Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "паразиты" (parasites) which is narrower. "Vermin" is broader, including rats, mice, cockroaches. The Russian "вредители" is closer in agricultural context but less common for household pests. The human metaphor carries the same extreme offensiveness as "паразиты" when used politically.
Common Mistakes
- Using it as a countable noun (*a vermin). It is uncountable/collective. Incorrect: 'I saw a vermin.' Correct: 'I saw some vermin' or 'The place is full of vermin.'
