A Gnaty Problem

Twice now, we've been on Georgian Bay in warm, still weather and have been swarmed, attacked, invaded, infested by clouds of gnats. This last episode occured and millions of these things descended on our boat from the top of the mast to the deck and from stem to stern. They hung around for an hour or so and then left, leaving behing the corpses of tens of thousands of their comrades. The attached image is of our transom walkout from above, after the survivors left. We pulled into our anchorage and spent the next hour scrubbing the boat (yes, a traumatic episode for me) free of these corpses.

Has this happened to anyone else and, more importantly, is there a cure/prevention for this.

As near as I can tell they have a life span that requires a stop watch. The things just die where they stand or sit in this case. It's the curse of living too far north. They tend to go away in the fall. I didn't think they lasted this far into July though. When do the black flies leave or at leave abate?

This was on July 11.

Blackflies are done by early June at the latest, just in time for the mosquitoes to arrive. Then come the horse/deer flies. Then comes winter.

Sigh...

At least we don't have jellyfish or sharks.

A flamethrower? I wonder if something like a propane torch might at least scare them off? Maybe lighting a big open flame on the barbecue? Pull up and re-anchor and hope they don't follow?

I wish I had a better idea for you.

Could you run a large fan and blow them away?

The silly dead wee beasties are wet and sort of stuck to the boat. Fan won't work but the flamethrower idea does intrigue me.

I wonder what the insurance adjuster would think...

Don't worry. Sex, politics and religion...

Dave,

I'd much prefer sharks. Even jellyfish, since I can escape them by leaving the water. The bugs are the only thing that keeps me away from Canada in the summers!

We get these in Chicago as well. When we used to keep our boat on a mooring, occasionally the tender would bring you alongside and you wouldn't know where to step as you could hardly see any boat.

And, then they seem to leave behind a thousand green spots. Nasty.

When sailing with a light offshore breeze at night these things bump into your head and face by the thousands.

At the dock, where ever there is a light, there is a swarm of millions of them. I say "bring back the bug zappers" as they sure do seem to like the light.

Because of these swarms, every dock and boat in Chicago gets covered by a full compliment of spiders that grow into the size of small rodents throughout the season.

I know what you mean. I have one spider at the stern that kind of scares me. I leave him alone, he leaves me alone, I remove his web every morning, he makes a new one at dusk. Symbiosis or mutualism or something like that.

Here in Florida we have blind mosquitos. I left the boat for a month, and came back. I couldn't hardly see the deck at. I rinsed them off, and they produced a green slime. The next day was the same thing. It took 2 weeks for the invasion to stop.......

The mosquitoes only are a nuisance at dusk. Some well placed Muskol and a couple of cocktails and the problem goes away. Then you watch the sky and it's all worth it. Shooting stars, northern lights if you're lucky (like last night) and water so clean you can drink it.

Come on up, Ron. I'll show you a few anchorages.
