Hackberry Gall Psyllids?

I have a hackberry tree right in front of my balcony and in september/october my door screen is COVERED with them, and if I kill them or vac them, others will return as soon as a day is warm. What I noticed is that they tend to love to land on the window/door insect screen (we are talking about a thousand at a time) while only a few land on the actual gl door next to it. So what I'm thinking is, would it be a good idea to remove my insect screen before they become active in sept/october, or will I just make things worse and they will land on the gl door itself and risk going through into the house even more? I'm perplexed by their behavior on why they tend to land on the insect screen in much bigger amounts than on the actual gl door next to it. Now it's too late for this year because I"m not opening my door. But I'm just wondering if anyone has any solution, whatever it may be. Are there screens that allow air to come through but are not the typical insect screen with the fiber line scares? Maybe something like transparent but the wind goes through anyways, maybe they won't like to land on it, but it would still work for ventilation AND preventing insect?
