Do Rats Eat Wood?

Written by: Gemmali Dizor

Are you a homeowner, business owner, or simply someone concerned with maintaining a clean and healthy environment? You may have wondered if rats eat wood. It’s an often-held misconception that rats will munch on anything in sight – including wood. But is this really true? In this article, we’ll investigate this topic thoroughly and provide all of the information necessary for making an informed decision about whether rats eat wood.

What Do Rats Eat?

Before we explore whether rats eat wood, let’s first examine what they typically eat. Rats are opportunistic feeders, meaning they will consume almost anything they can find. In the wild, rats often eat fruits, nuts, seeds, and insects while urban areas often see rats scavenge for food in trash cans, dumpsters, or inside buildings.

Rats have also been known to eat other rodents and small animals, including meat. Some species of rats may even be cannibalistic – meaning they will consume other rats.

Do Rats Eat Wood?

Rats are known to occasionally chew on wood for various reasons, though this behavior has not been scientifically confirmed. While they generally don’t consume wood as their primary food source, rats may chew on it for various reasons.

One reason rats chew wood is to keep their teeth healthy. Like all rodents, rats have teeth that continue to develop throughout life; thus, to prevent these from overgrowing, rats must gnaw on hard surfaces like wood to wear them down and wear away at their enamel. You’ll often spot rat teeth marks on wood, wires, pipes, and other hard surfaces such as furniture.

Another reason rats may chew on wood is to gain access to food or shelter. Rats have the capacity to chew through wood in order to create holes and burrows, giving them access to food sources or creating nests. Therefore, it’s essential that you seal off any openings or gaps in your home or building in order to prevent rats from entering.

Finally, rats may simply chew on wood out of boredom. Rats are intelligent animals who require mental stimulation to remain healthy and contented. Without something to occupy their time with, they may turn their attention towards chewing on wood or other objects.

Is Wood Dangerous for Rats to Consume?

Rats may chew on wood, but it’s not a nutritious or healthy food source for them. In fact, some types of wood can be hazardous if eaten; treated wood contains chemicals that could be toxic if ingested by rats. Furthermore, splinters from any type of wood may cause injury or infections if they get stuck in a rat’s mouth or digestive tract.

How to Prevent Rats from Chewing on Wood?

If you’re worried about rats chewing through the wood in your home or building, there are several steps you can take to prevent this behavior. Here are a few suggestions:

Stop rats from entering and creating burrows or nests in your home or building by sealing any openings or gaps.

Food should always be stored in airtight containers to reduce the likelihood of rats chewing through the wood to get at it. To keep your food secure, keep food out of reach from rodents by keeping food items stored securely.

Give rats alternative chewing options. Rats need to chew regularly in order to keep their teeth healthy, so providing them with appropriate objects to chew on will help prevent them from chewing through wood. Try giving them wood blocks, chew toys, or dog bones as alternatives for wood chewing.

Rat repellents. There are various rat repellents on the market, such as electronic devices, sprays, and granules that can help deter rats from entering your home or building and chewing through wood. These methods will help deter rodents from chewing through electrical wiring or chewing on wood surfaces.


Rats typically do not consume wood as a primary food source, but they may chew it for various reasons such as keeping their teeth healthy, accessing food or shelter, or out of boredom. Unfortunately, wood is not considered to be a nutritious or healthy food source for rats, and some types of wood can even pose risks if ingested.

If you’re worried about rats chewing on wood in your home or building, there are steps you can take to prevent it. Seal any openings and gaps, store food in secure containers, provide appropriate chewing options for rats, and use rat repellents – these all work to discourage rats from entering your space and chewing on wood.

In addition to these preventive measures, it’s essential to keep your environment tidy and uncluttered. Rats tend to congregate around messy or unclean places, so by keeping a neat space you can reduce the likelihood of an infestation and stop them from chewing through wood or other objects.

Overall, while rats may chew on wood for various reasons, it is essential to take steps to prevent them from doing so in order to ensure a healthy and safe environment. By understanding why rats chew on things and taking preventive measures against it, you can keep your home or build free of damage caused by rats while safeguarding yourself as well as others from potential risks.
