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

Outstanding performance! I used this in my attic to treat a wasp nest. You do need to keep shaking the can during use, but the 3-metre range and strong, direct spray were very effective. For the best results, keep the can upright while spraying. There was virtually no smell, which was a bonus when using it in an enclosed attic space. The foam expands like shaving cream, so it quickly covered the nest, and the powerful stream of liquid broke through it with ease. To be fair, the nest wasn't huge , about the size of a football. The nest entrance was tucked away in the corner of the attic, so I bought two cans just in case the wasps became aggressive. In the end, the application was straightforward and I only needed one can. The only thing to be aware of is that any loose or flying wasps can be difficult to hit, as this is a focused, direct spray rather than a wide mist. And you have to keep the can upright and shake regular to get the jet spray The effect is quick and within 10 for them to die and then about 1 hour later no activity on the outside of the house at all. will check in 24 hours Overall, I'd definitely recommend it. I'll upload a few photos to show the results.

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.

UPDATE: I was checking daily for about a week, and the nest appeared to be empty after using the spray and a powder (see notes below). However I went to mow the lawn today, and ran over the hole where the ground nest was located, and found that it was fully occupied once again. I was stung for my troubles. My fault, as the product instructions do indicate that more than one treatment may be necessary, but I was lured into a false sense of safety because there had been no sign of activity for many days. Just a warning to others not to take it for granted that an apparently abandoned nest actually has been abandoned. ---------------------- This product was designed for a conventional exterior wasp nest, not an underground one. I had no idea that some wasps tunnel underground and enter the subterranean nest via a hole at ground level, but this is the situation I had at the end of my garden, against a stone kerb. I wasn't much bothered by it, because the wasps ignored me whilst weeding and even mowing, but I was told that they become a nuisance in late summer when wasps feed on fruit, become "drunk" and very aggressive, and queens begin to leave the nest to find new homes (setting up nests nearby in the following season, thereby raising the number of wasps in the immediate area). I have an early apple tree next to the house, and for the first time the wasps entered the house in ridiculous numbers. In the garden, they were indeed very aggressive, meaning that the apple tree was almost unapproachable. I didn't want to find myself with a bigger problem next year, so decided to eliminate the nest. I was aware when I bought it that this was not designed for underground nests, but decided to give it a whirl. This is a foam, with a lever that promises that if you give a canister a good shake you should get up to 4m range. It was no better than 2m maximum. I used the one canister five times to fill and cover the hole, over two days. The foam vanishes within a couple of hours but each time it reduced the number of wasps. When the canister was empty, there were still a small number of wasps entering and leaving, so I resorted to a powder by the same company. This eventually sorted the problem, and I filled the hole with sand. At the time of writing, four days after both treatments, the wasps appear to have given up on the nest - but see UPDATE at the top of this review.

Very easy to hold so if disabled or arthritic hands this is for you. Easy to direct, foams up immediately. I did 7 applications and got rid of the wasps nest so very impressed with the product. IT does say to do 7+ applications to get rid of the nest and that is what it took. The nest was under the guttering in the plastic soffit with a small hole. Instructions to tell you to do this late at night when the nest is inactive, so 11pm was a great time every night and got rid of the blighters! Worth it's weight in gold and will save you a pest controller out. Put down sheeting so in case of drips from the foam melting as I have dogs so took the sheeting away in the morning before the dogs got up. Highly recommended

This product is pretty much as advertised, it shoots a foam jet a long distance, and it acts kind of like expanding foam. Definitely kills wasps, as after we sprayed a ground nest, we could see them trying to burrow through it to get to the entrance, and it didn't end well for them. Main problem with the concept is that unless you can actually get this stuff inside the nest, the expanding foam concept doesn't really do much apart from make a mess on the surface. Unfortunately we weren't able to safely get close enough to get an accurate spray into the nest entrance, so while it did kill a bunch of wasps, it didn't solve the actual problem by killing all the wasps inside. It may have been possible with a 1m long nozzle or something, but probably that would have just angered the wasps into swarming anyway. We ended up having to get in professionals to deal with the nest (who could obviously get closer and use better/stronger/more suitable products) as it was too much of a hazard for us. Most of them in the UK seem to offer same day callout and after about 20 minutes on-site, they were done and there were no more wasps, so unless you're very confident you can safely use this product effectively you probably just want to get a professional to attend.

Excellent product. Really impressed with it. I have a 6.5ft tall hedge and was stung on the arm by a wasp while trimming it a couple of weeks ago. When I went back to the hedge a little later, I noticed quite a few wasps flying in and out of it in one particular spot and could see a fairly large wasp nest and the entry hole built about a foot inside the hedge. I ordered this product from Amazon because not only was it one of the cheapest for the size of the contents but it produces a strong jet of wasp-killing foam that can be sprayed in and on a nest from a reasonably safe distance without having to get really close. After giving it a good shake as per the instructions, I sprayed the jet of foam directly into the entrance of the nest from about 5ft away until the foam covered the whole entrance before I beat a hasty retreat indoors. I went out and checked it half an hour later and by then there were scores of dead wasps on the ground and the bottom of the nest had disintegrated and collapsed after the foam had turned to liquid and soaked it. There were still some wasps who had not been in the nest flying in and around it despite the damage to it so I sprayed the foam again ensuring it covered every inch of the exposed insides and another bunch of wasps fell onto the floor dying or dead. The next day I sprayed the remains of the nest once more and it totally disintegrated. No more nest, no more wasps. It worked really well for me and there is still plenty left in the can for future use if required. Recommended.

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.

I ordered this in addition to the powder product. The powder never turned up (refund provided) so this was used instead. I got 4 'doses' on the wasp nest and it did nothing. The wasps were still there. Also, the product is £4.50 cheaper in my local garden centre - that was a surprise! So I got some of the powder from the garden centre (that never arrived from Amazon!) and did the job with one dose. Waste of money in my experience.
