We don't get many noseeums on our waters, but along some Bay Island shorelines green-head flies are more than a nuisance. They seem more prolific in areas highly populated by deer, during hot weather - mid August being the peak. Since they literally tear the skin's surface open to suck blood, their bites are very painful.
Of course a poor defense against noseeums, but one great weapon I have found to combat these greenheads, is my trusty flyshooter.
It's deadly, fun and accurate. These bloodsucking flies are constantly seeking shade against the sun, so when they find their way into our pilothouse and cabins, the target shooting begins. An attached string makes reloading fast and easy. Mysteriously though, they disappear at night - replaced by mosquitos.
