They will become bold after time and bites associated with rats are as a result of them getting to close. Rat bites are a very serious matter and it is never a good idea to corner any animal of this size. They will eat all types of grain, fruit, nuts, meats and even fish. The view that rats only eat garbage is totally false. Rats will get most of their water from their food, however they will drink fresh water when necessary.
Rats can become a serious problem in communities bordering farmland.
Rats unearthed or scattered, as old farm buildings are torn down, will migrate into suburban areas and find harborage under slabs of concrete, shrubs, retaining walls and inside homes. A single female will wean an average of 24 offspring each year. These young are born underground and like the adults are nocturnal in nature. Norway rats have a highly developed sense of taste and touch and will be able to detect contamination levels of as little as 0.4 parts per million in food. When baiting them, great care needs to be made to keep bait free from anything repellent or risk having the rat refuse to eat and as a result become bait shy.
