It has a very short cord so plan on an extension cable with it.  It comes with a packet of mosquito attractant and will not do much against mosquitos without the attractant.  Note that use is prohibited "indoors" (occupied space) because of the nasty odor of the attractant and the UV lamp exposure.  But I have found it useful in the garage without attractant for all the other flying invaders (Florida) almost ever time I open the garage. The attractant was too much even in the garage.
