An adult rat can squeeze into your home through a hole as small as the size of a quarter.

Rats can live for up to 18 months, but most die before they are one year old.

Rats have strong teeth that allow them to chew through glass, cinderblock, wire, aluminum and lead.

Smell, taste, touch and sound help direct them to their food sources.

Rats are also responsible for spreading bubonic plague, also known as the “Black Death”. Although fleas are primarily responsible for infecting humans, they were originally infected with the plague by feeding on the blood of rats.

Rats are scavengers. They have an excellent sense of taste and a good memory. A rat can identify certain substances, including rat poisons, after just a tiny taste of it.
