Cockroaches show complex behaviors and nociceptive responses that raise important questions about insect welfare and our treatment of pest species.
While scientific consensus on cockroach sentience remains uncertain, cockroaches display behaviors consistent with nociception and aversive experience. They can learn to avoid harmful stimuli and show protective responses to injury. Given the billions of cockroaches killed through pest control annually, even a small probability of sentience has significant welfare implications. More humane pest management approaches deserve consideration.
