House crickets are nocturnal pests known for loud chirping and fabric damage. These opportunistic insects enter homes seeking warmth and food throughout the year.

What are House Crickets?

House crickets are common nocturnal pests found throughout Southern California's urban areas. While primarily an annoyance due to their persistent chirping, these insects can also damage fabrics and paper products when they enter homes in search of food and shelter.

These adaptable insects can survive year-round indoors, where they seek warm, dark spaces near food sources. Each female can lay 50-100 eggs, enabling populations to grow quickly under favorable conditions. Their omnivorous feeding habits and attraction to warm, moist environments make them particularly problematic in basements, crawl spaces, and areas near heat sources. While not as destructive as some other household pests, their presence can be a significant nuisance due to their loud chirping, especially at night, and their tendency to damage materials like paper, fabric, and even rubber.

Common Questions about House Cricket

How do I keep crickets out of my house?

Seal cracks and gaps around doors, windows, and foundations, reduce outdoor lighting that attracts them at night, and keep pantry items — including pet food — in sealed containers. Once an indoor population is established, professional treatment is usually faster and more reliable than store-bought traps.

Are crickets dangerous or just annoying?

Crickets aren't dangerous, but their chirping can be a real nuisance, and large populations can damage fabrics, paper goods, and seedlings.

Why do I have a cricket problem?

Crickets come indoors seeking food, shelter, and moisture, especially during dry spells when they're looking for relief from the heat. Improperly stored food — including pet food left out — can also attract them.
