Do you know how to get rid of those cocky bagworms to secure yourself your plants and your surroundings from these uninvited guests of the season?
Read the article below to find out!

What causes bagworms?
Bagworm colonies form and increase in size mainly by spreading caused by other bagworms.
The number of eggs in a single bagworm sack ranges between 300 and 1000. The larvae hatch as tiny black dots and become giant caterpillars.
From their original nest, the larvae began to disperse at a young age by “flying” onto neighboring trees using silk threads.
The same silk and plant material from the host tree is used to make their bag. Female bagworms lay their eggs in the sack they grew up in once they become adults, and the cycle repeats.
How To Get Rid Of Bagworms In House?
Getting rid of bagworms might seem complicated, but it can be accomplished with care and consistency.
To effectively get rid of bagworms, several methods can be employed.
First, identify the infested areas and inspect plants for bagworm presence.
Once detected, manually remove the bagworms by handpicking and destroying their bags. Pruning heavily infested branches is another crucial step in eliminating bagworms.
For additional control, consider using insecticidal sprays or introducing natural predators.
If you follow these strategies on how to get rid of bagworms, you can protect your plants and prevent further damage caused by these persistent pests!
What Kills Bag Worms?
Several techniques can eliminate bagworms, both mechanical ( done by humans ) and chemical. Some of these are mentioned in the list below:
Sprays: The most straightforward method that can help you get rid of targets is the diet of bagworms.
Spraying insecticide on the areas where bagworms exist can help you eliminate these worms.
The insecticide is sprayed on the areas where the bags are during months of extensive deeding by the larvae, which reduces the chances of many larvae getting a chance to hatch.
Handpicking: Not the most efficient method, but physically removing these worms when you see them can help eliminate them in an environmentally friendly and safe way.
However, getting the job done takes much work and is time-consuming.
Pruning: Cutting off individual branches or small areas of trees where bagworms are seen can help you quickly eliminate them and stop them from spreading further.
Biological methods: Introducing natural predators and parasites can help keep bagworm populations in check.
Beneficial insects like parasitic wasps, lacewings, and certain birds feed on bagworm larvae.
You can encourage these predators by providing suitable habitats, such as birdhouses and diverse plantings that attract beneficial insects.

However, several factors should be taken into account before you make your decision.

Secondly, Bagworms primarily target evergreen trees and shrubs but can also affect deciduous plants.
If the infestation poses a significant risk to the vitality and survival of valuable or rare plant species, it may be advisable to intervene and eliminate the bagworms to preserve the health and diversity of your garden.

Prioritizing eco-friendly approaches helps maintain a balanced ecosystem in your garden.
