Below are the most common insects that afflict landscapes. Our research will give you the knowledge to diagnose issues and also offer you solutions with our customized Tree and Shrub services.
Large populations cause curling, yellowing, and distortion of leaves and stunting of shoots; they can also produce large quantities of a sticky substance known as honeydew.
Weevil damage shows up on the foliage in crescent ?C? shaped feeding patterns. After hatching, weevils are legless grubs that feed on the roots of the plant.
When a birch is severely infested, holes where the borers have entered the tree are visible on shadier portions of the tree. Early stages of birch borer usually reveal early browning of foliage and leaf drop.
Ends of the branches will have downward curled tips on the new growth. Previous damage resembles dried cones on the ends of branches that curl downward.
These sociable caterpillars live together in silk nests, which they build in the heart of cherry and apple trees.
Symptoms of emerald ash borer don't become obvious until two or more years after borers enter a tree. D-shaped exit holes, just 1/8" in diameter, mark the emergence of adults. Split bark and foliage dieback may also indicate pest trouble.
The fall webworm builds impressive silk tents that sometimes enclose entire branches. The tents appear in late summer or fall - hence the name fall webworm.
Beetle damage looks like little holes all over the leaves. This damage typically arrives in late June when the grubs turn to their adult form of beetles. These beetles can sometimes defoliate a tree in 3-4 days.
If your plant leaves look like someone was doodling squiggly lines, you have leaf miners. If you look closely, you can often see a dark dot at the end of one of the lines. That's the culprit at work.
When leaves from maple trees suddenly drop to the ground in late May or early June, you may be seeing maple petiole borer damage. The stems of the leaves are often black while the leaves are still green.
Early warning signs of this pest infestation in a maple will be premature yellowing of the leaves leading to early leaf drop. Find out how to identify this pest.
Galls are formed by insect/mite feeding or egg-laying activity. Learn more about mite gail and what you can do about it.
Sawflies resemble caterpillars and feed in groups on needles and foliage making them weak and susceptible to other insect and disease problems
Scale insects look like little bumps along the stems of plants and are often mistaken for some type of disease. They adhere themselves to the plant and suck on the plant's juices, drying it out and causing serious damage.
Vegetation such as hostas and some flowers will have large gaping holes in them as a result of slugs and snails feeding.

The larva of this moth species is a borer that attacks pine tree trunks and lateral branches. Typically there will be large collections of sap along the first 10 feet of the tree.
