Cabbage Worm

There are several types of cabbage worms, but the two species that are the most common and damaging to the garden here in Ohio are the Cabbage White butterfly (Pieris rapae) and the Cabbage Looper (Trichoplusia ni).

Host plants include broccoli, cauliflower, Brussels sprouts, collards, kale, mustard greens, turnip greens, radishes, turnips, rutabagas, and kohlrabi.

Larvae will feed on the leaves of plants, leaving behind irregular holes. As they grow, they can bore into the center of the plant, contaminating them with fecal pellets.

Natural predators include parasitic wasps, spiders, green lacewing, and insect-eating birds.

We recommend using Bonide BT Thuricide Spray RTU if you have an infestation.
