No, they aren't alien invaders. I pretty much have to shower in repellant in order to avoid being sucked dry by these blood thirsty mosquitoes. Unfortunately Off for Outdoorsmen not only repels the mosquitoes but butterflies and dragonflies as well. Needless to say I was thrilled with my shots yesterday. By the way, that picture is about scaled to life. When they swarm like that, they really do sound like a squadron of fighter planes. Its advisable to cover your nose when passing through a swarm like this. I'm sure you can figure out why.
The only thing worse than hearing a mosquito buzzing around your head is hearing a mosquito buzzing around your head and then suddenly not hearing it anymore. That drives me nuts! When they are buzzing at least I know they are still flying. They don't buzz when they are feeding.
Ugh! Just looking at that picture makes me itchy.
