The attached photos are of an insect found in my basement in Bel Air. Prior to attempting to identify it I released it. It appears to be a katydid from the Pacific coast. Can you confirm the identification? Is there any concern about it appearing here?
This looks like camel crickets. They are widespread in the US. They get their name because of their humpbacked appearance. These crickets are attracted to damp, dark locations in the home, usually in the basement the garage or garden shed.
Exclude them as you would other nuisance pests by sealing up openings around foundations, doors, and windows. Dehumidify damp basements and fix any leaks to eliminate moisture. Remove hiding places such as wood piles, mulch, and groundcovers from next to the foundation of the house.
