Rentokil PSW97 Wasp Destroy Foam Aerosol 300ml

I sprayed into the nest twice. We havent seen a wasp besr the area since. Result !

this product worked well was able to cut the nest away from the tree a day later with no wasp about

Our wasps had made their way inside a cavity in the woodwork on an ancient conservatory extension - so the big ladder had to be deployed and some plant surgery was needed to get a clear shot at the entrance. I read the instructions twice, prepared the field of battle, and went up the ladder dressed in a Wurzel Gummidge version of a bee-keeper's outfit, complete with improvised veil (fine mesh net curtain) draped over a hat, then put my kagoule hood over the top to hold it there. Was not sure how the wasps would react to foam - they have been less than welcoming when deep nests in a grassy bank near the house have had to be dealt with using petrol or kerosene, so I was taking no chances. Can't run like I used to....! So up the ladder at dusk to foam the entrance to the nest, and it all went well. Thick foam over the entrance, and the wasps were seemingly not interested in me, allowing time to descend the ladder safely. Next day they seemed poorly and activity was reduced - so we did it again that evening. Quieter still the next day, so we were gaining on them, albeit slowly. We knew which interior panel they were behind, so against my wife's advice I opened a tiny hole to fit the foam nozzle, and put a 2-second burst in there, then plugged it quick-smart. Noisy wasps! In the morning we could hardly hear anything inside the cavity and no wasp activity outside - another short burst through the hole was administered, and the plug restored. Next evening all was silent as the grave - but we put another burst in to be sure. Three days later, still silent, no activity. Success! So... this might also be made to work inside a brick cavity wall - with a long thin drill and some care. A lot depends on the situation. Our opinion is that daily foaming of the nest entrance would have done the job eventually, but would have needed at least another can of foam. It was working, just more slowly than the direct method. The foam nozzle is small, and only needs a small hole to squirt through - a suitable bit of tube to extend the shortish nozzle is handy for getting it in more easily and preventing the foam from escaping. Recommended for nests that are accessible by squirting &/or drilling. PS we had a go at yet another nest with Westland Eraza Wasp Nest Destroyer Spray (Aerosol) , with less than wonderful results, detailed in a review.

Brilliant stuff! The only thing we purchased that actually worked. You have to get fairly close to the best. We had a nest in an old armchair in the garden. All we had was a small hole the wasps were going in and out of. This filled the hole. We had to keep reapplying it...but eventually it worked. If you have a visible nest it would be easy as you can spray it from quite a distance..it shoots straight. Does work anyway...so give it a go 👍

Daughter had an enclosed wasps nest in a space in the porch. This stuff comes out like shaving foam, it stays awhile but then goes. I've used a couple of cans and the enemy are not doing well but are still about. I'd go for a different solution if the best is concealed

Had a major wasp nest in my shed and was skeptic to see if this would work.. what a great product killer them very quickly. Easy to use

Did the business Although I didn’t realise that it should have been used only when the nest is visible. My nest was in a conifer hedge and the opening was only about 2 inches wide and the nest was not visible. It did work though.

It works fine and is a simple can with a spray, so any monkey can use it if they have opposable thumbs. The foam kinda goes everywhere and dribbles down the can however so wear old clothes when using this. I sprayed a birdhouse which was where the wasps made their nest. It frothed up and covered the house and then I sprinted back inside the house before I got my ass stung to death. The next day the nest seemed dead, with lots of dead wasps outside it. I still sprayed it a second time and that was it. No more wasps.
