How to Protect Your Trees Against Bagworms 

As a homeowner, it’s essential to protect your trees from pests. Doing so will help ensure their health and longevity.  

For those who don’t know, the bagworm is one of the most destructive pests that can infest trees. These tiny insects can cause significant damage to trees if left unchecked. These pests can result in defoliation and even death.  

Fortunately, with the help of a certified arborist Fayetteville North Carolina, there are steps you can take to protect your trees from bagworms.  

Today, we will discuss what bagworms are, the signs of an infestation, and the best ways to prevent and control them. 

What are Bagworms? 

Bagworms are a type of moth larvae. They usually feed on trees and shrubs. They are called “bagworms” because they spin silken bags or cases around themselves. The bags or cases are made of silk and pieces of leaves or bark from the host plant. Because of this, you might have difficulty spotting them on your tree.  

Bagworms feed on the foliage of trees. They can lead to significant defoliation and weaken the tree over time.  

One thing to note is that an infestation of bagworms can spread quickly. That is why it’s essential to act as soon as possible when you notice them. 

Signs of Bagworm Infestation 

Unfortunately, the signs of a bagworm infestation are not always easy to spot. This is particularly true if the infestation is still in the early stage. However, one of the most noticeable signs is the appearance of spindle-shaped bags hanging from the tree branches. These bags can range in size from a few millimeters to several centimeters. This depends on the age and size of the bagworm.  

As the bagworms feed on the tree’s foliage, the leaves may become yellow, brown, or die off. During this stage, the infestation is already severe. Additionally, if you notice small holes in the bags or casings, it may indicate that the bagworms have already emerged as adult moths and flown away.  

Preventing Bagworm Infestation 

Preventing bagworm infestations is the most effective way to keep your trees healthy and beautiful. So, how do you do it? 

One of the best ways to prevent bagworms is to maintain good tree health. This means you must provide proper watering, fertilization, and pruning practices. In addition, regular inspections of your trees for signs of bagworms or other pests can help catch infestations early on before they become severe.  

If you notice any small bags or casings on the tree, remove them immediately. Make sure you dispose of them in a sealed plastic bag. This will help prevent the larvae from spreading.  

Finally, planting bagworm-resistant tree species and avoiding planting trees that are known to be susceptible to bagworms can also help prevent infestations.  


Bagworms are a significant threat to the health and beauty of your trees. That is why early detection and prevention are essential. 

Protecting your trees from bagworms requires consistent efforts and proper management practices. Doing so can help keep your trees healthy and beautiful for years.
