You certainly wouldn’t like my “Free Swimming Lessons for Chipmunks” plan in effect at the BraveMan abode . . .
Is that the bucket pool and sunflower seed lesson?
That’s a mean one because the animal struggles to exhaustion before drowning. Drowning is quick, but being left in water with no rest and no escape is a toughy. Maybe it beats being eaten alive by a raccoon, but it’s slower. Not sure...
Can’t you just use a trap that kills them outright?
BTW, if you’re annoyed enough with them to eliminate them, I have plenty of sympathy for you about all the damage they’ve done to your environs.
