Protect Your Trees From Damaging Insects

Michigan is well known for its forests and wide variety of trees. As part of our landscapes, trees are the centerpieces. They not only add beauty and shade but they provide enjoyment for generations to come if they are cared for properly. Unfortunately, there are a host of tiny insects that can fell even the mightiest of oaks. 


In large numbers, insects can cause a lot of damage to your trees and in some cases, even kill them. It is vital as a homeowner to be on the lookout for any damage on your trees that are caused by pests. Only with early detection can you limit the damage done to your trees. Tent caterpillar

Tent Caterpillars

Everyone has seen those silk webs in the tops of trees. Sometimes trees can be completely covered in them. These are the webs of tent caterpillars. These aggressive caterpillars have an insatiable appetite for leaves and if there are enough of them, they can severely damage a tree and affect its growth. You can simply prune away the affected branches if they are within reach. For higher branches, call a professional arborist. No matter how tempting it may be, do not use fire to burn tent caterpillars. It will kill the branch and affect its growth.

Gypsy Moths

Gypst moths are the locusts of lower Michigan. The caterpillars can strip a tree of it’s foliage, making it vulnerable to pests and the diseases they carry. The gypsy moth population was brought under control in the 90s by the introduction of a fungus but in recent years the dry springs have prevented the fungus from spreading, giving gypsy moths a chance to make a comeback.Carpenter ants

Carpenter Ants

Carpenter ants, as their name suggests, love wood. They usually make their homes in trees and dead logs. Contrary to popular belief, carpenter ants do not eat wood. Instead they remove wood as they carve tunnels and galleries for their nests. Their primary food sources are living and dead insects. As they tunnel through dead parts of the tree they can damage wood that is already weak soft which can compromise the strength of large branches. Carpenter ants can be treated with simple pesticides applied to the base of the tree.

Emerald Ash Borer

The emerald ash borer has been Michigan’s public enemy number one for many years. First noticed in 2002, this invasive species is responsible for the deaths of over 30 million ash trees in southwestern Michigan and has decimated the ash population in The United States. This is why the USDA has issued rules that ban the transportation of firewood across state lines.

Asian Longhorned Beetle

Asian longhorned beetles are a new threat in Michigan. They do not discriminate when it comes to feeding on trees. Adults are mostly active in later summer to early fall when they start to drill through trees to create chambers. Over the course of several years, the damage can become too much for the tree and it will defoliate and die. Asian longhorned beetles do not move long distances and are spread by the transport of firewood. The only sure-fire way to prevent these invasive pests from killing more trees is to remove infected trees and destroy the wood as soon as possible.
