White oak trees are large, beautiful trees that feature light gray knotted bark and leaves that shift from pink to deep green to red depending on the season. Keeping your white oak tree beautiful and healthy involves some maintenance. That maintenance includes monitoring the white oak for signs of insect infestation and calling in a tree care service or pest control company to help deal with the problem with as little damage as possible to your tree.
Here are a few of the insects that can infest and damage a white oak tree – and the symptoms you need to watch out for.
Two-Lined Chestnut Borer
The two-lined borer gets its name from the stripes on the bodies of adults and the boring through done by larvae that feed on the bark material. Symptoms of a two-lined chestnut borer infestation include scattered wilting and dieback of leaves throughout the tree. There can also be dust on the bark around where the larvae are boring tunnels through the tree. Left untreated, the borers can kill off enough of the heartwood that the tree will die.
Call in a tree care service, like A-1 Expert Tree Service, to confront the borer problem early in the infestation. The service can trim away already affected leaves, monitor the tree’s general health and improve where necessary, and possibly apply chemical controls to eliminate the borer problem.
Kermes scale infestations can be easy to overlook due to the fact that the adult insects have rounded, bark-colored bodies that make the insects resemble buds on the tree. If the infestation becomes severe, the tips of affected branches will darken, droop, and then fall off of the tree.
While the scale rarely does any serious damage to the tree, the cosmetic damage alone can be bothersome. Call in a tree care service as soon as you suspect a scale infestation or if you simply notice some unusual buds forming. The tree care service can apply chemical controls including crawler sprays, which treat the adults, or dormant oils, which treat the larvae during the off-season.
Oak Leaf Skeletonizers
Oak leaf skeletonizers are a type of moth that gets the name from the fact that larvae feeding on the tree will eat away at the underside of the leaf until only the veins or skeleton of the leaf remains behind. The affected leaf will simultaneously dry out and will eventually fall from the tree prematurely. Eventually, large sections of the tree’s leaves can go missing due to these moths.
If you start to see signs of skeletal leaves, call in a tree care service to apply chemical controls to get rid of the problem before the damage progresses.
