    Would have returned if I had used sooner.
    First I received the red can pictured, not the blue as ordered. I thought it must be the same stuff. NO.The stream was short and a spray, not stream.The wasps just started flying around, not dropping to the floor.By the time I used the product, too late to return.

    I ordered this for my brother in Tennessee. He had 2 huge wasps nests outside his house.
    He is disabled. So I had to get something that he could stand way away from to use.
    He told me this stuff worked great! He was surprised! He said killed wasps on contact.

    Every year I seem to get wasps building nests in the siding of my older home. I typically use another brand product, however I was unable to get it in a timely manner. So using CRC products in the past I gave this a shot.

    I found it worked just as well as the other brand, it knocked the wasps down instantly. I have used other brands in the past that had no instant effect on the wasps, which led to a lot of stings. I was so happy with the way this worked, that I purchased a case. Also this product was priced less than the other brand I was using and it works just as well, instant knock down.

    5.0 out of 5 stars It burns! It burns! Or at least, that's what I imagine the tiny wasp children screamed as their family perished en masse
    Reviewed in the United States on July 18, 2015
    Style: 1 PackVerified Purchase
    I was terrified to touch or breath the stuff, as it seems a little like the illicit back-alley fireworks that may be amazing but may also blow your face off. So, I waited for a calm night (lest the wind tragically blow it back into my face, turning the tables on an otherwise one-sided slaughter) to attack the giant wasp nest that had been under construction above my outdoor stairs for a few weeks. With the attached tube, it sprayed a solid 12-15 feet (not very precisely) at an upward angle, dousing the entire nest, and killing every single one of those evil rascals immediately. Like, instantly. A handful were knocked loose by the powerful stream and died before they hit the ground. The rest of the colony froze in place, I imagine in some sort of quick and silent seizure, because they made no attempt to run or fly to escape the burning torrent of agony that overtook them from below. As such, they remain there to this day, now two or three weeks removed from the murderous rampage that befell their entire waspy family. Through sun and rain and dark of night, the desiccated husks of these once proud papermakers, whose ancestors achieved the magic of flight eons before humans dared to dream of taking to the skies, cling to the remnants of their beautiful hexagonal nursery. I don't disturb this insect mausoleum, partly out of respect for their artistry and unknowing sacrifice, partly as a monument of foreboding to any other harmful insects who may consider sharing my home, and partly because I just can't reach it high up under my eaves.

    So there you go. This stuff is extremely effective. Just...you know...probably don't inhale the stuff or get it in your eyes.

    An update: I gave away my first can of death mist to a neighbor who was complaining of wasps and spiders. She promised to bring it back, but she didn't. She never complained about bugs again, though. I like to imagine that she has secretly eradicated all of the flying insects in a 2 mile radius around her house with my CRC wasp spray. In any event, I moved to a new house, where I discovered another big wasp nest in the eaves of the tool shed. So I placed another order for this stuff, naturally. And, once again, I hit around the corner, waited for a gust of wind at my back, and blasted the entire colony out of existence in mere moments. I counted 31 corpses once the fatal vapors cleared. Done and done.

    4.0 out of 5 stars Does the Job Well
    Reviewed in the United States on June 5, 2013
    Style: 1 PackVerified Purchase
    I had previously asked two other reviewers how they killed yellow jackets with this product and neither of them answered me. My guess is they were both fake reviews written by people who worked for CRC. You can not kill wasps that live underground with this product. However you can kill the standard small wasp or hornet nest and wood bees with it. Wait until they are at the nest after sundown to zap them. Wood bees will be sleeping in the hole they drill too. CRC comes with a inch long tube that, if attached, will give you a good spray distance. Normally when I spray a wasp nest with another spray killer the wasps fall to the ground but with CRC they die hanging onto the nest. Even the next day they are still there. I took the nests down with the water hose and the insects were definitely dead. Very odd but it worked. This product also seems to last a bit longer then the ones that spray foam.

    Update: Since I wrote this review on June 5th CRC has changed the picture listed under this product. Some aspects or descriptions of this product may have changed with the different container. The spray-head is no longer visible and therefore may not be the same as the original.

    This is the best knockdown wasp killer anywhere! Repair HVACR units and most are located outside and on the roof. Many small holes and hiding places for wasps to wreak havoc on your day! I have tried many wasp sprays that the wasps swim down the stream to you and take minutes to die. This one knocks them down instantly, many times they never even make it off the nest. Even if the spray is slightly off target it will get them! I put this in all my trucks now!
