So it has the basic kind of 2 4 style decking on the floor.
How to keep bugs from coming up through deck floor.
If you re concerned about bugs coming up from the gaps between floorboards you may want to place a screen under the deck floor.
We have a porch that was built around an original deck.
This stops bugs from coming up through the floorboards of the deck.
Cover the gap between the deck and the ground with a skirt made of pressure treated or composite plywood.
My first thought was to lay marine grade plywood over the decking but given the potential for water to enter through the screen and lay on the floor i m a bit leery.
What kind of bugs and how high is the deck from the ground.
But there are little gaps in that floor and so even though the screens have been replaced around the walls of the screened porch and that s all tight i think maybe bugs are still coming in through the cracks.
Traditional decking has a 1 8 or 1 4 gap between boards which is more than enough room for mosquitoes or other bugs to crawl through.
The crawlspace beneath is open as it is a post on pad foundation.
The underside of a deck can provide a nice shady area for a variety of crawling creatures to make their home.
