Zero InZero 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

Resolved the wasps who were nestling in our waste bin in no time. Worked a treat.

This is a good product and good value for money . Takes a few goes vs some more effective yet more expensive products. With wasps you have to spray late at night, leave and then do it again and prob again to be sure. Product has a good spray range too. Really pleased with the value for money. Mark

Works perfectly!

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.

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

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

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 👍)
