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

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.

Probably longer than a 4 seconds burst at 4am but made sure after being stung 15-20 times but did the job

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

Fastest way I've blow £20 in my life!Got a bunch of wasps trying to build a nest in an old vent side of the house.Thought this would do the trick considering the cost.Firstly, the can lasted about 10-15 seconds before it completely ran out!Secondly and more importantly, the effectiveness lasted about 5 hours before the wasps continued again.Because there's no foam, the spray just vanishes after a while.Weather conditions don't matter either as I did this on a hot sunny day with no wind or rain.Unless your right on top of the nest (minimum 1 metre) then don't bother with this product!

Great only needed 1 squirt... but did another 1 day after just to make sure although it didn't need it

Killed wee beasties instantly. Ordered more and several nests

The makers claim that you can spray at distance from the nest. Not so good if the location is a bit breezy

Very effective and fast
