interlopers
Trespassers on territory
Interlopers are people who intrude where they don't belong or aren't wanted.
The word suggests unauthorized presence—someone inserting themselves into a situation, place, or group without invitation: The old-timers viewed the newcomers as interlopers.
In business, an interloper may be a competitor encroaching on established territory.
