How to Safely Get Rid of Wasps and Hornets

Understanding and Identifying Wasps

"Wasp" covers thousands of stinging insects: yellow jackets, hornets, paper wasps. Unlike bees (essential pollinators), most wasps aren't pollinators. They can be aggressive, stinging with swelling and allergic reactions. But they're also predators of other insects—don't destroy without cause.

Identify by body shape: wasps have a distinctly thin waist; bees are uniformly thick. Wasps look sleek, lacking bees' fuzzy pollen-gathering hairs. Color isn't reliable—many wasps are yellow-and-black, some hornets black-and-white.

Best Way to Get Rid of Wasps Naturally

Yellow jackets nest underground or in hanging paper nests. Paper wasps build umbrella-shaped combs under eaves and limbs. Leave nests alone if avoidable—wasps use a nest only one year, though they may return to good sites.

If you find a nest in early spring (small colony), seal all openings. Never block a nest inside a house wall—wasps will chew their way indoors.

Knock down nests in spring/early summer with a pressurized water spray from 15–20 feet away. Be ready to run.

Wasp baits and traps work only early season. Remove by midsummer to avoid attracting more.

Eliminate attractants: decaying food, open garbage/recycling, pet food.

In spring, caulk and seal exterior cracks to prevent entry.

Using Chemicals to Kill Wasps

For large nests near people, especially late summer, hire a professional. If allergic, never attempt yourself.

If DIY, wear full protection: long pants/coveralls, long sleeves, boots, gloves, hat with insect veil. Seal cuffs to boots and sleeves to gloves with tape or rubber bands.

• Ground nests: Use insecticidal dust—sticks to wasps entering/exiting.
• Above-ground nests: Use jet aerosol wasp spray (10–20 ft range). Never climb a ladder—wasps can attack before you descend. Plan an escape route.

Treat at night or early morning when wasps are inactive inside. Follow all label directions. Stay away from treated site for a full day; repeat if needed. Never use these chemicals indoors—call a pro.
