When I kept feeder crickets (because I didn't want to keep roaches, out of my NYC prejudice against them-- I'm glad I got over that, dubias are much better feeders than crickets... dubias don't smell, don't make noise) A cricket escaped and was chirping from under the couch for a month.
Feeder crickets are VERY annoying to keep and I could see escaped crickets becoming "a problem"
