Finally, a day without rain this weekend. My husband and I wasted no time getting outside to do some much-needed yard work and the black flies wasted no time making sure they got a good meal out of us. I tried to get into the zen of pulling weeds, but I guess there’s nothing zen about jumping up and down, flailing your arms about and swearing loudly that you detest the little #%@s!
When I finally gave up and escaped indoors, I discovered more than a dozen bites on my neck and shoulder, along with a couple more above my eyebrows and under each ear. At least I didn’t find any ticks crawling on me as well, but once I saw the bites they suddenly began itching. They still itch. Next time, I’ll be better prepared!
Black fly emergency preparedness
- Cover up well. Black flies like to crawl up sleeves, into waistbands, under socks and up pants
- Wear light-colored clothing
- Wear a bandana around your neck
- Wear a shoulder-length head net
- Work outside in the early morning or late evening when they are supposed to be less active. (Of course, you have to worry about the mosquitoes at night.)
- Try using a mosquito repellent, although you may need to keep reapplying
Black fly bites hurt because the fly cuts a hole in the skin and injects anti-coagulants to make a larger pool of blood from which to feast. GROSS, I know! Some people don’t seem to be bothered at all by the bites, while others are more sensitive. When my daughter Katharine was a toddler her eye became so swollen from a black fly bite we took her to the ED. A little Benadryl and she was fine but what a sight, poor baby.
Robin says there is no precise end to black fly season in Maine, but they tend to go into “dormancy” by mid-July. Unfortunately, they come back for a spell in the fall, although usually there are fewer than in the spring. She also told me, “A hard winter doesn’t affect the number of black flies that hatch in spring. They breed in running water, which seldom freezes completely and they can survive in water as cold as 32 degrees.

Even so, black flies are mostly a nuisance, but in her Black Fly Report Robin encourages us to “Get out and enjoy Maine nature — even the black flies. You can tell everyone you’ve experienced the black flies and lived to tell about it.”
That’s me! And now, I’m going to soothe my itchy bites for the umpteenth time with a little witch hazel.
