When we think of a rat residence, we may immediately conjure up an image of a dark, damp sewer or abandoned building. However, there are many other synonyms for this term that describe where rats may inhabit. They include dens, burrows, nests, lairs, tunnels, warrens, and even rat holes. These rodents may also make their homes in bushes, trees, or piles of debris outside. It's essential to identify these rat residences to properly remove these pests and prevent them from returning. Taking preventative measures such as sealing gaps in walls, securing trash bins, and keeping food stored properly can also discourage rats from making themselves at home.
