Nylon Screen

Congratulations.  You just wasted 15 dollars more (you are only getting $200 for this, by the way).  The nylon does not hold up, flopping closed before you ever even apply the glue to it.  Worse, because you cut it to try it out, you can't even return it to Home Depot.  Would you like to try a different one?

Try aluminum screen.

Try 1/8" hardware cloth.

Or....

Give up and take the vacuum to them.
