Top 5 Best Wasp and Hornet Sprays (**2021 Review**)

These insecticides aren't used specifically to eradicate wasps, but rather a variety of different ground and winged insects. Normally, these sprays are sold in a concentrated form that you mix yourself with water, then pour into a separate sprayer (we recommend something like this) and launch from a safe distance toward the pests in question (in this case, wasps and hornets).

The USEnvironmental Protection Agencyplaces stringent restrictions on insecticides and pesticides, and no product is ever placed on the market that can ever be harmful to humans if used correctly.

That being said, if a product is misused or if accidents occur,exposure to the pyrethrinsis a possibility. If this happens, please seek medical attention immediately.

Aerosol Cans with Spray Nozzles

Many retail-grade wasp and hornet killing sprays are available as aerosol cans, which typically use tetramethrin as an active ingredient.

Tetramethrin is another derivative of the pyrethrin family, so it falls into the same category as the commercial-grade pesticides used to exterminate different types of pests.

Oftentimes, however, the spray nozzles are what pack the real punch, not the actual insecticides. While the chemicals certainly kill the pests, the spray nozzles on the aerosol cans are designed to shoot the chemicals with enough force to kill on contact.

Another important aspect about the aerosol cans of wasp and hornet spray is that the insecticide can be shot from several feet away. The nozzle propels the jet stream forward with enough force so that you don't have to endanger yourself and walk within a few feet of a nest full of angry wasps.

Which Is Better?

Both commercial-grade wasp spray and aerosol cans with spray nozzles get the job done, and they each have their merits.

A commercial-strength spray will always be more effective in terms of efficacy, but tend these sprays tend to be more expensive.

The pre-mixed aerosol cans with an attached nozzle are the inverse: they're more readily available in the retail market and usually cost a little less, but with decreased potency.

Is Wasp Spray Dangerous to Humans?

Okay, so you've decided you definitely want to spray your wasps and hornets away.

But how much exposure is too much exposure? What if a spray nozzle bursts? Do you need a mask to breathe?

Will It Singe My Skin?

Okay, first question: unless you're taking a bath in the chemical solution, chances are that it probably won't burn your skin.

This is an area where it's best to use your common sense:

• DO read all safety instructions on your particular product before use
• DO wear thick rubber safety gloves
• DON'T rub the chemical on your skin
• DON'T touch the pure, unmixed chemical

What If I Inhale It?

Say that you've just inhaled a big gulp of a pesticide. Your next move: get to fresh air as soon as possible. If you are wearing tight clothes, loosen your garments and make sure that nothing is constricting your breathing or hindering airflow.

After that, if breathing problems persist, please contactPoison Controlin your area and/or seek medical attention immediately.

Will It Burn My Eyes?

When you use a pesticide as directed, the fumes and the backsplash should steer clear of your face. If you're still concerned, though, and want to protect your eyes, there's no harm whatsoever in wearing safety goggles while you spray your yard.

However, if you accidentally rub your eyes with your glove or your exposed hands, wash your eyes under the sink immediately.

Be sure to create a gentle flow of wateracross your eyerather than placing your eye directly beneath the stream of water, as this could cause damage.

If retail-grade wasp and hornet spray from an aerosol can comes into contact with your eyes, it will result in extreme pain. However, it's unlikely that permanent blindness will occur.

Some wasp and hornet sprays have the nozzle attached right on the container. With these types of sprays, you simply shake the canister and you're good to go.

Some others require a separate sprayer nozzle to spray the solution around your yard. We've listed the products in our detailed breakdown which require the extra equipment, and we recommend buying a universal spray nozzle likethis one.

Alternately, if you have tall trees, it may be a good idea to invest in a 30 foot wasp pole--a special extender pole designed to spray insecticide from 30 feet away.

We recommendthis optionfor a sturdy, reliable extender pole in order to get to the hard-to-reach spots in trees or out of your normal reach.
