Wasp and Hornet Killing Powder - Wasps nest Killer as Used by Professional Pest Controllers

Works well

Some difficulty forcing the powder into crack in wall. It did work though. Foam didn’t

I was able to direct this powder onto a wasp nest (under the root of a tree). Thankfully it worked quickly and I filled the hole in with gravel.

Worked in the end, had to use a separate puffer to apply but did kill the nest after a few treatments

I used this to kill off a wasps nest that was forming in an air brick. I just sprayed some into the main holes they were using and over the course of the next 24 hours it mostly killed off the nest. The nozzle can be cut to suit, depending on how much powder you want to deliver in one go.One complaint from me is the cap was very difficult to remove and whilst giving it some force it cut into the skin on my fingers .. so I'd recommend using gloves.

Maybe an error in application by me, but it only temporarily subdued the nest before It was business as usual. Ended up getting an old boy from the village who bungled some jollop on a stick, shoved it into the nest and that was very quickly that.

The wasp nest was difficult to get to but using the powder and foam they were killed off.

i had a sizable wasp nest in the sofit area of my kitchen extension used this stuff in the entrance to the nest 3 nights running and still lots of wasps about so on the 3rd night i put this in i also sprayed a tin of fly spray into the wasp entrance that evening and the next day all dead so it was either this expensive powder that done the trick or a 50p can of fly spray
