Live in a small condo and get the occasional mosquito but lots of the smaller biting midges (blackfly/sandfly?). We have a racket that kills them when we can see them but I’m looking at the purple light devices all over Lazada. Some use a fan to trap and dry out the flying insects while the rest just vaporize them with a high voltage mesh after attracting them with the purple light.

Do any do these devices actually work? Are the fan ones better than the zapper ones?
Thanks!
