Screened deck flooring - how to keep bugs out?
Hello, I will be having a deck built on the ground level on the back of my house, beneath my second story deck. I decided to have the contractor screen it in to keep out the mosquitos. Howevever, it just crossed my mind that can't the bugs simply fly up between the floorboards? What are some solutions to this? Instruct the contractor to place the boards very close together? Even then I'm a little concerned that may not be the best solution. Most decks I've seen, and my current 2nd story deck, has plenty of space between the floor boards in which to allow insects to fly between - which would defeat the screened in porche's purpose. Any recommendations?
