Bug eating cedar fence

Asked September 23, 2019, 9:32 PM EDT

Hi, There is a bug infestation in my cedar fence. From looking at pictures, it looks like the Japanese longhorn beetle. Is there a way to save our fence? They don't look to be eating the pressure treated wood but the pictures of the cedar gate are attached. The same pattern of destruction happened to a walnut tree and dogwood tree nearby. We had both trees taken down when they died. We have a pear tree near the fence gate. It doesn't look like the bugs got it yet, is there a way we can keep the bugs away from the pear tree? Thanks

Hi - This looks like it could be damage from paper wasps. They scrape the outer surface of wood for material to build their nest. Here is information about paper wasps and what you can do if you find a nest nearby. https://extension.umd.edu/hgic/paper-wasps Resealing or painting the wood will help to deter insects from causing damage.

Insects you find on dogwood, walnut, and pear trees are likely something else. We would need to see photos of plant symptoms or the insects in order to diagnose what you have and to make recommendations. If you are growing the pear tree for fruit, there is information here on our website about the pests of pears and what you would need to do to manage them. https://extension.umd.edu/hgic/topics/apple-pear-insects
