I don't know if this is the correct forum as I can't find any suitable tags.
We operate some of our equipment in fields inside tents. Our big problem is thrips/thunder flies. They somehow make it into the inside of the LCD monitors. This happens to laptops too.
It is quite amusing and an the same time annoying that these creatures crawl around inside the screens. If you press the monitor behind the thrip, it makes them move somewhere else. If you press too close, it squashes the thrip and its corpse will be there forever. Sometimes they just die in there.
We have a bunch of monitors with dead thrips inside which are for field use only. The main problem is when you look at data and wonder is that 112 or 1.2 because the thrip is over the 1 or . You have to move the text up or down to make sure - wastes a lot of time. Also when you are looking at charts, the thrip corpses obscure the display.
We have tried sealing the edges with duck/duct tape but still the little buggers manage to get in. The only way in I can think of is through the air vent which must not be covered.
I'm just wondering what I can cover the vents with that will still allow airflow but stop the thrips from entering.
