I have a screen room built just below my Catbird seat. I put a ceiling fan in as screen cuts off the outside breeze. It also hurts the view and you can't shoot at Cowbirds. Actually, I built it first to sit in, and later came up with the idea of putting my out door Catbird place on top of it. I prefer outside.
I also have a portable screen room which is priceless when camping.

Sitting inside a screen room has many disadvantages.
I prefer not being in one.
The same is true for bugnet mesh clothing.

Deet was invented in WW1 and while I don't like it, decades of use by millions have shown it to be safe as have all reputable studies.
Toad, I believe you imbibe your share of beer. Have you ever seen what alcohol will do to living tissue? The better plan would be to keep the Deet and give up beer.

I find that the 20% deet is adequate for my needs. Even less is Ok if only out for an hour or so.
