I heard mosquitos are attracted to dark blue colors (like blue jeans) and clapping sounds. So the more you swat, the more hear you and come your way.
And there seem to be a lot of products out there that are suppose to keep mosquitos away or outright kill them. I read about one that attracts them into a lantern and zaps 'em like a bug zapper. Dragonflies are their natural enemies, and someone invented a device that simulated the sound of dragonfly wings so that skeeters would hear the sound and stay the h.ell away from the area.
There was also an acquantance of mine from the US that owned a farm. He said there was a swamm right beside it, but he had a large group of bats living in one of his barns and during the summers, he had seen almost no mosquitos in 10 years. Eventually, someone bought the area with the small swamp in it and dug up the area. The bats flew off to better pastures and within the year, his farm was completely overrun with mosquitos. He said he thinks either the bats kept toe mosquito population to virtually nil, or the mosquitos have a way of hearing bat sonar and knowing to stay away.
Maybe Calgary should look into importing a bunch of bats.
