Was the Certified Applicator for a central indiana city for many years, Mosquito control was part of my job! If you do not want them at your house go to lowe's or Wallyworld and buy a couple of real big/nice bug zappers. And then give them to a neighbor as a ? present with a big smile! Guess who will get the skeeters then! This info came from a professor at Purdue University Entomology dept where I studied. This works!
