House crickets, as the name implies, are found inside homes and present a problem due to their incessant chirping which can easily become overwhelming. In addition, they are known to eat many substances such as paper and fabric which can damage property if left unchecked.
Field crickets are found in lawns and gardens and present their own unique set of challenges for a homeowner. They can also invade houses and cause a nuisance. The main threat crickets pose is the fact that they feed on soft parts of plants, including grasses and any plants you might have in a garden. This can cause both aesthetic and structural damage to the plants, and any cricket problem should be dealt with quickly.
