Because their teeth are so hard, rats are able to chew through most of the materials people use to keep them out, such as:
- Plastic
- Wood
- Brick
- Cement
- Lead
- Asbestos
- Aluminum
- Cinder blocks
- Super strong teeth are not the only superpower like trait these rodents possess. Rats can fall 50 feet without injury; they can swim and tread water for 3 days without drowning; they can squeeze through openings the size of a quarter; they breed at an astonishing rate, rapidly populating any given area; and last but not least, their genes have mutated, making them immune to most rat poisons.
