How To Control Bagwormsbagworm cocoon

Have you noticed an unexplainable discoloration or browning of your trees and shrubs. There is an answer for such a thing and it is usually the cause of bagworms. Bagworms are destructive insects which attack many species of tree or bush, but are most often found on conifers like juniper, pine, arborvitae, cyprus, cedar, and spruce.

They have been coined as “bagworms” due to the insect feeds on plants and trees during the larvae stage, they wrap themselves up in cocoon-like “bags” made from twigs, leaves, and self-spun silk. Once nestled in this self-made bag, a female bagworm can lay between 500 to 1,000 eggs—meaning your bagworm problem will multiply into a major infestation if left unchecked. Each egg will hatch into another bagworm that will be ready to rip into any foliage nearby.

Once you know you have a bagworm infestation on your property, it’s best to act quickly to eliminate them. However, the tricky part about it is that bagworms are usually not noticed right away because the bags they reside in usually fool homeowners who confuse the bags with conifer cones.

How to Get Rid of Bagworms: Solutions 3 Step Process

Depending on what part of the country you are living in and the climate zone, the treatment and control approach for bagworms may change. Timing is everything when it comes to eliminating a bagworm infestation. Detecting them early will help immensely on top of using right treatment application based on the season. Whether you have a small outbreak of bagworms or are dealing with tree or shrub overrun with these pesky bugs, we recommend a simple to execute 3-step solution:

Step 1:  Handpicking- This method is best done around the fall, winter or early spring when the bagworms are in their pupae stage and have encased themselves in that self-made bag. Using any sort of chemical control will not be able to work when bagworms are in their cocoon-like stage because the encasing they are in protects them from pesticide applications. So in this case, you can manually control bagworms by simply plucking their cocoons off of the infested trees and either drop them into a bucket of soapy water or squish them.  


Step 2:  Use Insecticide Sprays - When bagworms have hatch from their bags, that is when they are susceptible to chemical treatments. We have a variety of insecticides to choose from which can kill bagworms and plenty of other problem bugs.
Demand CS Insecticide and Evergreen Pyrethrum Concentrate are just a few of our recommended products specifically for controlling bagworms.


Step 3:  Attract Bagworm Predators - If you’re wanting a more organic approach to eradicating the bagworm population on your trees and shrubs, you can make your property more welcoming to birds such as the sparrow and others. Buy a bird bath and put it on your property and lay out ample amounts of brush piles and shrubbery which sparrows can use to make nests. Sparrows will then naturally go after those bagworms for a meal and wipe them out. The con of this method may be that you may get a sparrow problem on your hands if you’re not careful.

 

Learn More About Bagworms

Bagworms are a rising pests in orchards and langscapes. They are native to North America and are common throughout the United States. Bag worms will feed on many different kinds of trees and shrubs but seem to prefer spruce and juniper.


Bagworms overwinter in last year's bags. In the spring, the eggs hatch and the small bagworms emerge and begin feeding on the tips of the foliage but a portion of the population actually shoots out stringers of silk and they baloon off to other plants. This is the method of how bagworms move around landscapes and move from one area to the next.

 

Bagworm catepillars complete their development in late August to early september. At that ttime, the male bagworm emerge from the case and mate with female produces her eggs and then drops to the ground. What follows is the bagworm eggs overwinter to complete that summer generation.

 

A female bagworm can produce between 500 to 1,000 eggs in a single bag.

 

How to Manage Bagworms

There are two approaches for controlling bagworms. One method is to physically remove the previous year's bags from the plant or tree before they have the eggs have an opportunity to hatch. To do this, all you need to do is go out and locate the bags, pull them off and deposite them into some soapy water. The reason to use soapy water is they will sink and that will kill the eggs. What you don't want to do is pull them off and drop them on the ground because those eggs will still hatch and those caterpillars will climb back up to the tree or plant and reinfest the plant.

 

The second approach is to use an insecticide. Solutions Pest & Lawn has a number of insecticides that are available that can appropriately address the situation. Most of our recommended products to deal with bagworms are reduced risk. The key to using any of these products is to apply thorough coverage. You need to make sure that you cover the area where the bagworm is feeding.

 

Bagworms are potentially serious pests whereever they appear and you should make sure to inspect plants like your juniper or spruce or other ornamentals and treat for bagworms if necessary.
