Bagworms, also known as evergreen bagworms, are larvae that turn into black-colored moths. Male bagworms have a dark brown body, while the women bagworms have a yellow-colored tone and look like maggots.

Bagworms are one inch long that hang on the trees. When a bagworm hatch from its eggs, it covers itself with leaves, making a cocoon called a bag. It holds the bag by its legs and silk that the larvae produce itself.

The bags protect themselves from predators like birds and other insects. These bags can blend with the color of the tree and make it impossible to spot them through human eyes.

An adult bagworm has wings and eyes, while the female bagworms don’t lack eyes and wings. A male adult moth has the freedom to leave its cocoons while the women have to live inside their cocoons, lay eggs and die.

Along with the safety precautions, the usage mentioned on the labels must be followed. Excess pesticides can damage your plant and contaminate the soil, ponds, or water sources nearby.
