The following list contains examples of a variety of damaging insects.
- Aphids feed on all types of vegetation and cause serious damage to small trees and ornamental plants. The Eastern white pine is susceptible to a specie called the the white pine aphid.
- Billbugs come out of hibernation during the first warm days of spring. They vary in color from yellow to reddish-brown to black. They cause yellow irregular patches in the turf sometimes mistaken for fertilization burns.
- Chinch Bugs are one of the most destructive insects, they can reach large population levels that can kill off extensive areas of turf in a few days. Signs of a chinch bug invasion are patches of dead grass in sunny areas or where heat is radiated such as along driveways and sidewalks.
- Grubs live below ground and feed on the roots of tender grass. The best time to control grubs is in early summer, just after they hatch. Grubs can be very destructive if untreated and the damage may not show up until early fall. The Japanese beetle starts out as a white grub for about 10 months in the soil. Since grubs grow quickly, usually by late August they are almost full-sized. They can survive in almost any soil and feed on the grass roots, doing best in warm, slightly moist soil that has plenty of tender grass. Adult beetles feed enthusiastically on ornamental plant leaves.

- Leafhoppers are less than a 1/4 of an inch long and range in color from green and brown to brownish-gray. They cause white patches in the lawn and can be mistaken for drought or fungal disease.
- Mites: Several species of mites attack grasses. The Banks Grass Mite, for example, exists throughout most of the US and occasionally attacks lawns. They suck the sap out of the leaves which causes them to be blotched. This usually occurs in spring and fall.
- Sod Webworm / Moth These caterpillars chew off the grass blades close to the soil surface leaving brown stubble as damage. August is typically when we see the heaviest damage, although sometimes damage is also heavy in June.
