Spiders have been a plague on the earth ever since they marched their eight feet out of hell. In some areas, spiders have been known to cocoon entire trees. And it turns out there's a benefit to their efforts.

Now if we could get those spiders to do that on our fruit trees, we'd have natural pest control. This would be a good thing. Right? I think?

This happened to one of my trees. I don't think it is healthy for the tree. It was a walnut tree and only a few large branches were affected. But the leaves on those branches withered and dried up way before fall... like in early August.

I think the webs prevent the tree from getting either water, air or sunlight. Those branches definitely went to winter dormant MONTHS early.

doesn't sound like a 'plague on the earth' to me. in fact, it sounds pretty darned good.

Are they actually web-worm webs? These caterpillars are very destructive to trees. Spiders, though, no problem.

Reminds me of what happened at a state park about an hour away next to a lake. It was COVERED in spider webs almost the entire state park. It was wild looking.

It even made National Geographic.

Natural mosquito net? I am ok with that. However NIMBY.

With walnut trees are you certain it wasn't Fall webworm rather than spiders? Webworm is pretty common for walnut trees. I try to cut of the affected area and put the webworm tent in a burn barrel. The one's I cannot reach I notice the birds feeding upon.
