Mosquitoes in apartment lift

There are just too many mosquitoes which have decided just to enter the lift especially in the evenings. It's an old school grill type lift, it has a light and a fan, which turn on automatically when a person presses any lift button. And Immediately when the lights and fans turn on, the 100 odd mosquitoes get dispersed from their place and they start flying all around the lift. They try to enter every hole visible of the human body ears, nose, mouth, etc. 👀. The neighboring parking region around the lift doesn't have so many mosquitoes, they just wierdly stay in the lift. Is there any remedy you've come across? My mom has tried putting 5-6 lavangams in a half cut lemon. The first day of doing that, all the mosquitoes left. Maybe it was fumes or maybe they were traumatized at the idea but my mom celebrated the win. But after 2 days I think all those mosquitoes which left got their neighboring clans to join them in resistance and now there are more mosquitoes than ever, like rn there are at least 100-150 compared to 20-30 before. My mom's method toh looks like it has done exact opposite of what she tried. It just looks like they're taking revenge against her for attempting whatever she did. How do I undo this? All the tenants are facing this problem since it's a common lift and there are little kids staying in the apartment. Looking for a long term solution.
