Wasp Nest Killer Foam

Bought on Prime weekend x3 cans and had no use in '25. But worked well in '23/'24 one can will do a nest in a house if you spray the entrance over several nights as Wasps heading home. Now have x3 cans in stock bring it on Wasps '26.

Had a wasps nest behind some brick at the kitchen window. So bought this to try. The foam is good and shoots out a good distance. More importantly it took me four occasions which were a day or two apart. It initially didn’t work on the first go but that’s not unexpected. After four sessions. I haven’t seen any wasps in about a week. I’m confident that this product done what it should do so Will recommend it. Not overly confident the best won’t return at some point, but at least I’m prepared to use this again. 100% rating that this will work

Over the summer I found that we had three nests in our property. One entrance was quite accessible so I sealed the hole up. After a couple of days they made another entrance! So desperate needs etc. In total I ordered two cans of spray and I have to report that it does work. I sprayed the new hole. I found the spray works best if you can hit the nest directly, but in this instance this was not possible. The other two nests were massive, about 2ft6 wide and 2ft down. These were in the main house loft. So suitably covered, gloved and masked I sprayed the first nest which upset them no end. So a hasty retreat. Next day the nest had all but collapsed. I then sprayed the second with similar results. The first nest I mentioned was proving to be more of a problem. After repeated spraying I had success. The spray does reach probably 6ft at quite some force so is good for penetrating the nest structure. Just spraying through the hole has limited success, but patience and a second tin will win the day.

My use: To get rid of wasps that had set up home in a roof of an outbuilding (pot pan tiles). After just having some roof work done I didn't fancy getting pest control out to re-disturb the roof tiles after they'd just been placed back correctly. I've tried all sorts to get rid of the wasps including scented spray, pop-up fake wasps nests, high-vis wasp traps and this foam spray. Ease of use: Just shake the can thoroughly and spray the nozzle at the source of wasps. In my case this was at holes under the pan tiles where the wasps were regularly flying in and out of. The nozzle and pressure allows between you to shoot the foam between 1 and 2 meters and is really easy to use. It is sometimes effected by the wind when spraying and also when the foam has landed. Upon hitting a surface the spray foams up in a similar way to expanding foam. Effectiveness: This spray does kill wasps but unless you have a whole load of them to aim at, it's a little limited. This is because the foam doesn't froth up for long enough before it disappears. If aiming at a gap, the wasps can just avoid the foam. Also unless they get a lot on them it doesn't kill them straight away. You really want them to take the poison back to the nest where it kills the young or the queen. I also applied this to cotton wool balls and poked them under the tiles so if the rain did wash the poison off, some would remain. I used x3 cans of this in a short period of time and it's expensive at £8-12 per can. I didn't find that this cured my problem. I found high-vis wasp traps to be far more effective at killing them. See my review.

Did the job

I don't normally write reviews due to lack of time however I felt this needed to be said. In my case, wasps entering and exiting through a brick work hold on an approx 1 foot thick wall this did not work. Appreciate it is a nest destroyer, however indications on the can and other reviews seem to advise application to entry and exit points will do the trick. I bought 2 cans, and applied 7 times over a period of a week and a half. What it seems to do is deter the wasps for a day or so, and then they become active again. I double and triple checked both sides of the wall, and sat for hours on end calmly mapping out the entry points and all the areas the wasps physically walk on. Having tried directly filling the entry hole until foam started seeping out of other areas, to coating a 3 square foot area around the entry hole to ensure contact still no result. Finally, just to test it out and dressed up in heavily protected clothing when the wasps were active around the area, literally coated the wasps in foam (the last amount left in the 2nd can) and watched as they glooped around in it. They didn't die from direct contact, they were incapacitated for a while until they dried out a bit and then continued to fly around. I may have had a dud batch, as other people reported results, my advise would be while they are calm try and catch one in a jar and then test out this foam first. I took into consider weather conditions, alternate access point etc. However when I saw myself direct contact didn't make a difference i realised what the foam is doing is blocking up the entry/exit points. The wasp then panic and can enter or exit, disappear for a few days and then resume activity. My guess is direct contact with a nest does destroy the nest which then the wasps must actually leave rather than rebuild. This however is a guess only. I have ordered powder now for roughly the same price from a different manufacturer and will be able to make a direct comparison. Thanks

Brilliant stuff, one can killed off the whole nest which had gotten inside the eves on my house. I couldn't even see the nest so it was an educated guess point, spray & hope for the best job. Within minutes a lot of very angry wasps has fleed within an hour it had gone quiet. The next morning there was just one wasp trying to get back into the area I sprayed the little bit I had left and bish bash bosh the job was done. It's a week later now and no wasps. My mother in law had a professional remove her next last week and it cost her £90, so it was the best £6 odd, I've ever best. I highly recommend 👌

I bought this to get rid of a wasps nest that had set up shop in the soffits & fascia on my house last month. The local council and pest control agencies wanted £45 plus VAT just to come and assess the problem without eradication so for £3.99 I deemed it worth a try to DIY! My first concern was how to access the area without risking a ladder, but I found that the spray can squirt at least 8foot and is easily directable so I shot at the nest from my first floor landing window and scored a direct hit every time. The little blighters got quite annoyed but soon started dropping like the proverbial flies and within 24hrs the majority were dead or dying. I gave the area a couple more squirts over the next day just to ensure the job was done and even now a week later the little blighters are still dropping out of the soffits and expiring. I found this spray much more effective than the equivalent rentokil one I'd used earlier in the year for a ground based nest which I eventually managed to get rid of using the powder. Having experience of two nests this year, I'd say this is the best spray product to use and saved me at least fifty quid.
