Common Pests
Aphids
Aphids, also known as plant lice, they are small sap-sucking insects. The damage they do to plants has made them enemies of farmers and gardeners the world over. Read More
Japanese Beetles
These insects damage plants by skeletonizing the foliage, that is, consuming only the leaf material between the veins, and may also feed on fruit on the plants if present. They can be recognized by their iridescent copper-colored elytra and green thorax and head. Read More
Bag Worms
Bag worms are caterpillars that make distinctive spindle-shaped bags on a variety of trees and shrubs. Read More
Zimmerman Pine Moth
A pest of pines in the Midwest but has become increasingly noticeable in the past few years. The larva of this moth species is a borer that attacks pine tree trunks and lateral branches. Trees rarely are killed by this insect but they are disfigured as branches die. Borer damage can weaken trees and cause trunks or branches to break off during heavy ice, snow or wind. Read More
Magnolia Scale
one of the largest and most conspicuous scale insects known to occur in Ohio. Adult females may reach nearly 1/2-inch in diameter when fully grown. The scale is shiny tan-brown and smooth. As the scales grow, they are often covered with a white mealy wax. This wax is lost at the time that the crawlers emerge. Read More
Tent Caterpillar
Populations fluctuate from year to year, with outbreaks occurring every several years. Defoliation of trees, building of unsightly silken nests in trees, and wandering caterpillars crawling over plants, walkways, and roads cause this insect to be a pest in the late spring and early summer.

Cottony Maple Scale
A highly modified insect pest that commonly attacks silver and red maples. The scales are usually first noticed when the females produce an egg sac which appears as a 1/4 to 1/2-inch long ball of cotton. Heavy infestations can result in branches being turned completely white with the egg sacs. Read More
European Pine Sawfly
The most common sawfly found infesting pines in landscapes, ornamental nurseries and Christmas tree plantations. Sawfly larvae look like caterpillars but they are the larvae of primitive wasp-like insects. They are common from southwestern Ontario through New England and west to Iowa. Read More
