Rats are notorious for their ability to chew through various materials, including walls, which can lead to significant damage to properties and pose health risks to occupants. Understanding how long it takes for a rat to chew through a wall can help homeowners and property managers take proactive measures to prevent infestations and mitigate potential damage. In this article, we will delve into the factors that influence a rat’s chewing ability, the types of materials they can chew through, and provide estimates of the time it takes for a rat to chew through different types of walls.
Factors Influencing a Rat’s Chewing Ability
Several factors can affect a rat’s ability to chew through walls, including:
Rat Species
There are over 60 species of rats, but the most common ones found in homes and buildings are the Norway rat (Rattus norvegicus) and the roof rat (Rattus rattus). These two species have different chewing abilities, with Norway rats being more powerful and capable of chewing through thicker materials.
Age and Health
Younger rats tend to be more energetic and have sharper teeth, making them more efficient chewers. Older rats, on the other hand, may have worn-out teeth and reduced energy levels, slowing down their chewing pace. Rats with health issues, such as malnutrition or dental problems, may also have impaired chewing abilities.
Material Type and Thickness
The type and thickness of the material being chewed through significantly impact a rat’s chewing speed. Rats can chew through softer materials like wood, plastic, and drywall more quickly than harder materials like metal, concrete, or brick.
Temperature and Humidity
Extreme temperatures and humidity levels can affect a rat’s chewing ability. Rats are more active in temperatures between 68°F and 90°F (20°C and 32°C) and humidity levels between 50% and 80%. Outside of these ranges, their chewing speed may slow down.
Types of Materials Rats Can Chew Through
Rats are capable of chewing through a wide range of materials, including:
Wood
Rats can easily chew through wood, especially if it’s softwood or rotten. They can gnaw through wooden beams, joists, and studs, causing significant structural damage.
Drywall
Drywall is another common material that rats can chew through. They can create holes and tunnels in drywall, often using their sharp teeth and powerful jaws to break through the gypsum core.
Plastic
Rats can chew through various types of plastic, including PVC pipes, plastic containers, and insulation materials.
Insulation
Rats often target insulation materials like fiberglass, cellulose, and foam board. They can chew through these materials to create nests and tunnels.
Estimating the Time it Takes for a Rat to Chew Through a Wall
The time it takes for a rat to chew through a wall depends on the factors mentioned earlier. However, here are some general estimates based on the type of material and thickness:
Wooden Walls

Q: How long does it take for a rat to chew through a wall?
The time it takes for a rat to chew through a wall depends on various factors, including the type of material the wall is made of, the size and determination of the rat, and the availability of food and water on the other side. Generally, rats can chew through soft materials like drywall, plywood, or plastic in a matter of hours or days. However, harder materials like concrete, metal, or brick may take longer, sometimes up to several weeks or even months.
It’s also worth noting that rats are persistent creatures and will continue to chew and gnaw on a surface until they create an opening. They can chew through a surprising amount of material in a short amount of time, especially if they are motivated by the promise of food or shelter. Homeowners who suspect they have a rat infestation should take immediate action to seal any holes or gaps in their walls to prevent further damage.
Q: What types of walls are most vulnerable to rat chewing?
Rats are most likely to chew through walls made of soft materials, such as drywall, plywood, or plastic.
