   In New England, I have witnessed many instances of mosquitos taking advantage of this breach.

   Easiest to apply wide screen material across the bottoms of the joists, if possible.  Plastic screen with stainless staples. 

   Because of the roof and side screens up top, not much debris falls through to accumulate on the screen.  Should be ok for several years.

   Eventually they will probably clog up.  Worth the maintenance, imho.  Hate them mosquitos...

   Thanks, Corey. You are probably right about the debris. I guess it would take a while to fill up.

   Anybody in the Midwest?

   Stretch the screen on frames.

   Attach the frames to the joists in such a way that they can be removed later to clean and/or repair.

   Another approach might be to put a complete solid surface over the gapped decking.  Nothing falls thru, nothing flys or crawls up.

   Since it is a screened porch (protected from the weather) why not use T & G decking.

   Hey, Archy, that's a great idea. I could use Tendura because they want composite. Then transition to Rhinodeck on the rest. Oh, I guess I didn't say that the screened-in part is only over half the deck. (Another step back:) It's an existing room over an existing deck a story off the ground that's about to get torn down because of decay (the deck that is). The room stays and has to be propped up while the deck is being rebuilt. Pretty hairy, huh?

   Screen under a screened porch is very common here in the SE. There are 3 or 4 solutions, some already mentioned: 1) staple screen up under joists. 2) staple screen on top of joists and then apply decking (my least favorite, but common in new construction). 3) build screened frames to screw up under floor system - my favorite, but by far the most labor intensive.  Frames can be removed for cleaning.  Make sure you charge a premium for this method. 4) Homeowner rolls out in-door/outdoor carpeting.  Gives kind of a warm, homey feeling, if done right.  I've saw one with astro turf, which pretty much looked terrible.

   Thanks Matt for summarizing the options. The framed screens will be the most likely solution unless I go with T&G flooring. Fortunatly, the framed screens is the option the HO suggested. So it won't be hard to sell or bill for.

   > 4) Homeowner rolls out in-door/outdoor carpeting. 

   Doesn't this potentially hold water in contact with the deck and cause rot, termites, and mold?

   I'm in MA, have a screened porch (just the sides) haven't ever noticed a problem with misquitoes, but I suppose it's personal preference about that screen under the floor business.

   Thanks.

   I guess in this case, the situation is: the customer wants it, the customer gets it. I know I'd at least try a season without it just to see if it's necessary.

   Staple screening to the back of lattice and hang from deck rim joist to the ground or a pt board set in the ground.

   That's a good idea, Don, and one I will keep in mind in the future. I have in the past been asked to put lattice around the skirt of a deck. In this case, though, it's a second story deck that will be open underneath.
