Cricket

Latin name: Gryllidae (family)

Crickets are common pests found throughout Australia, particularly in lawns, gardens, sports fields and around homes. Species such as the black field cricket (Teleogryllus commodus) are most active during the warmer months, especially after rainfall. While adult crickets primarily feed on plant material, large populations can damage turf, seedlings, vegetables and ornamental plants. They may also become a nuisance around buildings due to their loud chirping and tendency to enter homes.

Crickets are most active at night, sheltering beneath thatch, mulch, rocks and other protected areas during the day.

Lifecycle

Crickets undergo incomplete metamorphosis.

Females lay eggs in moist soil during spring and summer.
Eggs hatch into wingless nymphs that resemble small adults.
Nymphs moult several times as they grow.
Adults emerge, reproduce and continue the cycle.

Several generations may occur annually in warm climates.

Identification

Adults measure 15–30 mm long.
Black, dark brown or tan depending on species.
Long antennae and powerful hind legs for jumping.
Males produce a distinctive chirping sound by rubbing their wings together.
Active mainly at night and hide in sheltered areas during the day.

Damage

Chewed grass blades and seedlings.
Damage to vegetables, flowers and ornamental plants.
Small bare patches in lawns during heavy infestations.
Burrowing around garden beds and turf.
Nuisance noise from adult males around homes and gardens.

SOLUTIONS

In lawns, sports fields and garden beds: Apply ProForce Rumbler 1000SC to actively infested areas for effective residual control of crickets.

Around homes, patios and landscaped areas: Apply Apparent Surround to cracks, garden edges and harbourage areas where crickets shelter during the day.

Where crickets are entering buildings: Treat external perimeters, entry points and wall foundations with Temprid 75 Residual Insecticide to reduce indoor invasions.

For recurring infestations during warm weather: Reduce mulch and excess vegetation near buildings, monitor activity after rainfall and retreat with ProForce Rumbler 1000SC or Apparent Surround as required.
