Karlsten Wasp Nest Killer Spray 300ml | Kills Wasps & Hornets

Thank goodness it did the job. We had a large wasp nest in our shed very dangerous in small space. Expensive but worth every penny NO MORE WASPS TO BE SEEN .

Amazing product, cleared wasp infestation / suspected new nest within a few hours. Worth every penny! Just follow instructions, spray area for 10 seconds, leaving plenty in the aerosol for future use.

This product did the job for wasp nest on my roof

Had two wasps nests, one took a single 4-5 second spray and the other took two similar sprays. Effective, easy to use and definitely cheaper than getting someone round.

I could not discern any difference at all between this and my previous spray obtained from the local corner shop for less than a quarter of the price. Despite close-quarter spraying in my loft there is no 'quick kill' of either flying wasps or those in the nest. At this price I expected more and was hugely disappointed.

We had an external hole just above the front window within the wood that we could see wasps going in and out. We considered just filling in the hole but read that the wasps will just eat their way out through the wood (or plasterboard, cavity insulation or whatever they are trapped next to) and usually this means eating their way out into your home. We therefore bought the Karlsten Wasp & Nest Killer and waited until evening and sprayed a liberal amount directly into the hole. This definitely worked but we were still left with some activity. We repeated the sprays an hour later, the next morning and again that night. All in all, 4 doses totalling half a can. The smell, if used outside, is negligible. The smell, if used inside, is much more apparent and I would be inclined to leave the room aired and closed especially from pets and children. After 4 doses all movement and noise stopped and we bunged the hole with sealant. Since then we’ve had no movement and no stray wasps hanging around. Good value for money and reliable. Would definitely recommend and buy again. Edit - one week later - still no wasps

Does what it says on the tin, very well.. killed bees very quickly. Quick delivery

Good
