Ha, sure, let them fire up those carbon monoxide generators in tunnels with poor ventilation. That will save the IDF a lot of work.
Yep. I remember when I was a kid and rats had tunneled under the chicken coop. Blocked all visible hole except for one. Dad would take them out with a .22 as a few tried desperately to escape. He shot maybe 3. The rest must have croaked from CO poisoning because we never saw any indication of them again
