Wasps and hornets strike fear in many, but with TERRO® Wasp & Hornet Killer, you can kill these dreaded pests on contact.
TERRO® Wasp & Hornet Killer is an entrapping foam spray that coats nests for a complete 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 of returning.
Going the Distance
Nests are often located in hard-to-reach places, so you’ll appreciate that this wasp and hornet aerosol spray delivers a powerful jet spray that reaches up to 20 feet away. This also allows you to keep a safe distance away from the nest while spraying.
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. 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.

I completely covered the nest with foam and after it dried it couldn't believe it worked so good.

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.Date published: 2016-01-27Rated 4 out of 5 by xxxx from Revision to prior statement When 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......Date published: 2015-06-21Rated 4 out of 5 by pseudonym from Amazon Review We used this to completely soak a large paper wasp nest outside our house in the late evening, and by the next morning there were no wasps to be seen, except for a few dead ones on the ground beneath the nest. Can sprayed a long distance as label indicates. Despite the advertised claim of safety as long as it is kept away from areas where food is eaten or prepared, I'm not sure that I would want to use *any* wasp spray indoors.Date published: 2014-08-22Rated 4 out of 5 by Bee from Amazon Review The spray does not project as far as promised, or even as far as some of the competing brands. But it did help kill yellow jackets.Date published: 2014-08-15Rated 4 out of 5 by B. Colonna from Amazon Review I have used a few types of wasp killers in the past. Most project a stream of spray anywhere from 10 to 20 feet away from the nest. I usually use Raid or Spectracide. I don’t think any of the sprays reach their claimed distance. Spectracide claims 22 feet. The best I ever achieved was about 15 feet. I am sure it varies in their controlled tests and from can to can, climate, etc. For my use, which is typically near my deck or house or in my yard, 15 feet is plenty. This brand, Terro, claims to be able to be applied from 20 feet away. I have used it at about 6-8 feet, and as much as 15 feet. Beyond that I don’t think it reaches, and loses accuracy (hits a wider area than the intended target). It appears to be just as effective as the other brands. I do think this is a better “day time” spray. Most sprays tell you to use it in early evening, after wasps have returned to the nest. Sometimes there are a lot of wasps about and you want to use your deck or areas right outside your home though, so you may find the need to use a spray in the daytime. This spray forms a foam over its target, so it traps wasps, while also killing those who try to escape. As far as effectiveness on contact, I have found that Raid will usually result in an immediate kill, with many wasps falling out of the air as the spray touches them. With Terro, it seems a few who made it through the foam died soon after, but maybe hung on for a few seconds, more so than with Raid or Spectracide. While the encapsulating foam is a great way to instantly “lock down” the nest and destroy its inhabitants, like any other spray, it does leave you with some clean up afterward. Nothing that you can’t hose away afterward. Depending on how heavy you apply it (it doesn’t take much to kill the wasps), you have a white foamy clump for 5 to 15 minutes. Terro says this product may be used indoors. I would avoid using any spray of this type indoors. I have used it on my deck (pressure-treated wood) and against my house, near mortar and my vinyl siding (a tan “Cedar Impressions” shake style vinyl). It doesn’t appear to stain. It leaves some residue until it is hosed away. I would recommend this product. I don’t know that it performs any better or worse than others, but again, if you plan to use it during the day when there is a lot of activity around the nest, you may prefer this over other brands.Date published: 2014-07-29Rated 4 out of 5 by realnaynay from Amazon Review It did get rid of my wasp problem, so I was happy about that, but the range of the spray was much shorter than conventional wasp and hornet spray, so you do have to get closer to the nest to spray. The foam does seem to help if you get a direct hit on the wasps themselves, but if you are spraying the outside of the nest, do not expect the foam to stay up there, it will fall right back down.Date published: 2014-07-23Rated 4 out of 5 by Ravens Den Books from Amazon Review The foaming action does an excellent job of covering the nest and catching any wasps heading back to the area. The spray distance is only about 12’ and a bit more difficult to direct your aim than the liquid sprays. Used on painted wood and metal with no ill effects. Killed all wasps that came in contact.Date published: 2014-07-15
