House cricket

The house cricket (Acheta domesticus) belongs to the order Orthoptera and the family Gryllidae. While often associated with human dwellings, this species has become a significant pest in greenhouse horticulture, where stable warm environments allow them to thrive away from their natural outdoor habitats.

This pest is particularly destructive to young plant seedlings, vegetable sprouts, and decorative greenhouse crops. Being omnivorous, house crickets do not limit their diet to organic debris; they actively feed on the succulent stems, leaves, and roots of cultivated plants, often causing total destruction of small-scale sowings.

The life cycle of the house cricket includes eggs, nymphs, and adults. Females lay their eggs in moist soil or organic substrates. Under optimal conditions (temperatures between 25°C and 30°C), the development is continuous. This uninterrupted reproductive cycle allows the population to explode, leading to persistent infestations in controlled indoor environments.

Damage caused by these insects is characterized by severed stems, eaten leaf margins, and holes in the foliage. Because crickets are nocturnal and hide in crevices or under debris during the day, damage often appears overnight, leaving growers with sudden losses in plant stand density and overall crop quality.

• Implement strict sanitation practices by removing all plant debris and hiding spots.
• Use professional insecticide baits specifically formulated for cricket control.
• Install light traps to monitor and reduce the adult population numbers.
• Apply soil treatments to target nymphs and prevent successful egg hatching.
• Seal cracks and gaps in greenhouse structures to prevent entry from external areas.
