I think a much better way to get rid of mosquitos in a local area, but not of everything else, would be a laser turret ...

Unfortunately not market ready, yet ...

edit: bat boxes, water-fish traps and having birds around will certainly reduce mosquito population ... but there will be still lots of them around. A laser can take them (allmost) all out ...

Oh and about the water: if you just have open water around with no fish in it ... then the mosquitos will love that, btw.. So taking care, that there is no open water around, when it is hot, helps also a lot ... but I still want my laser turret.
