Insect & Disease Control

The control of harmful pests is an significant part of tree care, and some pests may require immediate attention. Gypsy moth, for example, can completely defoliate a tree in one season! At Carroll Tree, we can identify problems, and if treatment is necessary, determine the best method of control.

Harmful insects are commonly found on, under, or inside of leaves, twigs or bark. Obvious signs include chewed or damaged leaves, leaves with tunnels or mines, and holes in the bark of the tree. However, depending on the insect, it can be difficult for some homeowners to see activity. Some tree diseases may cause death immediately and others can ruin a tree's aesthetic appeal or weaken it to a point where the tree becomes vulnerable to environmental stresses.

In general, timing is critical for treatments to be effective because all insects have unique life cycles!

If you have a tree that does not look well, if you notice unusual insects, or if you just have a tree that is especially important to you, it may be appropriate for an arborist to give an assessment of your tree’s health.
