Our professional arborists can determine what the insects infesting your plants are. Once the insect is identified, it can be determined if it is harmful to the tree, beneficial to the tree, or has no effect. Some insects can be beneficial, by controlling populations of harmful insects and it’s in your best interests to keep them. If the insects are harmful, we then see how harmful they are, and if it is worth treating. Most professional arborists operate on the philosophy of treating only when the environmental and economic risk from the insect has reached a certain threshold.
