How 'well separated' need they be? I've created three veg beds for rotation
purposes, about 3 or 4 feet apart. Will this not work? I thought it was
about nutrients in the soil getting exhausted as much as (or more than) an
insect problem.

Depending on the pest, anywhere from 20' up to several miles.

Rotating crops does no harm, and the nutrient aspect is real. It is
more about not growing crops with too much nitrogen than it is about
anything getting exhausted, though. However, unless you use large
quantities of animal manure, it isn't a major issue.
