Crickets are extremely common insects across the contiguous United States (and the world). Dozens of species can be found in fields, gardens, and homes, and typically pose very little threat to both humans and their environments.
A vast variety of Crickets are extremely common in most parts of the United States.
Crickets are not dangerous to humans or pets, but could be slightly impactful to gardens (depending on which plants are present).
Most cricket infestations are small in population and very easy to fix. Basic exclusion practices (or relocation) is typically all that is required.
