KarlstenWasp & Nest Killer Spray | Maximum Strength, Fast-Acting Formula | Kills Wasps, Hornets & Nests Instantly | Long-Lasting Indoor & Outdoor Pest Control | 300ml

After reading reviews on some other wasp killers - which didn’t sound effective, we chose this one. It was a bit more expensive than other brands, but it really works very well. We had massive wasps in the loft and after two separate sprays, they were all gone. It also smells quite pleasant and the smell dissipates very quickly. So it doesn’t stink your home out! We still have about half a can left. Would recommend.

It did exactly what it said on the tin

I discovered a small wasps' nest in an outdoor cupboard.After looking at the reviews of all the various wasp killers on Amazon, I decided to buy this one.The day it arrived I sprayed the entrance to the nest with a short burst, and repeated this for 3 days, just to be sure.On opening the cupboard I found lots of dead wasps and no live ones, so I was able to remove the nest.This contained a piece of honeycomb containing a number of dead wasps, so the spray was 100% effective.

Initially this was fantastic.. we sprayed the nest as directed and no wasps in the house but by 6am the next morning, there were flying wasps in the houses again... sleeper, slower and easier to kill but 5 days later and there are *still* 12-15 sleepy wasps a day and one of the children was stung by one.... I wouldn't buy it again

I used this to clear out a wasps nest near the front door. I sprayed the area and entrance on two consecutive days and have seen no wasps since. Simple and effective.

Used this a couple of years in a row now for wasp nests inside airbricks, at the back of the shed.. under guttering etc. Just make sure your area is well ventilated.. not the cheapest product but really effective and seems to leave behind an invisible coating which lasts for a while after use.

It kills wasps

Wasps had built a nest in between two sheds where we had a gate into a bridle path behind our house.Every time you shut the gate the wasps would get annoyed, making the journey to take dogs out for a walk perilous!Plucked up the courage, got everybody to stay indoors and ‘injected’ to spray into the gaps where the wasps were flying out.It did a great job and very quickly the nest was dead and life could resume :-)Used up the entire can, making it a single use purchase, but it did the job and it did it quickly.
