In fact, some go as far as 100,000Hz and moths reach an astonishing 240,000Hz. As far as safety goes, human cochlea prevents us from hearing such frequencies; it is a physical limitation that has nothing to do with ear training. It varies from a human being to the next, but most of us cannot hear anything beyond the 20,000Hz. So which are the effects on the human ear of ultrasonic pest control? Virtually none because we cannot hear it.
