Any suggestions as to how to enclose my deck floor from underneath? Deck is 12ft above ground. Goal is to keep the bugs out. The deck will be enclosed within the next 2 weeks. Thanks.

I have screened them from underneath, stapling the screen to the joists.

I do the same but add 1/4 x 1 1/2 inch strips on each joist for added support and a finished look.
