    Great article I just read as I had to retreat to indoors because of how vicious the greenheads are today. I thought that they arrived on the new moon the end of June & were gone by the full moon high tide in July, which is tonight! Guess maybe that’s not true, maybe it’s the full moon in August?? Sure is a miserable few weeks and they certainly are nasty bighters!! Very informative article though,

      Greenies are in season from the first full moon in July through the next full moon. This is an odd case wherein the Hebrew calendar, based on lunar cycles, always works — with greenhead season starting out on the 15th of the month of Tammuz and ending on the 15th of Av. If it is extremely hot weather I have seen them come out a few days early, but by that second full moon — 15th of Av — they are all done.

    I go to Cape Cod and some days green flies make it unbearable on Nauset Beach. Then we have Plovers nesting resulting in the closure of the beaches. It’s maddening!!

      Hi Helen… Do you know if the green heads are still bad right now? Michelle :)

    I live in South Jersey and the only thing that works for me 100% no greenheads is…when the wind blows from the East (off the ocean). This keeps them at bay, literally. Lol
    The absolute worst time to go to the beach between June-September is when the wind blows from the West (off the land).
    I believe you’ll be fine with little to no flys if it blows from other directions too. IF the wind changes from the West while your there, a few flys MAY appear but leave right when it changes again.
    Since I live close enough to the beach to drive down for a day trip, I just check my Weather App the day before and morning of to see which direction the wind is blowing. I guess for those of you who go to the beach for more than one day on vacation, this method won’t help you that much.
    In that case, I’ve heard from many people that Avon’s Skin So Soft works as a repellent…I think they even have a bug repellent that’s water resistant with SPF 30, and anti-itch relief.

    Just read the article. I hate these flies more than anything! They ruin our summers here in Newbury, Ma. The island referenced above is not Pine Island, but Plum Island. The greenheads near our home are horrible, and they have started early this year. We usually don’t see them for another couple weeks. :(

      It’s Pine Island. Follow Pine Island Road off Route 1A.

    Another reason to get a pool.

    Spectacular article!!
    I’ve never heard of greenheads.. Read about them in a book & googled it.
    I found this article there. At first, I was tempted to move on because I was just looking for more info on them..habitat, photos, etc.
    However, this article was so well written I had to keep reading..all 4pages!
    Nicely done, Ms. Annie Graves!!

    Living right next to a salt marsh with a pool,we are not able to use the pool the last two weeks in July each year due to these mini monsters. We actually go to the beach because they aren’t bad there. I wish these researchers could invent a safe repellent that works.
