Tent caterpillars and bagworms tend to start showing up in summer and keep coming until fall. Early on they will form an infestation like the one shown below. Later you will see silky encasings either across your tree or hanging in a bag. These can be a problem for your pecan trees. You can also find these worms on a number of other trees and shrubs. If you notice a large mass of caterpillars or bagworms, treat them before they have a chance to move up your tree to harder to reach places. Some options for treatment are BT, carbaryl, or Malathion. Read the label before using any pesticide to make sure your variety of tree is listed.  If you are noticing caterpillars and bagworms later on in their life cycle, you should get a hold of a tree care professional. Pressurized spray equipment is usually needed to reach high locations on the tree. Large worm bags need to be removed from the tree completely. If you are set on doing it yourself, try to remove as many bags as you can and throw them away in a sealed bag. If you can't quite remove higher bags, damage them or at least puncture them. Put a bird feeder near the base of the tree to attract birds. The birds will not kill all of the caterpillars, but they will knock down the population some.
If you are in Baton Rouge, New Orleans, or somewhere in Louisiana between, contact Big Bark Tree Care to take care of your trees.

I want to thank you this great idea! I love every bit of it. I have a bookmark you look at your new things. I have a very big pecan tree in my yard that has paper shell very large pecans on it. I him the 10 years of living here have only had pecan off the tree one time. I am in the country and had never been around bag worms tell I moved into a house with a pecan tree.We we’re so excited to have a pecan tree in our yard, but that was short lived and what I would soon find was that the bag worms were stronger than my pecan tree and that for the next 8 year we would just get angry because we didn’t know what the pesty little pecan tree killers where or how to be rid of them Last year we had pecan as most pecan tree owners did.We still had the problem of the pecans that had been on the tree in past and caused the pecans to not be any good where all over the yard were the good pecan where we still enjoyed the tree that year and decided that we were going to find away to destroy and take back our pecan tree and be rid of the nasty bag worms and that’s what leads us to where we are Leave a Reply. |
