I have a tall (20-25 feet) cedar hedge that is infested with spider
mites. Given the height of the trees, I cannot easily spray them with
insecticide. As an alternative, I was thinking of blasting away the
mites with a power washer. If done on a regular basis, the mites may
be reduced in number sufficiently for the trees to survive their
attacks. I was thinking of purchasing a 1700psi electric washer for
this purpose. Makes sense ?

Or use a systemic insecticide that is taken up by the tree so when the
insects feed they do themselves in.

You might kill the hedges with pressure. It fires water into areas
that don't get water which can lead to rot.
Try it with a hose. Look for non-poison repellants also. (there might
be other plants, put nearby, that repel the mites. I've planted garlic
along with other vegetables that kept some bug attacks down. you're
repellant will vary.)
No, it'd damage the hedge. Spider mites are sometimes very difficult
to get rid of even in house plants.
Try a little more finesse.
Rather than going to the toxic chemicals right away, use a hose-end sprayer
and heavily spray the hedge with water mixed with a tablespoon of liquid
dish soap per quart (liter). Use Safer's soap (or equivalent soap-based
insecticide) if that doesn't do it.
On house plants, the recommendation is to spray/wipe them with rubbing
alcohol. But that'd be more than a bit dangerous and expensive on a
