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.
