I’m missing a solution in the replies. Create a last line of defence by using a mosquito net over your bed. They are available in quite large sizes so it shouldn’t be cramped inside.

Mosquitoes get in you house anyway. Use screens and so you keep the numbers down as low as possible. The chemicals are a possibility but sometimes also toxic for pets or even humans. The mosquito net over the bed keeps the last ones away while you sleep. I have mayby one mosquito a year that gets in.

Some water treatment facilities actually filter the water to almost to a demi water and add certain elements afterwards. So the quality is really stable and often better than bottled water.
