Great on wasps, dirt for bees. I used it to try and knock down a hive about 20 ft up. it DID reach, but didn't kill a single bee. Let me rephrase: it didn't have ANY knock down effect. However, that being said (no pun intended), the product is great for wasps. Now I await bee freeze
PT Wasp Freeze Aerolsol - 17.5 oz -- was purchased and used to kill a basketball-sized wasp nest in my front yard. Product worked as advertised, though didn't appear to work any better than the giant $3 cans of wasp killer available at any hardware or builders centers. Due to that, gave 3-star rating to this product due to it being way overpriced in my opinion.
I used the whole can and there are still a few yellow jackets building the darn nest so now I'm going to go to home depot and get something. I just have to kill those last few before I can knock the next off from where they're building it.
