Bagworm Treatment
What are Bagworms?
Bagworms are caterpillars that primarily feed on evergreen shrubs in Central Missouri. They construct spindle-shaped bags, measuring around 1.5-2 inches, which hang from twigs. While bagworms have a preference for juniper, arborvitae, spruce, pine, and cedar, they can also attack deciduous trees. Over the winter, the eggs of bagworms (often 300 or more) reside inside last year's female bags, serving as protective cocoons. These eggs hatch in mid- to late May, and the larvae emerge to begin their feeding frenzy.
As bagworm caterpillars feed for approximately six weeks, they progressively enlarge their bags to accommodate their growing size. When disturbed, they retreat into their bags for protection. Older larvae can strip evergreens of their needles and consume entire leaves of susceptible deciduous species, leaving behind only the larger veins. Severe infestations can lead to defoliation and, over consecutive years, can potentially result in the death of plants, especially when coupled with other stresses.
How Do I Treat Bagworms?
At Korte Tree Care, we offer various treatment methods tailored to the severity of your bagworm infestation. Here are our recommended approaches:
- Hand Picking: For minor infestations, handpicking bags during fall, winter, or early spring can be an effective control measure.
- Chemical Treatment: In cases where handpicking is not practical due to a large number of bagworms, we suggest an early June treatment. This involves a combination of Carbaryl spray and Safari drench, which targets and eradicates bagworm populations.
When you choose Korte Tree Care, you're selecting a team of professionals with extensive experience in bagworm control. Our expertise in identifying bagworms, understanding their life cycle, and implementing effective treatment methods sets us apart.
