Description

When stinging insects move in, you need more than a temporary fix. You need a fast, effective way to stop the problem at the source.

Final Hex is a plant-powered wasp and hornet spray designed for rapid knockdown and decisive nest treatment. This alcohol-based aerosol targets paper wasps, hornets, yellowjackets, and mud daubers on contact, helping you act quickly before they can regroup, scatter, or defend the nest.

The high-output stream reaches up to 15 feet, so you can treat nests from a safer distance around decks, patios, siding, eaves, wall voids, and other hard-to-reach outdoor areas. Its 360-degree actuator sprays at any angle — even upside down — making it easier to hit hidden nests with confidence and precision.

Powered by geraniol and sodium lauryl sulfate, Final Hex is a FIFRA 25(b) minimum-risk formula that delivers strong performance with a plant-powered approach. The CO₂ bag-on-valve system keeps the propellant separate from the formula, so there’s no shaking required before use and nearly every drop can be put to work.

For best results, apply at dawn or dusk when colonies are least active. Stand upwind, saturate the nest and entry point, and let Final Hex do the rest.

Frequently asked questions

If you don't see the answer to your question, contact us!

Can Final Hex be used indoors?

Final Hex will work against wasps - wherever they live. However, this was primarily intended for use outdoors. Indoor use may be appropriate if a stinging insect nest is located inside a structure such as a shed or garage. Always follow label instructions and ensure adequate ventilation.

Is Final Hex safe to use around my home?

Final Hex is a FIFRA 25(b) minimum-risk insecticide, but it should still be used responsibly. Avoid direct contact with people and pets during application, and follow all label directions. Keep children and pets away from treated areas until the application has dried or settled.

How quickly will I see results?

In most cases, stinging insects will be knocked down quickly and die shortly after being sprayed. When the nest is properly treated, surviving insects generally do not return.

Will Final Hex harm plants and damage other surfaces?

Yes. Final Hex can harm plants and may damage siding or other sensitive surfaces. Avoid spraying vegetation, finished surfaces, or materials not intended to be treated. Test an inconspicuous area before full application.

Do I need protective gear when applying Final Hex?

Protective gear is recommended during application. Wear gloves, protective eyewear, and long sleeves to minimize exposure. While the ingredients in this formula are generally recognized as safe, it’s designed to kill some tough pests!
