Why do crickets chirp?

Ehrlich Answers

"I’ve been hearing loads of crickets recently; why do crickets chirp, and how do crickets make noise?"

The familiar cricket noise you hear on summer nights is made by male crickets. They produce this sound by rubbing their wings together, a process called stridulation. One wing has a set of ridges, almost like a comb, and the other has a hardened edge that works like a scraper. When crickets move their wings back and forth, this action creates the distinctive cricket chirp.

Males chirp mainly to attract females, though they may also use the noise to warn other males. Temperature can affect the rate of chirping, which is why cricket noises at night may seem faster or slower depending on how warm it is.

While the sound of crickets outside may be a normal part of summer evenings, finding them indoors is less than ideal. Besides the constant cricket sounds, some species may damage fabrics, paper, or stored items if infestations grow. Our cricket control technicians can inspect your home, help remove existing crickets, determine how crickets are getting inside, and recommend treatments to reduce activity.
