I've only seen fireflies when I was a kid up in MN visiting the aunt/uncle at their lake cabin.
Crickets and I don't get along, especially when they are in the house and LOUD!
My strategy is to located them by ear, grab the windex bottle, and switch on the light. They'll freeze for a few seconds, then run, but usually I have a few squirts in before then. I want to leave them dead-right-there, warning to the others, but the wife insists they get dispatched.
Bugs in the sink are a gift for a blast of hot water to send them to bug nirvana.
Fun Fact:
You can "read" the temperature by counting and timing the cricket chirps.
Count for 15 seconds, add 40, get the temp in degrees F.
