Hundreds of dead mosquitoes on the office door..?

Question

I got to work around 7 am this morning. On the door that leads into the office building (there is a small window on the door and the light in the office is kept on all night) I noticed about twenty mosquitoes on the glass part and realized there was close to 100 on the door itself and several hundred more on the wall surrounding the door and several hundred I noticed dead on the ground. I also believe over half if not all the mosquitoes on the door/wall are also dead. The office building is only a couple weeks old and the office employees are kind of worried about this. Does anyone know what is causing the mosquitoes to attract to the building and why are they all dead?

Answer 1

Whatever paint your using, or material that makes up the door/wall, attracts the mosquitos. So when they come, they run into the door and walls and windows. Most of them will not die, but become very hurt/injured. The ones flying faster will accidentally commit suicide.

If you have a new office building, check what type of material it's made out of. If it's certain types of plaster of paris or drywall, it may be attracting the mosquitos. Or the office could just be shiny and attractive at night, since bugs are attracted to the light.

They'll be dead if they keep crashing into the surfaces of your office building, so no worries there. Just be careful of whatever the building has, since it really attracts mosquitos.

Answer 2

many of the insects/mosquitoes would be flying toward the glass window (lighted) at night, and would be killed or injured upon hitting the glass.  it is normal,  and well documented

that insects do this -  flying toward and into lights at night,

that would present no hazard to the humans at all.

(except due to so many dead insects)

Answer 3

I'd guess... that the volatiles in the paint used on the building's door and walls are 'off-gassing' and it's somehow attractive to the bugs, but so much so that they're staying there instead of finding food or making them over-exert to death or resulting in poisoning..... something akin to the fumes that escape new carpeting.....now, since the mosquito-attractors use co2 to lure them to their deaths, perhaps... maybe... the fumes are not dangerous to humans.... perhaps... maybe... but I'd hope someone has a good look at this and don't just brush it aside...............
