For Asian lady beetles entering a home, the two Harris sprays are the most directly relevant options: the gallon is suited to repeated applications, while the 32-ounce bottle is a smaller format. Tempo SC Ultra is a broader crawling-insect concentrate, and Pestie is a home barrier kit for other listed pests. Bonide targets Japanese beetles on plants, a different beetle problem. Check each product label for approved pests, application sites, and safety directions.

| Pestie Home Barrier Kit | DIY home pest barrier | Kit lists ants, cockroaches, and spiders |
| Bonide Japanese Beetle Spray | Japanese beetles on plants | Ready-to-use garden and residential spray |
Harris Asian Lady Beetle Killer, Gallon
This liquid spray is the most directly targeted choice in this selection for Asian lady beetles. Its listed features say it kills after the spray has completely dried and continues to kill for weeks after application. The formula is described as odorless and non-staining when used according to label directions.
Best for: Households that need a larger supply for repeated applications. The one-gallon container is intended for ongoing use, making it a better fit than a smaller bottle when multiple treatments may be needed.
Limitation: The stated kill occurs after the product dries, not immediately on contact. Follow the label for where and how to apply it, and keep people and pets away as directed.
Harris Asian Lady Beetle Spray, 32 Ounces
This smaller Harris bottle is a direct option for Asian lady beetles and box elder beetles. Like the gallon version, it is described as odorless and non-staining when used according to its directions. The listed residual effect begins after the spray dries and may continue for weeks.
Best for: Buyers who want the targeted Harris formula in a smaller quantity or expect to treat a more limited area. Choose it over the gallon if a large supply is not needed.
Limitation: The product is not available for sale in California, according to the listing. It also does not provide an immediate-dry kill; the stated effect occurs once the application is completely dry.
Tempo SC Ultra Insecticide Concentrate
Tempo SC Ultra is a liquid concentrate described for broad-spectrum control of ants, spiders, and other nuisance crawling insects. The listed directions describe indoor and outdoor structural or perimeter applications, including foundations, doorways, patios, garages, basements, and entry points. It must be diluted according to its label.
Best for: Buyers seeking a multipurpose perimeter treatment for listed crawling pests, rather than a product specifically marketed for Asian lady beetles. It was selected as a broader home-treatment alternative.
Limitation: Asian lady beetles are not named in the supplied product features. Do not assume it is appropriate for that pest or for a particular surface; verify the label before use.
Pestie Home Barrier Pest Control Kit
Pestie is a do-it-yourself home barrier kit whose listed target pests include cockroaches, ants, and spiders. The product information says one set covers homes up to 4,500 square feet and includes measured components and step-by-step instructions for application.
Best for: Homeowners looking for a guided kit to address the pests named in its listing. It is a different kind of option from a beetle-specific spray, so consider it only when its stated target pests match the household’s needs.
Limitation: Asian lady beetles are not listed among the product’s stated targets. The coverage figure does not establish that the kit controls beetles; check the label for approved pests and sites.
Bonide Japanese Beetle Killer Spray
Bonide is a ready-to-use spray listed for Japanese beetles and several other garden pests, including aphids, leafhoppers, caterpillars, and stink bugs. Its stated use includes vegetables, flowers, ornamentals, trees, shrubs, and residential indoor, outdoor, or greenhouse settings.
Best for: Gardeners managing Japanese beetles or the other named plant pests. It is included as a beetle-related option, but Japanese beetles and Asian lady beetles are distinct pests.
Limitation: The supplied features do not identify Asian lady beetles as a target. Choose a product whose label specifically supports the pest and application site you need.
Buying Guide: How To Choose An Asian Beetle Spray
Is the target Asian lady beetles or Japanese beetles?
Identify the pest before choosing a spray. Asian lady beetles commonly become a household nuisance, while Japanese beetles are often treated as plant pests. A product labeled for one should not automatically be treated as effective for the other. Of these options, the Harris sprays explicitly name Asian lady beetles.
Do you need a ready-to-use spray or a concentrate?
The Harris and Bonide products are described as sprays, while Tempo SC Ultra is a liquid concentrate that must be diluted according to its label. A ready-to-use format avoids measuring and mixing. A concentrate may suit buyers planning a broader treatment, but preparation and application must follow label directions.
How much product should you buy?
Choose the Harris 32-ounce bottle for a smaller quantity and the gallon for repeated applications. The listed features do not specify how many treatments either container provides, since coverage depends on the application. Avoid buying by container size alone; consider the labeled treatment area and intended frequency.
What safety and application details matter?
Read the full product label before use, including approved indoor or outdoor sites, target pests, dilution requirements, drying time, and precautions for people, pets, and surfaces. The Harris formula is described as non-staining when used according to directions, but that is not a reason to skip label instructions or test an inconspicuous area when appropriate.

Does the Harris spray kill Asian lady beetles immediately?
The supplied product information says it kills once completely dried and continues to kill for weeks after application. It does not describe an immediate wet-spray kill.
Can Japanese beetle spray be assumed to work on Asian lady beetles?
No. Japanese beetles and Asian lady beetles are different pests. Check the product label for the specific target insect before applying a product.
Is Tempo SC Ultra listed specifically for Asian lady beetles?
No. Its supplied features describe broad crawling-insect control and name ants, spiders, and other nuisance pests, but do not name Asian lady beetles.
