Do you know that Rats’ front teeth (incisors) grow 5 inches per year? Their teeth grow continuously throughout their life. Therefore, naturally if they don’t gnaw on things, their teeth will grow longer than their bodies. This makes them most destructive structural pest.
It is an established fact that rats can cause great destruction with their powerful teeth and jaws — jaws so powerful that they can bite through lead!
RATS BIOLOGY AND HABITS
Rats are some of the most troublesome and damaging rodents in India. They consume and contaminate food, damage structures and property, and transmit parasites and diseases to other animals and humans. Rats habitat and thrive under different climatic conditions. They are often found in and around homes and other buildings, farms, gardens, etc.
Their nests are built from soft material like paper or grass chewed into small pieces. Rats will climb if necessary to enter a building. Some species of rats are excellent swimmer. The common species of rats found in India are Mus musculus (house mouse), Rattus rattus (roof rat), Mus musculatus (mice) and bandicoots (Big Rats).
Rats of either species, especially young once, can squeeze beneath a door with only a 2 cm gap. If the door is made of wood, the rat may gnaw to enlarge the gap.
