Zero In Wasp Nest Killer - Insecticidal Wasp Nest Destroyer Foam Spray for Indoor & Outdoor Nest Removal - Fast-Acting Foam, Effective Wasp Spray Up to 2 Metres, 2-3 Treatments Per Can - 300ml Aerosol

Very effective. Took care of my small/medium sized wasp nest in just one spray.

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.

Did a fine job but needs to fired at a nest not just an entrance say.

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.

Had wasps coming and going gap in a wall building a nest, waited until late evening blasted this stuff in the hole and entrances , next day still noticed a few coming and going, repeat same step again in evening and, not seen a wasp since so very happy does the job

Very disappointed. Applying foam stops wasps accessing their nest, but in warm weather the foam disappears after about 10 mins and the wasps came back. Used the foam about 10 times in a day before looking for an alternative product.

100% Recommend, treated my nest above the front door at 9:30 pm when it had cooled down, in the morning there was a pile of dead wasps, treated again to be safe, got rid of the nest in the evening. Cant go wrong for the price

We were going to ignore the wasps under the ground floor via an air brick. Too many and getting close to the grandchildren. Purchased one spray can of zero in, waited till it was dark and kitted up with a full face snorkel and rubber gloves. It took 3 full blasts at about 10 secs a blast through the air brick and then all over the air brick . In the morning there were hundreds of wasps dead on the floor. A few stragglers but they disappeared too, excellent product.UPDATEThere back! Not as many but still in the 40-50 mark. Now on my second can of the stuff however it does seem to be ineffective now. Tried getting the nest from inside by drilling a hole in the floor boards alas they are still coming through the airvent. "2nd can made no difference.Now trying a powder instead (Pest Expert formula P wasp Killer) fingers crossed.Update.Within 2 hours of using the powder every wasp is a goner.Placed powder all over the air vent and watched the wasps moving the powder.( Formula P 👍)
