Different species have different attributes. The tiger mosquito (Aedes albopictus) from SE Asia is invasive in the Americas and carries nasty diseases -- yellow fever, dengue, zika, chikungunya. It's a highly aggressive biter, highly adapted to marginal environments, and can breed in a tiny pool of water the size of a bottle cap. It tends to be active in human-settled areas. If ever a mosquito deserved to be wiped out, it's this one.

I'm not sure about Italy; I imagine you have plenty of species migrating up from Africa. If you have a lot of mosquitoes, probably there is a water source they're breeding in -- a pool, an old tire, a nearby pond? If you can find a breeding source, dump a mosquito puck in it -- a safe algae that kills mosquito larvae.
