Query: Don't even bother

We live near a protected marshland park, and so our yard is loaded with mosquitoes. I spread this according to the directions throughout my half acre yard, spreading it with a fertilizer hand spreader. Even after waiting a few days, the number of bug bites I was getting after was pretty much the same as before. I saw no decrease for my time, money and effort, and I really wanted this to work.
