First, good post. Thanks.
Second, man, oh, man. If a person had any real concern about no-see-um's (biting midges), I certainly would NOT use normal window screen. Why? A short-ish story.
Grew up in Florida. Thought I was familiar with every biting thing that flies, crawls, or walks. No. Apparently, when I was a kid, midges weren't a thing. Probably thanks to all of the DDT they sprayed from the back of a pickup truck in my neighborhood. Made the kids laugh and chase it and run in and out of the "fog". But that's another story related to taxpayer-funded brain damage. Anyway, it killed lots of mosquitoes and probably midges if they were there.
Flash-forward many years to another part of the world. Still sub-tropical / tropical. Urban area. Concrete beehives masquerading as houses for people. Normal window screens. Actually, interior screened windows inside of a screened porch. Double layer of screen. Sitting at my desk, on the computer, something just starts eating me. Yeah, my ankles mostly and legs. Nothing there. I literally can't "see um". Disregarded and kept on working. One thing led to another, I end up with 20 or more bites all over my legs. Some bleeding. This happens again, and again, and again. Day after day. Season doesn't seem to matter much.
Turns out that those little *******s are drawn to CO2 (i.e, you), love urban areas as much as rural, come in through normal window screens, and seek out dark, cool places inside to live, wait, and probably breed (like under my desk). Oh, and a nice bonus ... whatever anti-coagulation puke they spit into your newly made skin hole causes the wound to take a long time to heal. Itching, scratching, new bleeding, more scabbing, itching, .... you get the idea.
A particularly insidious part is that, at first, it's like one of those really bad horror movies with a total budget of about $200. I'm getting eaten, bleeding, but nothing is there. No one believes me. Start to wonder if I'm going crazy. But the bites were real. And the solution worked ...
The only way that I was able to break the cycle was this:
1. Remove everything from under and around my desk.
2. Spray normal deadly toxic bug spray under and around there.
3. Put everything back and be very careful not to sit at the desk in bare feet (toxic absorption)
4. Keep the window closed right above the desk or the whole cycle repeats.
So, if you don't know about these creatures, really know them, consider yourself lucky. Mosquitoes are a nuisance and annoyance. Midges are invisible, flying piranhas that never leave.
If you think you'll be boondocking or even camping in their territory, do yourself a big favor and put the right screen on your windows. I know I will.
