Ortho Home Defense Hornet and Wasp Killer7, Kills and Prevents Wasps, Yellow Jackets, Mud Daubers, and More, 16 oz.

A bit of advice. Research the type of nest or hive. Once you find out what type of nest to hive it is, you can determine the type of spray foam or spray killer you think would be most affective. During the spring and weather warming up, I noticed a mud dauber nest forming on the front door on the ceiling overnight. Small, but mighty! Once that foam hit? A wasp immediately flew away! I honestly haven’t smelled anything. Not like hot shots where sense can make me sick. However, it has kept the wasps away. And I’m satisfied by that! I do it everyday to 3 times just to keep them from coming back. Hopefully I can get a brave soul to help knock it down and go bye bye! Ain’t no stinging bug coming by me! I’m pretty satisfied. It does take time and research (thank google) and knowledge in the bug department, to determine which type of hive it is. Then you can tell if this foam spray works quickly and effectively. Sometimes it takes a couple of brands to determine the killing ingredient for each brutal hive or nest. But so far? I do love this one! It’s powerful. Granted it has sprinkled foam but it does spray far! And that’s all that matters! It kept them stingers away!

This has easily been the most effective pesticide I've found for dealing with wasps thus far, even managed to get rid of the wasps that were flying in & out under the overhang of my house behind the siding (expecting there is probably a hive under the siding, but I never saw another one fly out or in from there again after I sprayed that particular crevice on the front of my house from one end to the other). I suspect it leaves a residue behind that is deterring them from coming back to the same locations that you may have sprayed. I usually only see small hives (pretty rare to find one larger than a super ball, but it has happened), but spraying the area around it in addition to the hive itself is usually enough to keep them from going back to that particular place.Of course these wasps are pretty persistent & keep coming back (they've been returning to the same place under the siding for years, that was until I sprayed it with this poison), I keep finding new hives I have to take care of fairly regularly in different places, but this poison gets rid of any new clusters fairly quickly (until they come back & start a new one somewhere else). Because of this & running through cans fairly quickly, I've been purchasing these fairly regularly (usually 3 cans per order, but those typically only last a couple days to a week), but based on their effectiveness, I see the cost fairly cheap based on it's performance.Note that I've also tried a Raid brand that can spray 30 feet away (spray, not foam), but the effectiveness of that product didn't even come close to what the foam brands can do, I typically won't purchase anything other than a foam pesticide when dealing with wasps anymore. Of course I am still looking for another option for those that keep returning after I take care of another one of their hives, so I might consider purchasing some kind of deterrent (maybe some kind of fogger) if I can find something that will work.I will point out however that it's possible to get a can with a bad top on it, I did once out of the 9 cans I've purchased over the past few months (1 still unused, 1 I've started to use, the 1 can I had to throw away & get a refund on it). The top on it apparently was not correctly fitted to the tube & the poison came out on my hand 4 times before I eventually gave up on it & called Amazon to explain the issue. I didn't see the loss of the can as a big issue however, just knew it would be sooner before I ordered more.

The product works well when everything is operating as it should. I purchased a single bottle to try it out and it worked so well, I purchased 4 more. The second shipment had 1 defective bottle out of 4 where the spray mechanism was broken and would just ooze foam out of the top. The rest worked as it should. The product itself works as advertised. Coats the nests with a thick foam and seems to kill or disable the wasps on contact. Follow the instructions and spray in the early morning just before dawn or late at night when wasps are back at the nest and inactive. The spray is a narrow stream and can reach up to about 20 feet. It hit the tallest tip of my roof. Be aware that this product runs out fast if you like to coat a medium sized nest with a lot of foam. I needed a total of 5 bottles to treat around 10 medium sized and a handful of small sized nests all around the house and garage. WARNING, DO NOT stand directly under where you're spraying! Not only will you risk catching some of the mist back on yourself, the foam will drip down once you build up a good lather on the nest because, well, gravity!If you get a defective bottle (probably damaged in shipping as they don't wrap these in padding), Amazon live chat will take care of you. The automated refund/return system marks this as non-returnable so you'll have to go through an actual customer service rep.

I used the product on a Paper Wasp Yellow Jacket nest under the eave of an out building, and was surprised by the steam of foam that came out of the can. I suppose that I would have been prepared for the stream of foam if I had read the can closely but, I am legally blind and just didn't see it listed on the can.The foam knocked down the active adult wasps on the nest and killed them. It also soaked the nest quite well and hopefully killed the wasps that had not emerged from their larva or pupa stage, but I have not checked that out.The product seems to work well and the foam stream that it produces seems to shoot out to around 15 to 20 feet. My only issue with the product is that it seems to not produce very much of the foamy product. By that, I mean to say that it does not produce as much killing stream as other products that I have used in the past,and that is why I gave a 4 star rating in the "Value for Money" section of this review.I have repurchased the product just to have on hand when other nests are spotted. I will update this review when I have depleted those not yet used cans.

We get a lot of wasps nests in the summer, and they are usually in hard to reach places. This gets them quick and easy. I can just spray and run for my life! haha.
