This summer, I have been stymied by where all the mosquitoes were coming into the house. Today, while holding for a call, my eyes sort of glazed over and I stared into the distance. I focused and saw it--the window was open over a half inch! And, that screen does not fit well unless I push it on tightly. I don't remember opening the window, so it must have been Spring when a breeze inside would not be humid and mosquito- and fly-filled.
That could also explain why it has seemed like the ac was not cooling or removing humidity! GAH!
The LED light on the back porch solved another problem--all the bugs drawn to light that come indoors when I open the door at night as I come or go are mostly a thing of the past. At first, I did not notice the lack of hundreds of flying insects. Then, one night, I wondered where all the bugs were. Since this light stays on all the time, I know I am saving money, too.
There are also fewer insects attracted to the lamp nearest me. Thank you, LED. With the window open and the screen so loose, more insects than normal came in.
I found LED lights for about $2 at Lowe's and bought a few.
Have you tried LED lights and noticed fewer insects are drawn to them at outdoor light fixtures?
