If you hear sounds from the wall or the attic, especially at night, it's likely that the sounds are related to chewing of a rat. The rats need to control the growth of their teeth, therefore they chew everything. The rats that rush into your house are introduced with the various things they are chewing. People think that rats are found in more wooden houses. Yes that's right, but the rats do not eat the wood, but they only chew it. Wood is very suitable for chewing because of its texture. On the other hand, mice and rats can easily hole the wooden walls and containers to get food. The behavior of mice during a search for food clearly indicates that they eat something that provides them with the most energy they need and less time to achieve. Generally, mice prefer grains, nuts, and cheese.Therefore, it can be said that the rats and mice do not eat the wood, but they chew the woods to prevent excessive growth of their teeth or to find food and build paths.
