I'm thinking ahead a little here, but what does everyone do to escape the black flies once they come out? I'm guessing that rope climbing isn't terrible at some places if there's a breeze, but bouldering seems nearly impossible unless there is a good spot that the flies don't know about.

I would also love to hear a good recommendation or two.

From my experience, roped climbing is just as bad, if not worse, than bouldering. I've even been destroyed by black flies up on Cannon--and I was sure those little fuckers wouldn't want to fly that high up and brave the breeze.

Belaying is what sucks big time. At least the climber is moving.

Multipitch seems like the answer, but when you're imprisoned at a stance while belaying you have no fucking escape.

Head net for the belayer might be a good idea. A better idea is to not go climbing.

During the month of June, when i used to live in the 'daks i would head west for about 3 weeks.

Black flies do not breed at elevation (only in running water, and there's more of that the lower in elevation you go). They get carried to the top of cliffs and mountains on the wind, then settle there until their life cycle ends. That's why they're common on mountains and cliffs.

Windy and cool days are the best prescription. Doing climbs that are high in elevation will help increase the odds of wind and cooler temps. Otherwise - I always bring and wear a headnet, and apply lots of deet.

For lower elevation (bouldering/top roping) we've had some success using this:

Just don't use it on a windy day because it moves the cloud of repellent away from you, rendering it useless. If it's that windy you shouldn't need it anyway.

slap this laser thing on your head lol

i heard that pee keeps the flies away. Maybe you should try "that" shower.

I climbed almost 30 years in new England.. I know its evil stuff but only Ben's 100% deet ever worked. Just keep it away from your nylon.. and your eyes and water and..

Insect shield clothing works well, socks to bandana. And we've had good luck with some of the less-toxic insect repellent lotions. Breeze is definitely your friend. Of course, you could just come up here to northern Minnesota and go paddle around in circles in a canoe: the bugs leave you alone while you're on the water.

Cigarettes, stogies or jazz cigarettes if you aren't into tobacco. Tuck in your clothes, tape if necessary. Gloves and a headnet for maximum relief. A lot of people work outside year 'round ya know. They use a technique called "suck it up Stacy"

Exactly John. Suck It up. I work outside and have been backpacking/fishing/kayaking/hiking/biking for years and black flies never detered me from anything
