Common Entry Points Rats Use to Enter Homes and How to Seal Them
By Pure Pest -
Introduction
Rats are among the most persistent household pests affecting homes across Chandigarh, Mohali, Panchkula, Zirakpur, and other cities in Punjab. While many homeowners focus on removing rodents after an infestation occurs, preventing rats from entering the property in the first place is often the most effective long-term solution.
One of the reasons rats are difficult to control is their ability to squeeze through surprisingly small openings. Even a small gap in a wall, pipe opening, roof vent, or drainage system can provide easy access to your home. Once inside, rats can contaminate food, damage furniture, chew electrical wiring, destroy insulation, and create serious hygiene concerns.
Understanding where rats enter and how to properly seal those entry points is essential for maintaining a rodent-free home. This guide explains the most common entry points rats use and provides practical tips for sealing them effectively.
