Well, look at it this way. Are you tagging and following each mosquito from egg to death? This mosquito didnt likely die today. It has lived a week or whatever and its just because you have a steady stream that there is a never ending supply.
Another possible reason is with the recent extreme heat, they heat stroke out at the window and die there.
Could be mostly males and a lack of food in your place. There are multiple reasons, but i doubt very mu ch they emerge as adults and die the same day…
Genuinely perplexed. There’s really no way enough air would be recirculated from a neighbouring apartment, if they were running one of those plugins, to kill so many is there? Do you smell cooking smells from neighbouring apartments? Also what floor are you on? If it is 1 or 2nd floor maybe the post about sewer spraying is on the money. But I’ve never heard of this happening.
Wild theory, for entertainment value more than anything else. Maybe they came around spraying and somehow sprayed a shetload of insecticide in the air intake on the external ventilation unit. Or maybe some chemical happy resident dumped some insecticide in there? I noticed in Taiwan, often these units are out almost on the street, in very accessible places.
