- Color: Typically black but can be brown or straw-colored.
- Size: 1/2 to 1 1/8 inch long.
- Stout body with large “jumping” hind legs characteristic of crickets.
- Slender antennae much longer than the body.
- Wings on adults lay flat on the back and are bent down on the sides.
- Adult females have a long slender, tube-like structure (ovipositor) projecting from their abdomen which they use to lay eggs.
- Nymphs look like adults but are smaller, and the wings are not fully developed.
Field Cricket Habits:
- Typically overwinter as eggs that have been laid in moist, firm soil or occasionally as nymphs.
- Females lay 150-400 eggs which hatch in the spring.
- Developmental time (egg to adult): about 78-90 days.
- There can be several generations per year.
- They are unable to survive indoors for long periods and usually die off by winter.
- They are active at night and hide in dark warm places during the day.
- They are attracted to lights, often by the thousands.
Damage Caused by Field Crickets:
- As agricultural pests as well as household problems in late summer when they move out of fields and into buildings.
- May chew furniture, rugs, and clothing.
- Chirping of adult males is irritating to some individuals.
- Moist harborages, e.g. wood piles, landscape timbers, stones, rocks, etc.
- Droppings which look like large pieces of pepper.
- Damage to materials inside the home.
How to Control and Kill Field Crickets:
- Moist harborages, such as wood piles, landscape timbers, stones, rocks, etc., should be removed.
- The yard should be frequently mowed, weeds should be kept to a minimum, and flower beds should not be over mulched.
- Entry into buildings should be prevented by sealing and caulking gaps around siding, windows, doors, pipes, wires, etc.
- Yellow bug-lights or sodium vapor lighting should be used outside to avoid attracting crickets to doors or windows.
- A vacuum should be used to remove accessible crickets.
