Why crickets cluster where they do
Camel crickets (the humpbacked, jumping kind) are drawn to damp, dark spaces — basements, crawlspaces, and garages are their favorite spots in Hampton Roads homes. Field and house crickets are more drawn to light and warmth, which is why they often end up indoors as temperatures drop outside.
Neither type bites people, but large populations can damage fabric, paper, and cardboard stored in basements, and a persistent chirping problem is enough to disrupt anyone's sleep.
Crickets are also a food source for other pests, including spiders — so a cricket problem can indirectly contribute to more spider activity too.
What actually reduces cricket activity
- Reducing moisture in basements and crawlspaces — crickets need damp conditions to thrive
- Sealing foundation gaps and basement window wells, common entry points
- Exterior perimeter treatment to reduce populations before they move inside
- Removing clutter (cardboard, stacked paper) that gives crickets cover

Cricket control questions
Crickets don't bite people. In large numbers, though, they can chew through fabric, cardboard, and paper products, particularly in basements and storage areas.
Basements offer the damp, dark conditions camel crickets prefer. A large population usually points to excess moisture or an easy entry point that needs to be addressed.
Yes — crickets are a food source for spiders and some other insects, so reducing cricket activity often reduces spider activity as well.
Exterior treatment combined with sealing entry points and addressing moisture issues is the most effective long-term approach — treatment alone without addressing the source tends to be temporary.
