SpectracideCarpenter Bee and Ground Nesting Yellow Jacket Foaming Aerosol for Insects, 16-Ounce

The long nozzle works great for getting the foam into the holes that have been holes into wood. It is odorless and works effectively against carpenter bees. I was a little skeptical about the price, but it’s a good value for the size of the can. I would recommend to all.

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!

I've fought the battle with carpenter bees periodically over the years. This year 2024, seemed harder than most at least here in the northeast. There is a tendency with these aerosols to take advantage of their maximum shooting with a stream range of 25 or 30 feet - avoid this temptation even though it it's convenient. As the instructions note, you will likely cover broad areas with the disappearing foam BUT you'll be less effective and rather wasteful. Best results per instructions are by applying foam directly into the tunnels the carpenter bees rapidly drill along with the expanding internal hollows. The concept is to have the bee return to the hole and get coated by the foam application. It is then carried deeper inside where it kills the bee and likely its family. If the bee is just beginning its drilling it may pay to monitor its progress over the next days so as to treat an early hole formation. Also, as noted in instructions, when the treated hole has done its work after a few days, cap the hole to avoid future incursions (I've used Mortite or plumbers putty with success). I have NOT used the carpenter bee "traps" that are sold and look like small bird houses that you hang nearby. My infestations seem to favor specific outside wood beams that are about 20 years old).

This product works great on any decks

Got stung mowing by ground bees and had to avoid the area . Needless to say I was annoyed by the situation. I sprayed the area and tried to get most of it down the hole they dug. The bees tried to attack but were drowning in the foam of the spray . So I then placed a huge rock in front of the hole for extra reassurance. Few days later I went to check and saw dead bees outside of the rock I placed. I'm not sure if the product worked since I placed a rock to cover their home but it all in all helped me get rid of them . Would recommend it's the cheapest compared to smoking them out. And if you use my method it will work because the foam from the spray hinders their quick movement so it will give you time to use a secondary method like digging to destroy the nest or smoking them out or blocking the entry way etc.

I bought this because it specifically says foaming on the label. I want something that I can spray into the carpenter bee holes, but this just all comes dribbling back out immediately. It doesn't foam up at all. Maybe it might foam if you spray it down into holes in the ground, but pretty disappointing for use in walls and porch ceilings. It seems like over 90% is wasted.

We bought our house not realizing the damage that carpenter bees can do. I've had moderate success with another brand of spray, but just for killing the bees I can see and hit with the spray. I sprayed the holes and plugged them with caulking, only to see a dozen new holes, bored from the inside out this spring.After reading about some other pump sprays that leak all over and cost a lot, I opted for this product. The small extension straw reaches deep into the bore holes, and the foam fills the nest. 48 hours later (following the instructions) I filled the holes with caulking. There were no bees hovering around the holes, and we've only spotted a couple of bees in the last few days. This morning I noticed a queen, dead on the porch. It looks like we've pretty much wiped out the colony.

Has no effect on flying carpenter bees. Maybe it only works on nests. I didn't have any nests to try it on. They just hover around the porch roof. There used to be a nest there but I plugged it up a few years ago. But every year they hover around it. But, as I mentioned this spray has no effect on fling bees. Oh well.
