Mosquitos are horrid little bastards; not even a mosquito's mother could find the little shits attractive
Even worse are those asian tiger mosquitos (Aedes albopictus IIRC), invasive with little competition here in the UK, aggressive feeders (only the females bite however), good at escaping from the Giant Fist Of Death(tm) due to their speed, and they are vectors for a whole slew of horrid arboviruses, including dengue fever, west nile virus, various parasitic helminths, chikungunya virus amongst quite a selection of other particularly unpleasant viral diseases.
I've seen a few in the house although never been bitten. They might be quick off the mark in feeding, biting and flying away, but not fast enough to get out of the way of a can of aerosol bodyspray with a cigarette lighter hovering in front
