Field Cockroaches

Facts, Identification, & Control

Scientific Name

Blattella vaga

Appearance

What Do They Look Like?

  • Color: The field cockroach looks similar to the very common German cockroach, grayish to olive-brown with two brown to black stripes on the top of its head.
  • Size: About 1/2 inch long.
  • Identification: To make a personal identification, look at the face of the field cockroach. If you can see black stripes between the eyes, it is a field cockroach because German cockroaches do not possess these stripes.

How Did I Get Field Cockroaches?

Field cockroaches thrive in leaf litter and piles of cut grass outdoors. However, during especially warm and dry weather, the pests may enter homes. Some homeowners will incorrectly think they have German cockroaches invading their home, when it actually is the field cockroach. Some common entry points include:

  • Gaps beneath doors
  • Holes around the foundation
  • Poorly sealed windows

How Serious Are Field Cockroaches?

While they are not as widespread as other species, field cockroaches cause similar concerns. The insects hide in cracks and corners in houses, though light sources may attract them, unlike the German cockroach’s response of avoiding light. A field cockroach also spreads bacteria, which can result in food poisoning when the pests get into pantries. Populations of this fast-breeding insect increase rapidly if left unchecked.

Signs of Infestation

Seeing field cockroaches either inside or outside is the most obvious sign of an infestation.

Behavior, Diet, & Habits

Unlike many other cockroach species, field cockroach adults do not shy away from light and are active during the day and may also be attracted to lights in and around homes at night.

Where Do They Live?
Originally from Asia, Blattella vaga has been introduced into the Southwestern United States, including Texas, New Mexico, Arizona, and parts of southern California. Within this region, field cockroaches are most common in irrigated areas. Leaf litter and other types of outdoor plant debris are their preferred habitats.

Life Cycle
Field cockroaches go through three developmental stages eggs, nymphs, and adults. Adult field cockroach females carry their eggs in specialized cases, with each egg case generally containing from 30 to 40 eggs. Field cockroaches complete a life cycle in about 90 days.
