Default Motion-activated sprinkler pest chasers

I see ads on Amazon for sprinklers which turn on briefly under

The idea seems good, but I wonder how well (if at all) they work
for things like squirrels.

Anybody got tails to tell?

Thanks for reading,

I know of a public garden that tried this at a koi pond to keep herons
and ducks away. The herons were eating young koi, and the ducks were
fouling the water. It did not work.

For squirrels that were killing two white mulberry trees in the same
garden -- eating the new shoots before the trees could get any leaves --
aluminum bands were wrapped around the trunks. Initially, the bands
were about 18 inches high; but the squirrels learned that a running leap
would allow them to clear the bands. When second 18-inch bands were
added to slightly overlap the first bands, success was achieved. I plan
to try this with my peach and loquat trees this year. I will wait until
about 2-3 weeks before the fruit is ripe.

alternative truths.
