How to catch a flea off a villager?

Excuse me, but could you elaborate on your question? I'm a professional in cryptocurrency and finance, and I'm not sure how catching a flea off a villager relates to my area of expertise. However, if I were to take a guess at a general answer to this question, I would suggest that it might involve using a fine-toothed comb or a flea trap, being gentle with the villager to avoid causing them discomfort, and perhaps consulting with a veterinarian or pest control professional for the most effective and humane methods. Is there a specific context or scenario in which you're asking about this, or are you simply curious about the general process?
