A strong Asian beetle spray should identify Asian lady beetles on its label and match the way you plan to treat them, whether that means a gallon for repeat applications or a smaller ready-to-use bottle. Harris Asian Lady Beetle Killer stands out for its odorless, non-staining gallon formula and stated residual kill that continues for weeks after application. The other options include plant-based contact sprays, a kit with concentrate refills, and broader home insecticides that also list Asian lady beetles or beetles among their targets.
Compare the target pests, volume, and application format before choosing: these products are not interchangeable, and label directions determine where and how each may be used. The picks below prioritize explicit Asian beetle relevance, then practical specifications and included components.
Harris Asian Lady Beetle Killer is the leading choice for buyers seeking a product explicitly named for Asian lady beetles and supplied in a gallon for repeated applications. Its odorless, non-staining formula is described as continuing to kill Asian lady beetles for weeks after application once the spray has dried. For a plant-based contact spray in a smaller container, EcoPest is a more targeted alternative; it lists clove and cottonseed oils and a 22-fluid-ounce aerosol format.

Detailed Reviews: Best Bug Spray For Asian Beetles
#1 · Best Overall
1. Harris Asian Lady Beetle Killer
- Form: Spray
- Weight: 8.8 lb
Best for: Large-Volume Residual Treatment.
Why it ranks #1: Names Asian lady beetles directly and comes in a gallon; its odorless, non-staining formula is described as continuing to kill for weeks after drying.
A one-gallon supply supports repeated applications, while the formula continues killing Asian lady beetles for weeks after it dries. That combination suits homeowners addressing recurring seasonal arrivals who want to treat areas more than once without choosing an odorless, non-staining spray that can damage fabrics when used according to label directions.
The extended residual formula keeps working for weeks after drying, so one application can continue killing Asian lady beetles beyond the initial spray. Its gallon volume also provides material for repeated applications during an ongoing infestation. Harris describes the formula as odorless and non-staining, with fabric use subject to label directions, which can make indoor treatment more convenient. The product also lists Japanese beetles and box elder bugs among its targets, giving it uses beyond Asian lady beetles.
- Continues killing Asian lady beetles for weeks after drying
- One gallon supports repeated applications
- Odorless formula
- Non-staining when used according to label directions
- The spray must dry completely before it kills.
Skip it if you need immediate knockdown before surfaces dry; EcoPest Boxelder Bug & Asian Lady Beetle Spray is described as killing by contact.
Choose this gallon for recurring Asian lady beetle problems when repeated treatment and weeks of post-drying activity matter. It also targets Japanese beetles and box elder bugs; allow for the stated drying-dependent kill and follow label directions around fabrics.

2. EcoPest Beetle Spray
- Form: Aerosol
- Volume: 22 fluid oz
Best for: Plant-Based Contact Spray.
Why it ranks #2: Specifically targets Asian lady beetles with clove and cottonseed oils in a 22-fluid-ounce aerosol; the listed tests report contact mortality within 30 minutes.
Clove oil and cottonseed oil give this 22-fluid-ounce EcoPest aerosol a plant-based formula for indoor and outdoor use. Its contact-kill positioning suits buyers who want to target Asian lady beetles and boxelder bugs on home surfaces, with the listed non-staining formulation intended for doors, windows, siding, and baseboards.
The aerosol is listed for indoor and outdoor use, making it applicable to the home entry points named in the title, including doors, windows, siding, and baseboards. Its clove-oil and cottonseed-oil ingredients distinguish it from conventional formulas, while the product states that it kills the listed pests by contact. The supplied test information reports mortality within 30 minutes for adult Asian lady beetles and adult and nymph-stage boxelder bugs; the 22-ounce volume suits targeted rather than gallon-scale applications.
- Plant-based clove-oil and cottonseed-oil ingredients
- Listed for indoor and outdoor use
- Non-staining formulation
- Targets Asian lady beetles and boxelder bugs by contact
- The 22-ounce container offers less volume than a gallon-size treatment.
Skip it if you need gallon-scale supply for repeated applications; Harris Asian Lady Beetle and Box Elder Killer is sold in a gallon.
This EcoPest spray fits buyers seeking a plant-based, indoor-and-outdoor contact treatment for Asian lady beetles and boxelder bugs. Its 22-ounce container is better suited to targeted home use than to stocking a gallon for repeated applications.

#3 · Largest Plant-Based Spray
3. Colton's Naturals Control Spray
- Form: Aerosol
- Weight: 2 lb
- Volume: 32 fluid oz
Best for: Entry-Point Targeted Treatment.
Why it ranks #3: Directly names Asian lady beetles and offers a 32-fluid-ounce plant-based aerosol for indoor and outdoor use on appropriate water-safe surfaces.
Colton’s Naturals targets visible insects and infested surfaces directly, making its 32-fluid-ounce spray a practical option for seasonal invaders around windows, doors, siding, baseboards, and eaves. The plant-based formula is listed for indoor and outdoor use, so treatment can follow the locations where beetles gather or enter.
Direct application is the central workflow: spray visible boxelder bugs and Asian lady beetles, as well as infested surfaces, for fast-acting contact control. The listed entry-point locations—windows, doors, siding, baseboards, and eaves—help focus treatment around common gathering and access areas rather than treating indiscriminately. Its plant-based formula is described for indoor and outdoor use on appropriate water-safe surfaces. The 32-fluid-ounce aerosol provides a larger stated volume than a 22-ounce container for targeted home applications.
- Fast-acting contact control on directly sprayed insects
- Treats infested surfaces
- Listed for indoor and outdoor use
- 32-fluid-ounce container
- Contact control requires spraying the visible insects or infested surfaces directly.
Skip it if you want a spray described as continuing to kill for weeks after drying; Harris Asian Lady Beetle and Box Elder Killer lists that residual activity.
Colton’s Naturals suits homeowners targeting visible seasonal beetles at windows, doors, siding, baseboards, or eaves. Its use depends on direct application, and the listed indoor treatment is limited to appropriate water-safe surfaces.

4. Enforcer Bug Max
- Form: Spray
Best for: Gallon Multi-Pest Coverage.
Why it ranks #4: The ready-to-use 128-ounce gallon lists Asian lady beetles among its targets and contains 0.03% deltamethrin for broad home pest control.
A ready-to-use gallon pairs Asian lady beetles with a broad listed pest roster, including bed bugs, brown recluse spiders, and black widow spiders. That makes Enforcer Bug Max relevant to households seeking one home-pest spray for several named targets, without needing to prepare a concentrate before application.
The 128-ounce, ready-to-use format removes the mixing step and gives buyers a gallon of spray for home pest control. Its listed target range includes Asian lady beetles alongside bed bugs and two named spiders, plus German cockroaches, carpenter ants, and carpenter bees, making the product useful when more than one pest is in scope. The up-to-one-year claim applies specifically to German cockroaches, not to Asian lady beetles, so buyers should distinguish that duration from the broader target list.
- Ready-to-use gallon format
- Lists Asian lady beetles among its targets
- Also lists bed bugs and named spiders
- Up-to-one-year German cockroach kill claim
- The up-to-one-year duration claim applies to German cockroaches, not Asian lady beetles.
Skip it if you need a product with stated weeks-long residual kill for Asian lady beetles; Harris Asian Lady Beetle and Box Elder Killer specifies that duration.
Enforcer fits buyers who want a ready-to-use gallon for Asian lady beetles and several other listed household pests. Treat the duration claim narrowly: its stated up-to-one-year protection is for German cockroaches, not Asian lady beetles.

5. Mysora Lady Beetle Spray Kit
- Weight: 1.3 lb
- Volume: 16 fluid oz
Best for: Refillable Peppermint Oil Kit.
Why it ranks #5: Its title names Asian lady beetles, and the kit combines a 16-ounce ready-to-use bottle with two 1-ounce concentrates and plant-based oils.
A ready-to-use 16-ounce bottle comes with two one-ounce concentrates, giving this Mysora kit a refill path after the initial spray is used. Its peppermint-oil and clove-oil formula is listed for indoor and outdoor use, suiting buyers who want a plant-based option for recurring home treatments.
The kit pairs a ready-to-use bottle for immediate application with two concentrated refills, allowing the spray bottle to be refreshed multiple times rather than relying on the initial fill alone. Its listed active ingredients are 4% peppermint oil and 1% clove oil, supporting buyers seeking a plant-based formula. The product is described for indoor and outdoor use and names Asian lady beetles, Japanese beetles, and box elder bugs, making it relevant to several beetle-control needs around the home.
- Includes a 16-ounce ready-to-use spray bottle
- Includes two one-ounce concentrate refills
- Contains 4% peppermint oil and 1% clove oil
- Listed for indoor and outdoor use
- The concentrated refills require refreshing the spray bottle rather than providing additional ready-to-use bottles.
Skip it if you prefer a single ready-to-use aerosol without mixing or refilling; Colton's Naturals Boxelder Bug & Asian Lady Beetle Control Spray comes as a 32-ounce aerosol.
Pick this kit if you want a plant-based spray with concentrate refills for continued indoor or outdoor treatment of named beetles. It suits buyers comfortable refreshing the bottle; keep the listed active ingredients and use directions in mind.

6. BASF PT Fendona
- Form: Spray
- Weight: 1.5 lb
Best for: Crack-and-Crevice Spot Treatment.
Why it ranks #6: This pressurized spot-treatment insecticide lists beetles and stinkbugs, but the supplied target-pest details do not specifically identify Asian lady beetles.
BASF PT Fendona is specified for spot or crack-and-crevice application, giving buyers a focused treatment method for Asian lady beetles and other listed insects. Its 17.5-ounce pressurized spray also names beetles, stinkbugs, ants, spiders, and wasps, making it relevant to targeted pest control rather than general surface spraying.
The spot-treatment direction helps narrow application to selected locations, while the crack-and-crevice option supports treating the gaps named in the product instructions. Its pest list includes beetles and stinkbugs alongside ants, bed bugs, crickets, spiders, earwigs, fruit flies, moths, ticks, and wasps, offering utility for multiple listed targets. The pressurized 17.5-ounce container is a compact spray format for focused work. The listing states that sale is not available in California, which is a purchase restriction for residents there.
- Specified for spot treatment
- Specified for crack-and-crevice treatment
- Lists beetles and stinkbugs among its targets
- Pressurized 17.5-ounce spray
- The listing excludes sale in California.
Skip it if you live in California; this product is listed as unavailable for sale there.
BASF PT Fendona suits buyers seeking a pressurized spray for targeted spot or crack-and-crevice treatment of beetles and other listed pests. It is not an option for California residents, and the specified application is focused rather than broad-area.

View on AmazonWhy beetles can return after a spray
A contact spray can kill visible beetles without preventing new ones from entering, so treat it as one part of a control plan rather than a guarantee of lasting exclusion. Colton’s Naturals Control Spray describes fast-acting contact control when sprayed directly on insects and infested surfaces. EcoPest likewise describes contact action, while Harris Asian Lady Beetle Killer specifically claims residual kill for weeks after the spray dries.
These are different claims: a product that works on insects it reaches may not keep later arrivals from appearing. Focus treatment on the entry points and infested surfaces allowed by the product label, and check those areas again after application.
If beetles keep appearing, identify and address likely entry routes rather than repeatedly spraying beyond label directions. The products here do not establish that any spray permanently prevents reinfestation.
Match the spray format to the treatment area
The main format trap is choosing a large container for a small spot treatment or expecting a small aerosol to cover repeated, broad applications. Harris Asian Lady Beetle Killer and Enforcer Bug Max are both supplied in gallon formats, but Harris specifically describes repeated applications and residual kill for Asian lady beetles. EcoPest comes as a 22-fluid-ounce aerosol, Colton’s Naturals Control Spray as a 32-fluid-ounce aerosol, and Mysora Lady Beetle Spray Kit includes a 16-ounce ready-to-use bottle plus two 1-ounce concentrates.
BASF PT Fendona is pressurized and specified for spot or crack-and-crevice treatment. Volume alone does not show coverage, and a concentrate is not the same as a ready-to-use spray.
Check the label for dilution, suitable surfaces, and application locations before assuming one format fits your home.
How to Choose an Asian Beetle Spray
Target pest and duration
Look for Asian lady beetles named explicitly when that is the pest you need to control. Harris Asian Lady Beetle Killer identifies them in its title and claims continued kill for weeks after the spray dries; EcoPest Beetle Spray and Colton’s Naturals Control Spray also name them directly, with contact-control descriptions. Enforcer Bug Max lists Asian lady beetles among several target pests, while BASF PT Fendona lists beetles without specifying Asian lady beetles in the supplied details.
If you want a product with a stated residual claim, Harris is the clearest match here. If you intend to treat visible insects directly, the contact-spray descriptions on EcoPest and Colton’s may better match that use.
Container size and refill setup
Choose a container size that suits the area and frequency of application you expect, while following its label. The listed sizes range from Mysora Lady Beetle Spray Kit’s 16-ounce ready-to-use bottle to gallon formats from Harris Asian Lady Beetle Killer and Enforcer Bug Max. EcoPest Beetle Spray is 22 fluid ounces, Colton’s Naturals Control Spray is 32 fluid ounces, and Mysora adds two 1-ounce concentrates for refilling its bottle.
A gallon may suit someone planning repeated applications, while a smaller aerosol may be easier to handle for targeted treatment. The concentrate kit offers replenishment, but check the product instructions for how to prepare it; do not assume concentrate is ready to spray.
Ingredients and application format
Compare the listed ingredients and spray format with the surfaces and treatment locations permitted by the label. EcoPest Beetle Spray lists clove and cottonseed oils, and Mysora Lady Beetle Spray Kit lists 4% peppermint oil and 1% clove oil. Colton’s Naturals Control Spray is described as plant-based and for indoor and outdoor use on appropriate water-safe surfaces.
By contrast, Enforcer Bug Max lists 0.03% deltamethrin, and BASF PT Fendona is a pressurized insecticide specified for spot or crack-and-crevice treatment. If a plant-based formulation matters to your choice, compare EcoPest, Colton’s, and Mysora.
If you need the listed crack-and-crevice format, BASF is the distinct option; verify label directions and restrictions before use.
Which Asian Beetle Spray Should You Choose?
For a specifically named Asian lady beetle product with a gallon of spray and a stated residual claim, choose Harris Asian Lady Beetle Killer. For a smaller plant-based contact spray, EcoPest Beetle Spray offers a 22-fluid-ounce aerosol and lists clove and cottonseed oils; Colton’s Naturals Control Spray gives you 32 fluid ounces and describes indoor and outdoor use on appropriate water-safe surfaces. If you want a ready-to-use gallon with Asian lady beetles among several listed pests, consider Enforcer Bug Max.
Mysora Lady Beetle Spray Kit suits shoppers who want a smaller bottle plus two concentrate refills. BASF PT Fendona is the least specific match: it lists beetles and stinkbugs and is designed for spot or crack-and-crevice treatment, but does not name Asian lady beetles in the supplied details.
Follow each product label.

Frequently Asked Questions
How should I apply spray around windows and other Asian beetle entry points?
Follow the product label for approved surfaces, application method, and precautions. Apply only where the label permits; do not assume every spray is suitable for window frames, siding, or other surfaces. The supplied details describe Colton’s Naturals for indoor and outdoor use on appropriate water-safe surfaces, while BASF PT Fendona is for spot or crack-and-crevice treatment.
How can I keep Asian lady beetles from returning after spraying?
Use the spray only as directed, and address entry points as part of your prevention plan. Check window and door screens and seal gaps where practical. Harris is described as continuing to kill Asian lady beetles for weeks after application once dry, but that residual claim does not replace label directions or entry-point maintenance.
Are plant-based sprays appropriate to use around pets and children?
Plant-based ingredients alone do not establish that a spray is safe in every situation. Check the specific product label for precautions, approved locations, and when people or pets may re-enter treated areas. EcoPest lists clove and cottonseed oils, while the supplied product title describes it as child- and pet-safe; follow its label.
Which option is suited to repeated applications?
Harris is the clearest fit if you want a product explicitly named for Asian lady beetles in a gallon format. Its supplied description also states that the odorless, non-staining formula continues killing Asian lady beetles for weeks after application once dry. Follow the label for application frequency and directions.
Which products specify indoor and outdoor use or treatment areas?
Colton’s Naturals describes indoor and outdoor use on appropriate water-safe surfaces. BASF PT Fendona is described for spot or crack-and-crevice treatment, but its supplied details name beetles and stinkbugs rather than Asian lady beetles. Check each label to confirm whether the intended location and surface are permitted.
Final Words
For a product explicitly named for Asian lady beetles, Harris is the leading choice when a gallon format and stated residual claim suit your needs. EcoPest is the more targeted alternative for a smaller plant-based contact spray; Colton’s Naturals offers a larger spray described for indoor and outdoor use on appropriate water-safe surfaces. Consider Enforcer or Mysora for their stated formats, while BASF is a less specific match.
Follow the product label.
