The best thing for wasps. I was told that it needs to be sprayed directly on the nest to work. I sprayed one bottle on the nest from a distance of 5 meters because I couldn't get any closer due to the roof, and another bottle at the entrance of the nest, almost directly at the entrance with the spray. The result after 2-3 days was that almost all of them were exterminated. There must have been 2-3 wasps left at most. But we're talking about a huge nest. Almost a meter. So there were hundreds of wasps

I bought it for wasps. It really sprays from a distance for safety. I sprayed the entrance of the nest for 4-5 days, 2-3 times a day at various times. Those that the product hit died immediately or at most within 5 minutes. The others just got enraged and when they calmed down, they went in and out of the nest as if nothing was happening. The canister emptied and I called a professional team. The team that did the job effectively said that they use the same active ingredient (pyrethrin if I remember correctly), only the spray contains 0.1% while they put 10% in the mixture!!!!

Excellent for wasps!!! The only product I managed to find and it saved me.... It exterminates the wasp nest when they are all inside.
You also spray in dangerous areas and the wasps don't come near there... Just after about 10 days its effect wears off and you need to spray again.
The only negative is that with 1-2 sprays the whole bottle empties immediately, so never buy just one. It won't be enough for you...
