"Many crickets are attracted to areas where the moisture level is high and stable. They often move inside accidentally when a door or window is left open or sometimes in the fall when the temperature gets cooler."

As for the 2nd floor invasion, they hop - a lot - and might have gotten access that way. Or been inadvertently carried in with something, like in a box or bag that was left outside and it hitched a ride.
It was around midnight when I spotted a large black insect scurrying across the floor. I managed to capture it and with research, I learned it was a field cricket.
How did it wind up in my bedroom on the second floor? I haven't eaten in there for a long time.
Does that mean there are more?
Any additional facts/info?
Please help, thanks.
