You have to make sure the product is relatively fresh (not more than 3-4 years from the date of manufacture). If it's fresh, it will flat out kill the bugs that it says it will kill. I got rid of a yard full of spittlebugs by using the high end of the range suggested to treat. It seems to do a good job on Southern Pine Beetles, too.

I am still waiting on the receipt of this product, therefore, I am unable to provide a product review at this time.
Best product for pest and best site to order from.
