Spectracide Carpenter Bee and Ground Nesting Yellow Jacket Foaming Aerosol, 16-Ounce

This is the ONLY thing that FINALLY killed our Yellowjacket problem! My 12 y/o son and I are both very allergic to ALL bees! And we had thousands of Yellowjackets make a nest in between the wood boards and into the ground behind it, right in our parking area next to our front porch! The bees apparently did this while we were on vacation. I got stung 5 times just trying to get into my car twice!!! I had to try to park back farther after that, and walk in a big circle way around that area just to have to try to get near it anyway to get onto our porch to get in the house. We tried 4 different sprays that said they killed Yellowjackets. NONE of those even affected them!! Every single night, my fiancé sprayed the area in between the the wood where the bees came in and out. That way all the bees were in the nest and would get the poison on them. This spray is GREAT because it also expanded into the wood into the nest itself that was in the ground behind the wood that we couldn’t get to! Every single morning, we seen about 50-80 bees dead on the ground in front of the wood! We had to spray nearly an entire can every night for a week and a half to kill all the bees that were in that HUGE nest!! After there was no more bee activity there, my fiancé sprayed the area with clear flex seal to help reseal over it so that the bees couldn’t get back in there. There are now no more bees there and my son and I can now safely get in and out of my car and I can park back in my parking spot!! NEVER STOP MAKING THIS SPRAY!!!! It saved both mine and my son’s lives…. Along with our Epi-pens! We couldn’t be more pleased with how quickly and effectively this killed the yellow jackets when nothing else would!

The nest was underground then up under my sidewalk. Nothing else would touch these wasps. They laughed at my wasp poison spray. They flew right thru clouds of it. They bit my dogs and friends. Then I found this Foam. We would see new holes pop up from different sides of the concrete. But we foamed each one. We got them. The foam worked. It built up into areas the spray wouldn't reach. Quality good. Spray and straw worked well. Effective.

It works - I could witness how ground nesting yellowjackets get incapacitated and die when this pesticide is sprayed on them. The efficacy can vary depending on how long and wide the underground tunnel from the surface to the next is. If the tunnel is not straight and shot, even foaming action may not be sufficient to reach the nest. I tried injecting it into the hole in the ground, and after excavation I can see a dozen or two yellowjackets killed by it, but foam did not propagate all the way (it seemed that nothing has changed by the next day) and I still had to dig into the ground to get access to the nest. I am very glad that I got a bee suit ahead of time, as there was a point when a cloud of yellowjackets emerged from the ground when their nest was hit with a shovel. They would kill me without a suit, but in suit they seem to not even notice me. A few of them ended up sitting on the suit but could not sting me. My judgment based on limited experience is that typically, it can be more of an aid to the process of digging rather than a simple to use, single step solution (which probably does not exist). The recommended on the can way of using it is via a straw inserted into the nozzle. This creates an option of injecting foam into the hole. The stream is not strong enough to hit nests in the trees or above your head or from a significant distance, and in any case, spraying the entrance would not eradicate the whole nest. If the nest is large, you probably will be better off sucking them out of the nest with wet vacuum with soapy water to drown them. It is really difficult to completely destroy the next by injecting foam into it because you would need to dig into the access tunnel gradually and get close to the nest to make sure the spray reaches it. Since yellowjackets will not like it, you probably need a bee suit no matter what if you try to get so close to the nest to insert the straw into the hole. If you have a bee suit, well, then you have a very wide scope of options, including just destroying the nest and letting them fly away to find another home. Before you hit the nest with showel or garden hoe, the foam might not reach the nest (or maybe it will if you are lucky, but there is no guarantee), and after you hit the nest, all those yellowjackets are all airborne flying around you and there is nothing to spray on, except the remains of the nest, if anything or anyone is still there.I got one can from amazon and a day later got another one from a local hardware store. In retrospective, it was not even decisive in the outcome, just help, but not a solution. A garden hoe and a bee suit were much more effective. Your case may be different.

This bee and wasp killer is basically my personal superhero cape. Every time those buzzing nightmares show up, I just spray, and boom—instant peace. I’ve survived countless battles in the war against stingers, and my terrified wife can still see tomorrow thanks to this trusty can. If I had a medal for “Most Valuable Wasp Slayer,” this product would have it. Five stars, because thanks to this, I’m still here, and our outdoor snacks remain unmolested.

I squirted the whole bottle down and aound the yellowjacket hole in my yard and I don’t think it bothered them in the slightest. It’s 3 days later and they are still there.I think they like it. Maybe they sent me a bottle of yellowjacket vitamins instead of yellowjacket poison. I don’t know

Please be aware the first time I ordered this it worked great and does kill on contact. Needing more I placed another order that does not foam or even spray as a liquid. Amazon was very helpful and issued a refund. That same day I placed another order because I am battling an underground nest of yellowjackets and I really need this item. It arrived today....it too does not work. Amazon has issued me another refund although I still need more yellowjacket killer. Not sure what brand to try next. I also contacted Spectracide about this problem and was told they are not aware of any problems although possibly if it is not being stored properly in extreme heat or cold that can affect it causing it to not work properly.

Kind of works, but if I did not have a bee suit, I could never get close enough to use it. Just a shovel of dirt over the hole is probably just as good as yellowjackets can't actually dig.
