Karlsten Hyper Power Wasp Nest Killer & Hornet Killer 600 ML - Gold Standard Long Range 5 Metre Spray for Indoor and Outdoor Wasp Nest Removal - Wasp Killer Spray

This certainly did the job one long squirt and with in half an hour no more wasps .Follow instructions as powerful stuff.

Great product. I had a huge wasp nest in my shed and I used this on it at 9.30pm at night when they were not as active and the following morning the wasps were dead and the hive was empty. It was easy then to remove it and sweep up the dead wasps. Would highly recommend 👍

This sprays as a mist not a jet of fluid, when sprayed outside it does not reach 5 meters.

I had a wasp nest starting under my roof, I livecin a barn and found it when painting. Got stung 12 times. Bought this, sprayed the entrance from about 6 ft away then managed to get closer and emptied the whole can under the eves. Killed all the wasps and no more nest. The reach of the can is really impressive and it lasted longer than I thought.

Just a powerful spray…..no good for wasps nest in ground, apart from the ones outside. Thought it was something like foam that the wasps took in to kill the nest. Bought some powder…..

I had a Hornet nest under my decking, I used this only once, and hornets have gone.

I was slightly optimistic after reading the reviews, it seemed for the vast majority it simply solved the problem, a few negatives I put down to maybe a faulty batch, but recently it seems all OK. So I ordered, a bit pricey I thought but if it gets rid of the wasps? Worth it. It arrived & I waited till dusk, nice quiet night, no wind so I thought this is perfect. The wasp nest is next to a tree stump on the floor, so the 5m might come in handy, I started spraying...wasn't hitting from 5m, I walked closer to roughly 3m & I was sure it was hitting the nest then as few wasps woke up to investigate...to my surprise, they weren't that fussed by the spray, roughly 6 of them flew out and went off somewhere, I carried on spraying the top & entrance (roughly 8 seconds) until the can had no pressure left, a few wasps buzzing but I thought they'll be killed off if they go into the nest, job done! Cut to this morning...I might as well have sprayed the nest with air, no dead wasps, nest still as busy as ever & the entrance like a conveyer belt for wasps. Very, very disappointed, especially when you consider the price. Would it work for a completely exposed nest? Possibly...nothing on the can or description stated otherwise.

Extremely effective! Has a very powerful aerosol spray enabling the wasp nest to be tackled at a reasonable distance, for those that are worried about being possibly stung. I think the wasps + eggs were killed, but I left it and gave a second treatment at dusk to catch any late foragers coming home. 100% effective.
