## Overview

Rentokil PSW99P 300g Wasp Killer Powder harnesses the power of permethrin to swiftly eliminate wasps in nests, especially those hidden in inaccessible spots like roof cavities and tree holes. Designed for easy application in home and garden settings, this professional-grade powder offers long-lasting protection and multiple uses per pack. While highly effective, users should apply with caution due to its toxicity to aquatic life and potential allergenic effects.

## Description

Kills wasps in nests with permethrin. Ideal for inaccessible areas like tree holes, roof spaces, and air vents. Easy to apply for home and garden use.

Review: Excellent product that works, but beware of the smell dead wasps can leave...! - We found we had a wasps nest in our cavity wall after noticing wasps leaving and entering very frequently underneath a small piece of cladding on the roof of our extension (fortunately we have a window that leads straight onto it so it made it easy to do). The wasps were only exiting in one place but were gaining entry all the way along this piece of cladding. We applied the powder all away along, and the next day saw very few wasps, however as the week progressed it got rather busy again outside our window, so we re-applied the powder very liberally! The powder has remained there and around 10 days later there was a lot of activity again, however the powder killed it off. I think if it's a relatively large nest (which this was), it does take more than one application, as there are still grubs etc. in the nest, however I'm now confident we've sorted the nest. The only couple things I'd say, is after the second application and being sure the wasps nest has died off, we now have a horrible rotting smell in our kitchen (room below cavity wall they had found a home in), and we're sure it's the wasps nest as have read of others experiencing the same thing. This smell is absolutely horrendous and despite airing the room, using airfreshner and deep cleaning the room, five days on and it smells worse now than it did. If you have a large wasps nest in a location that backs onto a room you use a lot, just be mindful of this, as I can assure you it's an absolutely disgusting smell!!! Hoping it'll clear soon as the wasps finish rotting away (ugh!) Also, this product is very poisonous to cats, and should not be used around them. Fortunately our cats do not go onto our extension roof, so we've been safe to use it, but if the nest had been anywhere else where our cats do go, I think we'd have called a professional it. This is a great product at a great price - it's worked brilliantly and we've got loads left over for use again if we ever need it - given how much we put down, I'm amazed at how much we've still got left. Definitely cheaper than getting an exterminator in!
Review: Great - Worked after 2 applications - it's not easy to apply under roof tiles when the wasp nest is inaccessible but getting it around the entrance was great and didn't disappear like the foam

### ⭐⭐⭐⭐⭐ Great
*by J***Y on 19 July 2025*

Worked after 2 applications - it's not easy to apply under roof tiles when the wasp nest is inaccessible but getting it around the entrance was great and didn't disappear like the foam

### ⭐⭐⭐⭐ It worked after a few tries - see photo
*by A***H on 16 August 2022*

It worked and got rid of the wasps which were nesting in the eaves above my front door. See photo for remaining powder after wasps have gone. It was tricky to use when trying to puff the powder upwards into a small hole in the eaves while at the top of a ladder. I could imagine this would be very easy to use if at an angle where you could aim downwards instead though. It took three tries on separate evenings but I finally got enough in and around the hole to finish the wasps off - the trick is to motion the bottle upwards quickly while squeezing as much as possible! It could have done with more of a spout or something similar to make aiming at a small hole easier, however it did its main job in ridding us of the wasps so I'm happy to recommend it.
