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

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

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.

Absolutely amazing stuff and very easy to use

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.

Great deal at a great price and very fast delivery thank you

I don't normally write reviews due to lack of time however I felt this needed to be said.In my case, wasps entering and exiting through a brick work hold on an approx 1 foot thick wall this did not work.Appreciate it is a nest destroyer, however indications on the can and other reviews seem to advise application to entry and exit points will do the trick.I bought 2 cans, and applied 7 times over a period of a week and a half. What it seems to do is deter the wasps for a day or so, and then they become active again. I double and triple checked both sides of the wall, and sat for hours on end calmly mapping out the entry points and all the areas the wasps physically walk on. Having tried directly filling the entry hole until foam started seeping out of other areas, to coating a 3 square foot area around the entry hole to ensure contact still no result.Finally, just to test it out and dressed up in heavily protected clothing when the wasps were active around the area, literally coated the wasps in foam (the last amount left in the 2nd can) and watched as they glooped around in it. They didn't die from direct contact, they were incapacitated for a while until they dried out a bit and then continued to fly around.I may have had a dud batch, as other people reported results, my advise would be while they are calm try and catch one in a jar and then test out this foam first.I took into consider weather conditions, alternate access point etc. However when I saw myself direct contact didn't make a difference i realised what the foam is doing is blocking up the entry/exit points. The wasp then panic and can enter or exit, disappear for a few days and then resume activity. My guess is direct contact with a nest does destroy the nest which then the wasps must actually leave rather than rebuild. This however is a guess only.I have ordered powder now for roughly the same price from a different manufacturer and will be able to make a direct comparison.Thanks
