Chewing Pests

Do you see chewed leaves or small holes on your tree’s branches? You guessed it. That’s the sign of a chewing pest.

Read on to discover exactly which chewing pest is attacking your trees.

See what looks like a large, silky spider web on your tree?

Depending on the time of year, this could be one of two pests. If you see this in the spring, tent caterpillars built it. If seen in the fall, webworms are to blame.

Tent Caterpillar Management and Treatment

Tent caterpillars are not a serious threat to your trees unless you have cherry trees.

To manage tent caterpillars, clip off the webs that contain eggs in the winter. Read more about tent caterpillars here.

Fall Webworms Management and Treatment

In addition to their silky nests, webworms can cause severe leaf damage on your trees. You have a couple of options to control and remove fall webworms. Learn all about webworms here.

You can prune off the nests and destroy them. Or, you can have Davey treat the tree with an insecticide when the insects are vulnerable.

Either way, it’s important to practice general plant heath care to help your trees fend off pests like fall webworms. Contact your arborist to develop a health care plan to improve your tree’s long-term health.

See what looks like a tear or pine-cone shaped bag on your tree?

Bagworms are most likely. If left untreated, bagworm caterpillars can strip your tree of all its foliage.

To manage bagworms, you can remove the bags by hand. Or, we can apply an insecticide treatment to control them. Get all the details about bagworms here.

See beetles on your trees or plants?

There are a few different beetles that eat tree or plant leaves.

If you see chewed leaves on your elm tree, it’s likely the elm leaf beetle. Otherwise, it’s likely the Japanese beetle.

Elm Leaf Beetle Management and Treatment

When severe, elm leaf beetles can remove all the leaves from your elm tree.

To minimize damage, apply a foliar insecticide in early summer, and if necessary, again in mid-summer. Learn more about elm leaf beetles.

Japanese Beetle Management and Treatment

Japanese beetles can destroy nearly every leaf and flower in your garden. They are always hungry.

To protect new growth on your trees and plants, have Davey apply an insecticide treatment. Click to learn more about Japanese beetles.
