Bests & Worsts Reviews from Amazon

I can say for 100% certainty that this product does NOT kill on contact, as advertised on the packaging. I'm currently in a war with a hornet, and ordered this. The first hornet I wasn't certain that I actually got with this spray. I ended up murdering him with a pool net. The second hornet, I have for certain hit with this more than once. Yesterday, I got him at least two times with the spray. He has returned today. I have sprayed him once today and he's flown off. I also had a couple wasps in this war, and have hit one directly on the ground and the other directly on a surface he landed on. Both wasps have flown away too. I did spray a small nest that I haven't yet attempted to remove due to the not killing on contact factor. I attempted to spray this around for a barrier to see if it was a deterrent to hornets and wasps and I can say with certainty that it doesn't act as a deterrent. I have other products from this brand and have been happy with the results of those however, due to my reasons listed above I would not recommend this product.
