Rat interesting facts are numerous. They are one of the most hunted, feared and dangerous rodents in North America. As a result there has been a lot of research completed with regard to rats. This section highlights some of the more interesting facts about the rats that live in North America.
- Rats are exceptionally apprehensive of new things they may find in a well traveled pathway (this makes trapping a more difficult task).
- Rats won’t let a small barrier like a doorway stop them from getting into a building. They will take whatever route is best:
They have been known to run along or climb electrical wires, pipes, fences, poles, ropes, cables, vines, shrubs, and trees.
Rats will even climb vertical surfaces including wood, brick, concrete, weathered sheet metal, and plastic. - Rats even use pipes, augers, conveyors, conduit, and underground utility and communications lines to get into a building.

- Rats have continuously growing incisors that grow at the rate of about five (5) inches in a year.
- Rats are limber and can crawl through or under any opening higher or wider than 1/2 inch!
- They climb vertical pipes and conduits up to 3 inches in diameter.
- Rats will brace themselves between a wall and a pipe to climb pipes larger than three (3) inches in diameter to get into a building.
