Karlsten Wasp Nest Killer Spray 300ml | Kills Wasps & Hornets | Fast Knockdown Formula – Kills wasps and hornets quickly on contact

I'm extremely allergic so my partner went to battle the wasp Queen that just started building its nest in our shed. It took just a few seconds of the spray and he could immediately see the behaviour change. Within next few seconds it just fell. This thing was about 3cm large! and it was defeated in seconds, while I hopefully gained a few more years of existence will less fear. I wish that there was a long or longer nozzle so that scaredy-cats like me, can keep a safer distance and fight back when these things attack. Also for those who are sensitive to scents - this has a very strong smell, but it works! So I'd suggest to mask up and keep distance or air out the room after use if possible.

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

It was good Used it a few times and no more bees or wasp Sad but when you get stung as you go out of the front door it is not funny

Excellent stuff. Expensive but only had to use it once to stop the wasps going into my wall cavity space. I have over two thirds of the aerosol left if I need to use it in a different location.

Quite small canister. Not used yet.

Very good product

Works as should

Good
