It is very strong and sprays several feet. It is very easy to use and works instantly so there should never be a fear of the wasp not dying. It does have a little bit of a chemical smell but it doesn't last very long.

The Spectracide Wasp and Hornet killer is an excellent spray and very effective The product can spray with an accuracy that there is no way to miss. The other awesome thing that I can say about this product is that it kills instantly. Luckily it is safe for use and it is not expensive. I highly recommend if you have a wasp or hornet problem.

I purchased the his at Home Depot and it works great! It is reasonably priced as well. This spray is easy to use - it has a very long spray range and is highly effective. I was able to eradicate my whole wasp problem! The spray coats the nest and then 24 hours later you can knock it off and it and all the eggs/wasps are dead.
