How Small a Hole Can Rats Get in?

There are a number of ways rats can get inside your home, from cracks in bricks to holes in water pipes. Rats have very good climbing skills and can squeeze through very small holes. In fact, they can even hold their breath for 30 minutes! This means that you should take steps to keep your house rat-proof, including repairing cracked or loose bricks.

Rats can fit through holes about the size of a dime. The size of the hole that they can squeeze through depends on the shape, height, substrate, and grip. It also depends on the age of the rat. Juvenile rats can fit through much smaller holes than adult rats.

If you have an adult rat, you can expect him to fit through a hole as small as a quarter. Rats are known for their agility and flexibility, and they can squeeze through a hole as small as 0.705 inches wide. But you should keep in mind that some larger rats are not able to squeeze through the hole as easily as their smaller cousins.

Rats can fit through very small holes thanks to their cylindrical shape. Their long hairs and whiskers help them measure if a hole is big enough for them to squeeze through. Because they spend most of their lives in tight spaces, they are particularly adapted to squeeze through small gaps.
