Over the years I've used netting of different types etc. in jury rigged attempts to keep bugs out. I have to say that the bi-fold screen door on my
Scamp is absolutely perfect.
Both in ease of operation and for keeping bugs out.
There are some ads for netting with magnets closing a vertical center seam but I don't if they're as good as the bi-fold door.
Photo shows the door and how relaxed I am knowing the bugs can't get in
