Karlsten Hyper Power Wasp Nest Killer & Hornet Killer 600 ML - Gold Standard High Strength Long Range 5 Metre Spray for Indoor and Outdoor Wasp Nest Removal - Wasp Killer Spray

Did exactly what it said on the can.Nest in summerhouse roof, very active with lots of wasps.Spray delivery was powerful and effective.Following day zero activity and none seen since treating nest.Worked perfectly for me.

100% works !Was cut off from the garden by a nest of wasps living in between Patio steps. 5 second blast to the hive entrance and problem sorted ! Very fast and effective , would definately recommend . Was quoted over £200 by a pest control company

Would give no star if I could. Utter waste of money. This is neither foam or dust. More like a fly spray killer than nest killer. Spray absorbs into air or blows away. Didn't work. If I hadn't sprayed most of it would ask for money back under trade descriptions act. Not sure what the manufacturer was playing at. Don't be fooled by higher price, it didn't work for me.

It did exact,ly what it says ,sprayed from 4metres covered the nest no more wasps, good value for money

Why did you choose this product over others?:EffectivenessSpray effectiveness:Spray effectiveness, much more effective than a powder as most of the nests I deal with are in the roof/eaves when the powder container needs to be held vertically to some extent or horizontally and the powder therefore doesn't come out!

Used at dusk from about 2 metres away this was completely effective in immobilising all the wasps in a relatively small (8cm) nest. I have used foam products and found they do allow some wasps to escape and attack the user of the spray. This product immobilised the wasps immediately, probably because of the solvent spray rather than the weak insecticides amateurs are allowed in the UK. I was impressed and will use this product again.The 4m spraying distance and the number of nests that can be treated are probably on the optimistic side, but I took this into account when choosing and assessing the product.

Gave it 3 goes but unfortunately didn’t kill them all - did slow them down. They were in under the eaves of the roof so it could well be that I couldn’t get right into the nest so no fault of the product

We had a wasp's nest in the top of our porch, we could only access the nest from a small hole so we sprayed into the hole for about 6 seconds late at night when the nest wasn't active.We haven't seen any wasps since 👍🏼
