Book 25, Question 85
Why do rats live near people, and how can we keep them away?
Rats live where there is food, water, and shelter, and people often provide all three by accident.
Open trash, spilled food, and clutter give them homes. Rats are very smart and good at climbing and squeezing through small holes. The best way to discourage them is to keep trash sealed, clean up food, and close up gaps in buildings.
