Waterbug vs. Cockroach: Fun Facts (and Bad News) About "Waterbugs"
“It’s not a roach, it’s a waterbug.” We hear it all the time. We hate to be the ones to tell you…
Quick answer: In New Jersey homes, a “waterbug” is almost always a cockroach — usually the big reddish-brown American cockroach or the shiny black Oriental cockroach, both of which love damp basements and drains. True water bugs are a different insect that lives in ponds and rarely comes inside.
