Cutworm Insect Control
In some areas of the country, cutworms are a notorious garden and agricultural
pest. You may or may not be surprised to learn that cutworms are not worms
at all. Rather, they are the larva stage of certain types of moths. Cutworm
larvae are from a subset of the Noctuidae Moth, a large family of moths.
The Cutworm gets its name, as they often feed on plant stems, cutting the
seedling or plant down, by eating away the stem at or near the base.
Cutworms are nighttime feeders. During the day, they hide in garden litter
or under the soil.
These pests are sometimes called Tomato Cutworms, as they can be a real problem
with tomato plants.
Identification / Description of Cutworms:

an inch long. They are brown, green, gray, or yellow in color. Some but not
all, have longitudinal stripes.
Cutworm Feeding Habit.
Cutworms emerge to feed on plants at night. They eat the stem, leaves, and
buds. They feed on the first part of the plant they encounter....the stem.
Sometimes, they will eat the entire plant. Other times, they cut the plant
down as they eat, consuming some of it, before moving on to graze on other
Late in the season, cutworms can chew holes into the fruit of tomatoes, peppers

The larvae or pupae over winter in the soil or even a mulch pile. Winter
plowing or roto-tilling can kill them.
Plant collars - Create a barrier around your plants. Use cardboard, aluminum,
plastic bottles, milk jugs or plastic cups. Place them around the plant,
a couple inches deep into the soil, and 3-4 inches tall above the soil.
Home gardeners should roto-till the soil as soon as the ground can be worked,
to expose and kill dormant larvae.
Manually kill any cutworms you see.
Minimize compost piles and garden mulch, as these are places they hide during
Keep weeds down in and around your garden, to "starve them out".
