What kinds of insects kill trees in the northeastern United States?
A major insect infestation can cause a tree’s health to decline to the point that it becomes liable to come crashing down in high winds, making it a major safety hazard. If you think that a tree on your property has been infested by insects, then it’ll be worth calling up an experienced arborist who can come out to conduct an inspection, and then determine the right course of action. In the event that a big tree needs to be cut down, the removal should be handled by a professional. At Mauricio’s Tree Service, our local arborists are highly experienced with tree removal in the greater Peekskill, NY area. Here’s a look at four insect species that kill trees in the northeastern U.S.
Southern pine beetles are very small—only about the size of a rice grain. However, they congregate in massive numbers and can kill expansive areas of pine forest.
The scarlet oak sawfly lays eggs on oak leaves. When the larvae hatch a few weeks later, they start eating the leaves. It’s common for the larvae to skeletonize the leaves by eating only the material between the veins. Sometimes, oak trees survive such an infestation, but this can also kill them.
This invasive European species hatches in the spring and then chows down on trees in the months afterward. These caterpillars won’t necessarily kill the tree directly, but they can weaken the tree to the point that it more easily succumbs to death from other issues.
Emerald ash borers, which are also an invasive species, lay their eggs on ash trees. When the larvae hatch, they feed heavily on the trees. While they are little beetles, they can kill swaths of big ash trees.
