Wasps and hornets strike fear in many, but with TERRO® Wasp & Hornet Killer, you can easily kill these dreaded pests before they have a chance to sting.
TERRO® Wasp & Hornet Killer is an entrapping foam spray that coats nests for a total kill. The entrapping foam not only kills wasps and hornets inside the nest, but it also remains on the nest and kills unsuspecting insects that have the misfortune to return.
Going the Distance
Nests are often located in hard-to-reach places, so you’ll appreciate that this wasp and hornet aerosol spray has a powerful jet spray that reaches up to 20 feet away. This also allows you to keep a safe distance away from the nest, reducing any fear of being stung.
When treating nests, spray at sunrise or dusk when insects are least active. Stand a safe distance from the nest - do not stand directly underneath it. With the wind at your back, take aim and spray the nest opening until soaked. Then spray the rest of the nest. The insects will fall to the ground and die.
After spraying, wait up to 24 hours before removing the nest.
Safe for Indoor and Outdoor Use
Protect yourself from wasps and hornets, indoors and outdoors, with TERRO® Wasp & Hornet Killer. Here are some tips on where to spray:
- Use outdoors under eaves, near window frames, doorways, outdoor play areas and picnic areas.
- Use indoor in attics and anywhere nests are built. Do not spray around exposed foods.
- To prevent insects from entering home, use this wasp and hornet aerosol spray around areas where insects enter, such as gaps around outdoor plumbing and vents, cracks and crevices in foundations, and along sills and ledges.

Review RateWELL DEVELOPED PRODUCTS.
SO FAR THIS PRODUCT IS ONE OF THE BEST I HAVE USED. IT SPRAYS MORE CONSISTENTLY THAN OTHER BRANDS. WILL BE GLAD TO BUY IT AGAIN.
Review RateGreat product
Bought this product to get rid of a ground wasp problem. As soon as I sprayed it in their holes they are dead and not back any longer. This stuff definitely works great!
Review RateAt a safe distanceThis is a great product. The foam spray has enough range, so you can safely spray wasp nests and make a speedy getaway if necessary. As far as I can tell, it also has a 100% mortality rate. Best. Products. Ever.
Review Rateexcellent productI sprayed a hornets nest that was larger than a softball 8 days ago and have seen a
hornet since then. I completely covered the nest with foam and after it dried it couldn't believe it worked so good. I'm 76 years old and if I can make it work anyone can
Review RateWish it sprayed further
I bought two cases and have used several cans so far. It does not spray as far as other brands and it sprays in too wide of a pattern. If there is any wind at all it goes all over instead of reaching the nest. Up closer 8 ft - 10 ft it will foam a nest over pretty good, but you still see the wasps crawling around for several minuets. I'm kind of disappointed in it. I am allergic to to bees, wasp, hornets and I wanted something that sprayed 20 ft or so and would encapsulate the nest killing them instantly. 8-10 ft makes me nervous spraying the nest. There was another brand that worked better that is no longer produced, if terro wants to know about it email me an I will give you the name of the discontinued competing product.Response From Terro®Patty : Consumer Relations Representative

Review RatePoor Spray
May be great product but no way it sprays 20 ft. Perhaps 6-8 ft. is more realstic. Very disappointed as I needed to reach some high places to kill wasp nests.Response From Terro®Lauren : Consumer Relations Representative

Review RateShipping arrived on time.Great service. I know the active ingredient and sought it out.....finally found Terro. Bought two cans of the wasp and hornet..
Terro termite killer is great and I'm guessing this stuff will be too as they chose the correct active kill chemical.
Review RateRevision to prior statementWhen I initially was asked to write a review I said that I ordered a product but it was never received. So today I can say that TERRO sent my order very quickly. This is a fantastic product. Sometimes things happen that are beyond our control.
Thanks TERRO for honoring the sale and quickness of correcting......

There are more than 30,000 identified species of wasps, which fall into one of two categories: solitary or social. The majority of these species are solitary wasps that live and operate alone. There are only about 1,000 of the social wasps species, yet they are the ones people encounter the most. Social wasps such as hornets, yellow jackets, and umbrella or paper wasps, live and work together in colonies.
