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

This stuff works. We had a small wasps nest at the base of a tree, sprayed the entire can of this on it. Wasps gone. Seems to kill them on contact. All good.

Highly effective. Removed a substantial wasp nest within a couple of hours of application. Powerful spray gives you more distance between you and the target!

Would give no star if I could. Utter waste of money. This is neither foam or dust. More like a fly spray killer than nest killer. Spray absorbs into air or blows away. Didn't work. If I hadn't sprayed most of it would ask for money back under trade descriptions act. Not sure what the manufacturer was playing at. Don't be fooled by higher price, it didn't work for me.

Waited till dusk to spray the nest in our porch eaves. The contents came out as a large cloud nowhere near the distance stated. I ended up nearer a metre away. The wasps didn't like it at all and started emerging. We retreated. Two days later I finished the can but there was no reaction this time and I haven't seen any activity since. So I think that first dose did work. I don't think I managed to spray into the hole because I couldn't really see much with that large cloud of stuff but perhaps the ones that came out took the poison back in?

100% works !Was cut off from the garden by a nest of wasps living in between Patio steps. 5 second blast to the hive entrance and problem sorted ! Very fast and effective , would definately recommend . Was quoted over £200 by a pest control company

There was a nest in my outhouse, if I disturbed the door there were 100s of wasps which would come through a gap. I had no real idea where the nest was inside. Using this spray, over the course of 2 days I blasted the entrance. Most wasps died or became lethargic and easy targets. Once the numbers had reduced, I opened up and found the nest, it was large. Over 2 more days I blasted the nest 2-3 second squirts x2. This killed 99% of the wasps and the remaining few soon disappeared.I have plenty left in the can, I worked very well and I would buy again if required.

This product discharges like an aerosol spray which means the effective range is less than the 5 m claimed. I treated two nests which required multiple applications over 48 hrs. I don’t think I would buy this product again as it’s expensive and only effective if you can get close to the nests.After 72 hrs one of the nests is still active 🤷🏻

Really effective with long range expellant . Worth the money
