Wasp Nest Killer 300g - Professional Strength Wasp Nest Killer Powder for Fast Acting Treatment of Wasps & Hornets Nests | High Strength Wasp Nest Destroyer for Indoor & Outdoor Protection

The cap was difficult to get off and wasn't sure if the tip should be cut off. No instructions for how this should be done. I did manage to remove the top and under the top was another nozzle that you cut the tip off. The cap then fits back on and clicks to stop accidental spills. Not as difficult to remove once this has been done. The wasp nest was under ground in the garden so I placed the nozzle close to the opening in the ground and squeezed, the power went into and around the hole. You could clearly see the wasps had the white power on them leaving and entering the nest. Job Done! Didn't see anymore wasps after 24 hours. The instructions says to put more powder after a couple of days and this will be easy. The wasps original stung my dog while it was playing with its ball, we didn't know it was there until then. Really please that they are no longer.

I did 3 wasps nests with the one bottle. Really effective. Happy with the product for the price. Each nest was inactive within 24 hours. I think the 3rd nest would have buzzed off if I just showed the bottle!!

Seems to have done the trick on a below ground wasp nest.

It takes 2-3 applications using a wand sprayer to get the powder atomised when needing to spray into a hole in the wall. However the product works - it just takes time.

Good product, don’t like the smell but it works

Works well with wasps. It will not discharge by squeezing easily if it is higher than horizontal. Then best to open it and inject with a tool. Make sure to wear a mask as the dust is nasty when inhaled.

Wow, this is good stuff - only needed three puffs of powder squirted into the cracks where the wasps were coming and going. Activity had been increasing for some weeks, and had tried to use a foaming nest killer, but obviously wasn't able to get to the nest itself and the wasps just carried on. The issue here was that their access was just above the front door and with work currently being done on the property - it was becoming an issue. Directed three puffs of powder into vicinity of cracks towards end of the day, and the next morning - there was no sign of any further wasps activity! Result :-)

We had a couple of wasps going in and out of a crevice in the bricks, not seen a lot of them but didn’t want them to start building up, so we put the powder in it and we never saw them again 🤞
