Black Field Cricket

Family Name

Teleogryllus commodus

Characteristics

Type:

Jumping – Non-Flying

Size:

Adult black field crickets are about 0.8 to 1.6 inches long.

Colour:

Chestnut brown or black.

Behaviour:

They have wings, although they generally do not fly. During the day, the black field cricket hides in vegetation or cracks in the soil and at night it emerges to feed above ground on decaying plant material and insect remains. They are selective feeders, preferring and killing pasture grasses, but also eating legumes, weeds and seed.

Habitats

Black field crickets live in urban areas, forests and heath. They hide in burrows and cracks in damp spots, especially in loam soils that tend to form deep cracks. When conditions are dry, crickets will burrow deep into the soil. After rain, they move to the surface. Crickets can be found beneath loose soil and stones during the day. They emerge to feed at night. Adults and nymphs behave similarly. When numbers grow large, they can often invade homes becoming a nuisance pest.

Tips for Control

Biological:
There appears to be no control of black field crickets from natural agents including diseases, parasitic insects and insects, but if adults emerge from the soil after rain during autumn, spring and summer, they are exposed to predation by birds.

Cultural:
Weedy cultivation prior to planting may encourage crickets.

Chemical:
Field crickets are controlled using insecticide-treated, cracked-grain baits.
