Zero InUltra 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

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!

This is probably a good product but unfortunately after following the instructions it still wouldn't spray foam anywhere just dribbled from the nozzle

Good job, took a few time to kill off all the wasps but got there in the end

Killed the wasps efficiently. Difficult to get it in the hole in the ground/nest due to foam. Could be fitted with a longer tube to get into those small difficult places.

My husband said this was difficult to work especially if you are up a ladder. Our nest was under the eves and this was the third can used, yes it did kill a lot but didn’t kill the whole nest.it didn’t spray as powerful as it said. We are wishing we had got some professional in but considering we have paid all this money so far doing it ourselves,we continued with it.

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.

The advert says it can spray a stream of foam up to 4 metres. You'll be lucky if it goes 4-6 feet!! This makes it dead dodgy to apply.It doesn't seem effective either. Despite covering all the entry places where the wasps were going in with several applications, the stripey little beasts are still there. I can see no evidence of it killing even one. If I could give no stars I would.

Have used wasp powder to clear wasps nests for years, but thought I’d give this a try. It was much easier to spray from a distance, and surprisingly accurate, so I coated the entrance to the nest liberally for a good few seconds. The following day, there were still plenty of wasps active, so I repeated the treatment on a few consecutive evenings, until I’d emptied the can. the wasps are still there, so I’m going to go back to trusty wasp powder and risk approaching the entrance. I hope I haven’t annoyed them too much.Others have given good reviews, so I’m assuming that the nest itself is further inside the hole they’re entering through, but I’ve used powder lots of times and never failed to deal with a nest. If the powder doesn’t work, I’ll edit my review, so it’s fair.Thought it was worth adding that wasp powder worked with a single application - as it always does. I won’t buy this product again. Pity, the concept’s good but was waste of money for me.
