How to Identify It
Dark brown to black, rounded body, long antennae, and powerful hind legs for jumping. Males chirp by rubbing their wings together, usually at night.
Size: 16–25 mm
Commonly Confused With
Cave crickets (see below — humpbacked, silent, no wings) and grasshoppers (found in open fields, not typically indoors).
Why It Shows Up
Cooling fall temperatures push them toward structures for warmth, and they enter through foundation gaps, door thresholds, and garage doors, drawn to outdoor lighting near entry points.
Where Homeowners Find It
Basements, garages, and crawlspaces, often near foundation cracks and door gaps; occasionally in closets where they can damage stored wool or cotton clothing.
Seasonal Activity in KC
Peak indoor activity September through November as temperatures drop.
Risk Level
Primarily a noise nuisance; large numbers can occasionally damage fabric, but there's no health or structural risk.
What You Can Do Yourself
- • Seal foundation gaps and install door sweeps, especially at garage doors.
- • Reduce exterior lighting near entry points or switch to yellow LED bulbs.
- • Remove leaf litter and debris piles close to the foundation.
What Professional Treatment Involves
Exterior perimeter treatment timed ahead of the fall migration, focused on foundation gaps and entry points, resolves most indoor cricket activity.
