WHAT IS THAT SOUND? DOES IT MEAN DANGER FOR ME?
Other insects produce sound by rubbing their legs or wings. The sound of a hissing cockroach is produced when the insect forces air through the spiracles found on their thorax and abdomen, and this sets the hissing roaches apart from other insects. Although other roach species can make a similar noise when expelling a defense odor when threatened, the hissing cockroach produces only the noise itself without other odors for defense.
