Ordered 2 aerosols of Wasp and nest destroyer. Unfortunately the delivery company let them down and as soon as I contacted them 2 were sent special delivery arriving the next day with an apology. Can’t fault such good service. Thank you

Unprompted review
I don't recommend it
I don't recommend it. They called to tell me that the product I ordered was out of stock, but that they would send me another product with a different sticker that does the same thing. I tried the product, but it doesn't work. Wasted my time. Disappointed. Rubbish

Hi Marius, we called you before dispatch and you agreed to receive the alternative product. Rather than reaching out for support — which we always provide, along with full refunds if needed — you chose to leave two one-star reviews under different profiles. We’re always here to help, but posting duplicate reviews after agreeing to the swap doesn’t give a fair picture of the situation.

Karlsten long distance wasp killer has done the job, getting rid of a wasp nest that was in my loft, and being accessed by wasps under the roof eaves. I sprayed the place where the wasps were landing and crawling into the eaves, and they are gone (it took a couple of days before no activity). I wore a mask and gloves when spraying, and glad I did, as I was expecting a spray strength similar to a deodorant bottle, but it was much stronger than that. Would definitely use again, as so easy to use for awkward/high places.

Great results…
This powder is much more effective than other powders I have used to deal with ants under a paver brick drive.
The ants have yet to reappear!

It did not work at all. I tested bugs covering with powder & they are still walking 5/6 hours later

Hi there, thank you for your feedback. The powder does take time to work — it isn’t an instant kill product, but works by sticking to the bugs and dehydrating them, which can take 24–48 hours. We’re always happy to offer guidance on the best way to apply it for effective results, and of course we provide full refunds if you feel it hasn’t worked as expected. Please don’t hesitate to reach out — we’re here to help.

Kirsten Bird Spray attracted Pigeons rather than repelling them. This is why only 1 star. The product has a picture of a pigeon on the front but don’t be fooled by this I got double the amount of pigeons after spraying.
