Black Fly Season in Maine

Yup, it’s almost that time again- Black Fly Season! You’ve been waiting weeks now for the snow to melt so you can see the ground, and tangible signs of Spring. Then, you remember the Black Flies!

A near panic ensues to clean up the yard as quickly as possible, to beat the hatching of those little suckers. It becomes the topic of conversation in the neighborhood, and at the local diner. “Wonder how bad they’ll be this year” is the chorus often heard.  The general consensus- if there’s been a lot of snow, regular rains in early Spring, and there is lots of running water during the melt off – there will be a “bumpa’ crop of black flies deah’ “. (This is my attempt at putting the local accent into print!) There is usually a window of 5 to 7 days after the snow has melted, and the ground is visible before the black flies make their debut.

Everyone has their theories as to when the Black Flies will begin to appear, and multiply!

If you have never experienced Black Fly Season in Maine, here is my best description. Millions of these tiny, flying, black insects swarm in giant clouds around your head. As you are distracted, swatting at the mass above you, individual black flies take the opportunity to make their way into your hair, flying into your eyes, up your nose, and even your ears! Rarely will you feel them bite. More than one will bite at a time. It is shortly after they’ve bitten that things can get really uncomfortable. Many people experience a welt, and itching. More severe reactions cause swelling. The discomfort does go away in 12-24 hours, but it is enough to keep even the greatest of outdoor enthusiasts inside on a beautiful Spring day.

Don’t feel forced to stay inside. Wearing the appropriate clothing, and effective natural Black Fly deterant are the place to start. Black Flies always like to go for the head first. They most often bite on the hairline, and the neck. Wearing a hat, or a bandana that keeps the flies from getting trapped in the hair is strongly recommended. For an extra line of defense spray head ware with natural black fly repellent to keep them from landing. Wear long sleeves, and long pants. For extra defense, spray your clothing lightly with a natural black fly repellent, and apply natural black fly repellent to exposed skin to prevent bites. (Disclaimer: Never use any repellents, natural or commercial, on the face or near the eyes, nose, and mouth!)

There are methods for repelling black flies naturally, without DEET or chemical based products. Clothing is a good first line of defense. However, on the really warm and sunny days after a long winter, who wants to wear long sleeves? Many claim eating copious amounts of Garlic will keep them from biting, but who wants to smell like Garlic for all of Black Fly Season? Your best protection is to use an effective, and natural repellent that will keep the black flies from biting!
