I had family down and had told my neighbors about this so they were all glad to sit around and chat without getting eatin alive. We have some woods around us, plus all the rain we have had, makes the mosquitoes so bad around this time of year. It really makes it hard sometimes to enjoy the evenings outside because of this. I like that this serves as light as well. It did a good job at keeping the 15×15 zone but of course the closer you were the better protection you got. The repeller mats last close to 4 hours each. I started out by putting it on the driveaway but noticed that we still had them buzzing around our heads although they weren’t biting our legs, so I ended up sitting it on a small table we had and that made the coverage a little better. It was super quick and easy to set up and start getting the repellant we needed. And we didn’t have to worry about being covered head to toe in bug spray either!
