are just beginning to congregate and before they enter your home. A combination of the following preventative treatments will work best.

1. Perimeter Treatments-Using a perimeter treatment on the outside and inside of your home in early October creates a pesticide barrier to control Asian lady beetles and will prevent them from entering. Demand CS and Suspend SC are both excellent perimeter products that leave a long lasting residue. Spray Demand or Suspend in a continuous band around the entire perimeter, including attic vents, eaves, windows, doors, siding, and any other possible points of entry, especially areas where the asian beetles are prolific. To assure lasting control of Asian lady beetles and other similar pests, repeat treatment using a garden sprayer such as the Chapin Premier Sprayer every couple of months throughout fall and winter.
   
2. Wall Void Treatments - Apply Delta Dust with a hand duster into wall voids by dusting under baseboards, around electrical outlets and switch plate covers, and inside plumbing openings as a secondary form of perimeter control to keep Asian lady beetles out.
   
3. Sealing Entry Points - For added protection, you can “seal out” Asian lady beetles and other similar pests to a large degree by caulking cracks around utility openings, fixing broken doors and window screens, plugging cracks in siding or roofing, and performing other similar exclusion activities.
