Do you smoke? Cigars or a pipe? Nicotine is an OUTSTANDING bug repentant. I smoke cigars, I take all my buts and put them in a coffee can with water and use the water to put into a spray bottle. Spray it on all the surfaces, not yourself. I live right by the Alabama river and I have no mosquitoes biting me ever. I even spray my garden with it. If you dont smoke. go to the gas stastion and get a few Swisher or Phillies and boil them for a few minutes. Spray you door frames and window frames. Its natural and nontoxic and doesnt have an odor when dry. I promise you it will be effective.
