How to get rid of little green worms hanging from trees?

These little lime green worms hang down from silken threads. They are eating the leaves on my ash trees. What are they? How do I get rid of them?

Answers:
You're not gonna like this...but it really works for these and other creepies like tent worms, army worms and cabbage worms. First of all you need to go to a garage sale and find a blender. You'll get killed if you use the one in the kitchen for this. Collect a cup of the critters from your tree when they clump up in the tree for overnight warmth. Dump them in the blender and add 2 cups of water. Turn it to "puree" and leave it run for about 30 seconds. The water will turn green. Strain the resulting liquid through a coffee filter into a jar with a tight fitting lid. You'll get about 2 cups of this delightful cocktail. It can be frozen for up to 6 months without any loss of potency. Mix at a ratio of 10 parts water to 1 part concentrate. Add a couple of drops of dish soap to make it stick to the leaves better. This can now be put in a sprayer and the afflicted plant sprayed. Aim at the leaves that are being eaten. Kills the worms dead and it won't hurt anything else! Why does this work? Well, apparently they are not immune to their own gasto-intestinal gut bacteria and it is poisonous to them.
