Love this zapper!  Does this trick...its amazing what it can do.  Like the reviews say you don't put it next to you...move it away and if you want a good show put it in your eyesight.  I have one for the house and one for a cabin we go to...its like 4th of July...Make sure to get the Attractant and change it out every month.  Doesn't get them all but makes a huge difference.
