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
Vegetation such as hostas and some flowers will have large gaping holes in them as
a result of slugs and snails feeding.

plain piece of paper and these instructions.
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.
