Etymology
The word 'infestation' originates from the Latin verb infestare, meaning "to attack, disturb, or molest." This verb itself is derived from the adjective infestus, signifying "hostile, unsafe, or dangerous." The core root fest- is thought to be related to the concept of striking or aggression, linking back to Proto-Indo-European roots associated with hostility. Over time, the meaning evolved from a general sense of hostile invasion to the specific modern sense of being overrun by troublesome pests or parasites, capturing the process and state of such an unwelcome incursion.
