Wasps making their way into my house via vinyl replacement windows?

What can I do to keep wasps/yellow jackets from entering my house through my vinyl replacement windows? I have even found them between the outside screen and the window when the window is closed, so how are they getting in?? The screens aren't torn either. For the price that we paid for them, I don't expect to have these things coming inside!!
