Ultra Power Wasp & Hornet Nest Killer Foam - Insecticidal Wasp Nest Destroyer Foam Spray for Indoor & Outdoor Nest Removal - Effective Up to 4 Metres, Kills 4-7 Nests - 600ml Trigger Aerosol

Had a wasps nest where two parts of the roof meet, about 1.5 metres from a window I could lean out of. In my haste to start the massacre, I didn't shake it (and didn't wait until evening either). The liquid came out in a jet and the foam coated the roof around entrance to the nest - wasps went mad and started dying almost immediately. After a couple of applications, I realised I hadn't shaken it as per the instructions, so I did so and tried another application, but this time instead of a jet, it foamed up on leaving the can and would only travel about 1m. Shaking (at least when the can was partially full) seems to have stopped the jet from forming, so might account for a few of the reviews I read saying they had a dud product. Regardless, it's worked very well, the wasps are dead, and I didn't need to get too close.

Totally useless. Nothing like the advertising. The foam stream is very weak and only travels about 12" or so, if you're lucky. It doesn't work, hasn't killed a single wasp, and looks more like the wasps are using it a shaving foam! It also looks like there should be a small pipe to attach to the nozzle to squirt it into the entrance hole of the nest, as there is a small clip on the side of the can. Some people have fedback that it does travel a long distance, whilst others, like myself, report it has a very short range. I can only summise that some have a lack of propellant/gas in the can.

Apt an effective remedy for wasp infestation that is value for money.

So I have had to kill two wasp nests in the garden. One last year, one this year. The first was in tge ground in our greenhouse. A bit easier to kill than this year’s. I didn’t shake the can at all, and a powerful jet hit the entrance. Any wasps that did fly got hit by the wasp spray from the same firm in my left hand. Dead after one application. Jet foamed on impact - very effective. This year the nest was built into a plant, and harder to hit the entrance. I cut the plant back prior to spraying. Sadly, I DID shake the can, and this means it foams instead of jets out of the can with less range and accuracy. If you have shaken the can, wait until later before spraying. One key suggestion - but two cans of killer foam. It suggests on the can you spray for up to 12 seconds to kill a nest. If you have two cans spraying at one, you only have to spray for 6 seconds (just saying). Make SURE you hit the entrance to the nest. If the nest isn’t completely dead, spray during the day next time when the wasps are active. You want them to get foamed! This year’s nest was resilient, but determination eventually killed it. The foam does work. Buy two at once, or four if you want to be ready for next year too! If you don’t shake the can, you can stand far enough away and still be accurate.

Having had a roof tiler refuse to continue his work after discovering wasps (nest) in 'eaves', I resorted to this because of its claims about 'throw' (4 metres!?) I'd read the poor reviews dismissing this claim but for £8 thought I'd try it. First issue was the instructions which apart from stating to shake container, there was no indication as to how much. I decided to shake for (several) minutes but there was no 'feel' like something inside moving. For contrast I've used spray paint and in them you can hear (& 'feel movement') of a ball bearing but not with this aerosol. I was using the can 'up a ladder' (not recommended) and required about a 1-2 metre 'throw' but whilst there was an intitial 'burst' most fell well short and landed on roof tiles leaving a residue... see photo. I'm hoping this disappears with rain! A few days later, I tried again with more success because(?) the emptier can was easier to shake ..... I could hear (& felt) a difference from the first 'full' attempts. The 2nd photo shows how more successful this attempt was. I don't yet know the outcome but it was obvious this time that wasps couldn't 'get in'! I should also add that there were a number of dead wasps on the roof tiles where the 'previous residue' had landed so it does seem that this foam does kill wasps effectively. IF the manufacturer could achieve the 'throw' it advertised, this would be a great (5*) product but as it is, I find it difficult to recommend. UPDATE: Disappointingly, the "foam accumulation" (created on my 2nd use of aerosol & shown in photo) disappeared(?) all too quickly and wasps continued to gain access. I feel that there has been a (slight) reduction in wasp numbers but worryingly, they now seem to be exploring other places nearby so I might just have shifted the problem! If the aerosol allows, I'll give it another go. UPDATE 2: Having discovered that this aerosol seemed to work better (longer 'foam throw') with longer shaking of can, and that this was easier to achieve as the canister became emptier .... 2nd, 3rd .... uses. I tried once more, with greater success but it was still difficult to sustain the 'foam throw' distance in order to achieve a satisfactory blockage of the 'wasp ingress hole'. Today I had someone around who removed some of the 'roof wood' allowing access to the eaves. They discovered that whilst wasps were still 'active', that activity had seriously diminished and there was a very large number of dead wasps so some success! Based on my experience, I continue to believe that with better design (& instructions) this could be a very good product and I would buy it again IF the wasp nest was visible rather than as in my case, being 'hidden'. I've increased my rating from 2 to 3*

This stuff really works. I live in a bungalow and I had a wasps nest right outside my lounge window, little buggers kept flying into the lounge so I had to close the window. At that point, I didn't know I had a nest, I just got a little suspicious as to why so many wasps were in my lounge. Anyway, right under the eves there was a little gap leading to my loft and they were coming in and out, but at that stage, they were all pretty small so the nest must be at an early stage. I couldn't reach it without a ladder but I wanted them gone, so I looked through Amazon's huge range and settled on this product along with the powder. It arrived the next day so just before dusk I went out and without the need for a ladder I gave the hole a quick blast. It was very simple to do and seemed to cover the wasp hole nicely. A few came out but were covered in the foam and couldn't fly, I left them to bed down for the night. I had a look the next morning and they were still in and out of the nest, so I got the foam and gave the hole another quick blast of the foam, which covered the wasp hole nicely once again. A fair few wasps came out of the hole again but couldn't fly due to being covered in foam, I left them to settle in for the day. At dusk, I got the ladder and squirted the powder into the wasp hole, and got away from the nest pretty darn quick. Quite a few wasps trying to fly back into the wasp nest were stuck as the hole was blocked with the powder and they were getting covered in the powder, I left them to settle in for the night. The next day there were still wasps flying in and out but not as many as the day before, I got up the ladder and gave the wasp hole another squirt of the powder blocking the hole. Once again quite a few wasps were trying to get back into the wasp hole but it was blocked with the powder, I left them to settle in for the day. The next day they had managed to dig the wasp hole out but there were no wasps coming out. I kept an eye on the nest and still to this day there are no wasps anymore. I don't know if it was the foam or the powder but the nest is dead and gone so as far as I am concerned it's worth the money. I know the nest is probably in my loft and the wasp hole I am poisoning is only the entrance, the wasps do the rest by carrying the poison back to the nest, infecting more wasps and eventually killing the queen.

Felt guilty doing it, but it had to be done. Works very well!!

I had a large wasp nest and I purchased this treatment to deal with it. Firstly, this doesn’t spray as advertised. The foam jet pressure was weak and only has around a 30-40cm spray reach. I was constantly ready to run as wasps were coming out of the nest as I sprayed it, but to get the foam on I had no choice but to stand a lot closer than I would have hoped based on the product description. It was generally ineffective against the wasps. A few died that got hit by the foam directly, but the nest itself remained highly active, even after the nest had been resprayed when the first layer of foam had dissolved . Eventually, I purchased a different treatment which did the trick in 20 mins.
