In this month’s blog we are discussing the pests who invade and destroy our trees. We will discuss what you can do to identify and protect your landscape from potentially being destroying by these invaders, and when to contact an arborist for help. “Invasive pests and diseases are the biggest threats facing Indiana's urban and rural forests today.” (Purdue Extension). Therefore, it is important to identify and stop these intruders before they take out our beautiful trees and forests.

So what pests are we talking about? “There are hundreds of pests and diseases killing millions of trees across the country.” These are a few common pests overtaking trees: (Arbordayblog.org)

· Asian Longhorned Beetle

· Emerald Ash Borer

· Pine Beetle

How do these pests get here and why are they are problem? “Many invasive forest pests reach our shores hidden in shipments from other countries. Our native tree species have never seen these pests before and therefore have no defenses against them. When invasive pests arrive on our shores, they have left behind the natural factors that keep their populations in check, and their populations can grow out of control.” (Purdue Extension)

How do you check your trees for signs of an infestation? First, make sure you know what type of trees you have. If you know the species of trees, you can then check with the corresponding pest known to attack that species. “Signs of pests will vary from tree to tree and the type of infestation. One of the first visible signs of pests will show on the leaves. Symptoms of an infestation are also visible on bark, branches and twigs.” (Arbordayblog.org)

When should I check for signs of tree damage? “The end of the summer is a great time to check trees for pests and disease. August is tree check month, an annual campaign to check for the Asian Longhorned beetle (ALB), however it’s also a fitting time to check for other pests. Spending 10 minutes of your day to check trees for signs of damage can help save your trees, and your wallet.” (Arbordayblog.org)

If it’s too late and you find your trees are already damaged, contact a certified arborist for assistance with tree removal and pest containment.
