Zero In 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.

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.

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

Last year I had two nests to get rid of but due to their location - both behind brick - I had to use powder to puff in to the gaps. This year's nest was a big one out in the garden, under a bush. Underground under a bush to be exact. It took a bit of sleuthing to find the actual entrance and this was much easier done at night with a torch. Entrance found - and a very large tunnel entrance too! So, the next day, I had a quick spray of this stuff as a test so I was prepared for how it worked in case I needed to act quickly and make a sharp exit. That night I went out to the nest in darkness, with my torch, to have another look. All very quiet with zero activity. Perfect time then. I fired this stuff in from about 2 metres back from the entrance and let it rip for 8s, as directed on the tin. Seemed to leave a nice foamy mess and still no activity. Last year, with the powder, it really stirred up a frenzy! Next day, zero activity!! This worked after one applications. Before it was like a wasp M6 with a constant stream coming and going, but now - zero, zilch. Not one of the blighters. Two days later and still zero activity so I can conclude that the nest was well truly obliterated by this stuff. Excellent. I did think it was a bit pricey at the time but based on the results I take that back. Highly recommended to get the job done first time. Well, it did for me anyway!

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.

Do not buy Complete useless only dribbles out of aerosol.All instructions followed Complete waste of money

Didn’t help with the wasp nest in our compost bin. This was the second bottle, as the first made little difference sprayed into the entrance. This second bottle also didn’t spray properly and at times not at all unless we hit it on the ground, so had to get much closer which result in stings. In the end we pulled the bin over to expose the nest, smashed it with a long pole and sprayed this direct onto the pieces and wasps. Still didn’t get them all so ended up putting wood down to burn the nest and destroy the eggs. In short, pointless if the nest isn’t exposed and the product can doesn’t work consistently.
