Wasp and Hornet Spray (WHA) from ACE Chemical

By ACE Chemical.

ACE's WHA features a propietary propellant and valve system that maintains consistent pressure, meaning trade pros can rely on a strong, even stream every time they spray. 

When you need to protect your home, workspace or job site from aggressive stinging insects, Wasp and Hornet Spray (WHA) from ACE Chemical gives you powerful control and peace of mind — fast. 

This EPA-registered aerosol insecticide is designed to deliver rapid knockdown and kill of wasps, hornets and yellow jackets on contact. Whether you’re dealing with a nest high above ground or unwanted activity near your entryways, WHA is tough on insects and easy to use in both indoor and outdoor environments. 

ACE’s Wasp and Hornet Spray is a Tetramethrin-based aerosol featuring a proprietary propellant and valve system that maintains consistent pressure throughout the life of the can. This means trade pros can rely on a strong, even stream every time they spray. 

A high-pressure formula delivers a powerful, non-flammable 20-foot spray stream — making it ideal for hard-to-reach nests. Once applied, it continues working with residual action to kill insects returning to the treated nest.  

Using WHA is simple and effective. For best results, spray the nest in the early morning or evening, when most insects are inside and activity is low. Always spray in still air conditions from a safe distance — never directly beneath the nest. Hold the can upright at arm’s length and first spray the nest opening, followed by a thorough coating of the rest of the nest until it is fully saturated. Insects may fall and die after treatment, and any returning later will also be eliminated. 

Wait at least 48 hours before removing the treated nest. If desirable plants are accidentally contacted during application, hose them off promptly with water.
