What is this spider web looking stuff? It is killing this tree? What would I spray these trees with to kill this stuff?

Pryker, Your first pic is of a oak leaf gall, this is caused by one of many small insects, flies, or wasp that lay eggs in the tissue of the leaf causing a protective gall to form, no worries, it won't hurt the mighty oak. The second pic is of a webworm, which can be controlled with a number of insecticides, but unless there is a large population they won't cause long term damage.

Webworms, heck, pecan trees. Get you one of those extended reach propane tourches and burn the bas ......................... tards off.

The owner of the second tree told me he though it was something called bagworms. I looked it up and bag worms form those little carcas looking bags and I did not see any of them.

What do you mean by "Heck, Pecan Trees"?

Thanks for the help!!

I've heard that you are supposed to cut down the bagworms and burn them, I would be cautious if you burn them right in the tree. Hope that helps.

For tent insects I prune out the tents, then 2oz / gal dish soap over the tree. GREAT control.

There is a biological control called btk. We use it on tent caterpilliars up here. Maybe that would work.

fall webworm or uglynesters. They don't harm the tree, the foliage is goingto drop off any way. Any contact pesticide will do them in.

The best strategy is to prune out the webs in the daytime. During the day eastern tent caterpillars (spring) and fall webworm are in the web for protection from birds, so a simple pruning gets then all. If using any insecticide, you must make sure to penetrate web with your spray, in order to contact the caterpillars, or your application can be wasted. But then if you just spray, the ugly web remains - so pruning is still the best.

It is a common error for the uninformed to call eastern tents and fall webworms as "bagworms", but bagworms are a totally different animal.

Tent Catapiller without a doubt. Can prune out tents and/or treat with Sevin, Orthene, BT......any of these will take care of them.
