HARRIS HBXA-128 Asian Lady Beetle & Box Elder Killer Spray, 1 Gallon

Highlights

The odorless formula keeps pest treatment practical around common household areas. HARRIS HBXA-128 is a one-gallon liquid spray made to kill Asian lady beetles, Japanese beetles, box elder bugs, and other insects. Its residual action continues after the treated surface dries, helping address recurring activity. The included trigger sprayer lets you apply it directly to areas where insects gather.

The formula contains deltamethrin and is described as non-staining when used according to label directions. Its 128 fluid ounces support repeated applications, making this gallon format useful for treating several locations around a home rather than focusing on a single small spot. Harris lists it as EPA-registered for indoor and outdoor use under No. 3-11. Treated areas must dry fully before children or pets return.

Buyers often praise its effectiveness against box elder bugs and Asian beetles, as well as its odorless formula. Feedback is more mixed on the sprayer and whether residue is visible on surfaces. Follow the label directions for the surface being treated, particularly when applying near windows or other visible areas.

Best use cases

Use the spray around door and window frames, window screens, baseboards, storage areas, and exterior walls where insects crawl, rest, or congregate. South-facing exterior walls are among the suggested treatment areas for lady beetles and box elder bugs. This targeted approach suits homes where activity appears around entry points or along particular walls. Compared with a small, occasional spot treatment, the gallon format is geared toward covering multiple areas and making repeat applications as needed.

The formula also targets flies, mosquitoes, and other insects, so it can serve for more than one type of pest. For screens, remove them before spraying and let them dry before reinstalling. Direct sunlight can break down the residual product more quickly, so check treated south-facing walls after a few weeks and reapply if insect activity returns.

How to use it

Remove the lid and attach the included trigger sprayer, then turn the nozzle to the “on” position. Hold the container upright and spray from approximately 12 inches away. Apply until the surface is slightly moist, without letting the product run or drip. Treat the areas where insects tend to gather, following the product label for the surface and location.

Allow treated surfaces to dry completely—approximately two hours—before children or pets return to the area. The residual formula continues to kill insects for several weeks after drying. Use the label directions as your guide for application and reapplication. Shipping restrictions apply in California and Connecticut.

Is it worth it?

This gallon is a practical fit for people dealing with recurring insect activity across several indoor or outdoor locations. The odorless formula, included trigger sprayer, and residual action make it suited to treating common gathering points and returning to them when activity resumes. Its larger volume supports ongoing applications, while the targeted spray method helps focus treatment on frames, screens, baseboards, and exterior walls. Choose it for a household pest-control routine centered on these areas and the insects named on the product.
