What are some common pests that can harm my trees?

Aphids

Typically found on the underside of leaves, Aphids eat sap in tree leaves which leads to stunted leaf growth or can cause them to curl up and then turn yellow. 

Gypsy (or spongy) moth 

Gypsy moth caterpillars munch on more than 300 species of evergreen and deciduous trees. Usually every 10 years, their population explodes causing harm to many trees in Wisconsin. 

Asian longhorned beetle

As lovers of maple, Asian long-horned beetles often infest trees during the summer months by laying their eggs on the tree then as they grow, they will burrow deeper into the wood of the tree. The tunneling often causes harm to trees which is why the Asian longhorned beetle is on the DNR’s invasive species list.

Emerald ash borer

This invasive beetle was first detected in Wisconsin in 2008 and is similar to Asian long-horned beetles where they often burrow into trees. The larvae cause harm to the trees by feeding on the wood underneath the bark. 

Squirrels and other small animals

While they’re cute to look at, squirrels, rabbits and porcupines can cause some serious wounds to trees and ultimately cause them to die. These animals feed on small tender twigs, newly developed leaves and tree roots.
