Rats and chipmunks are two common backyard creatures that sometimes cross paths. If you’ve seen rats scurrying around your yard and wonder if they pose a threat to local chipmunks, you’re not alone.

If you’re short on time, here’s a quick answer to your question: Yes, rats will eat chipmunks if given the opportunity. However, they do not typically hunt chipmunks and are more likely to scavenge any remains they come across.

In this comprehensive guide, we’ll dive into rat and chipmunk behaviors and habitats to better understand if and when rats may prey upon chipmunks. We’ll also provide tips on protecting any chipmunks that may live on or visit your property.

Do Rats Actively Hunt Chipmunks?

When it comes to the question of whether rats actively hunt chipmunks, the answer may come as a surprise. While rats are known to be opportunistic omnivores, their primary diet typically consists of grains, fruits, and vegetables.

However, under certain circumstances, rats have been known to prey on smaller animals, including chipmunks.

Rats Are Opportunistic Omnivores

Rats are highly adaptable creatures with a wide-ranging diet. They are opportunistic omnivores, meaning they will consume whatever food sources are readily available to them. Their diet can include fruits, vegetables, seeds, nuts, insects, and even small animals.

This adaptability allows rats to survive in various environments, including urban areas.

Chipmunks Are Not a Primary Prey Source

While rats have been known to prey on chipmunks, it is important to note that chipmunks are not a primary prey source for rats. Chipmunks primarily feed on seeds, nuts, fruits, and insects, and they are not typically a significant part of a rat’s diet.

Rats are more likely to target smaller animals such as mice or birds, which are easier to catch and consume.

Exceptions: Rat Predation in Urban Areas

There have been reports of rat predation on chipmunks in urban areas where food sources may be limited. In these cases, rats may resort to hunting smaller animals as a means of survival. Urban environments often provide rats with abundant sources of human food waste, but when these sources are scarce, rats may turn to other prey, including chipmunks.

It is important to note that rat predation on chipmunks is not a common occurrence and is more likely to happen in specific circumstances. If you are experiencing issues with rats or chipmunks in your area, it is recommended to contact a professional pest control service to address the problem effectively.

When Might Rats Eat Chipmunks?

Rats are known to be opportunistic omnivores, meaning they will eat just about anything they can find. While it is not their primary food source, rats have been known to eat chipmunks under certain circumstances.

Scavenging Opportunistically

Rats are scavengers by nature, and if they come across a deceased chipmunk, they may not hesitate to consume it. Rats are attracted to the smell of decaying flesh, and a dead chipmunk would be no exception.

In urban areas where chipmunks and rats coexist, the likelihood of rats scavenging on chipmunks increases.

Eating Chips After Other Predators’ Kills

Rats are known to scavenge the leftovers from other predators’ kills. If a larger predator, such as a hawk or a snake, captures and kills a chipmunk, there is a possibility that rats may find the carcass and feed on it.

This behavior is not exclusive to chipmunks, as rats have been observed scavenging on various small animals.

Consuming Weak, Injured, or Baby Chipmunks

While rats primarily feed on plant matter, they are known to prey on weak, injured, or baby animals when the opportunity arises. If a chipmunk is injured or unable to defend itself, rats may see it as an easy target and seize the opportunity to consume it.

However, it is important to note that this behavior is not common and occurs infrequently.

It is worth mentioning that chipmunks are agile and quick, making it challenging for rats to catch them. Chipmunks also have the ability to climb trees, which further reduces the chances of rats preying on them. While rats may occasionally eat chipmunks, it is not a common occurrence in their diet.

How to Protect Chipmunks from Rats

If you have chipmunks in your backyard, you may be concerned about the presence of rats. While it may be surprising, rats do occasionally prey on chipmunks. To ensure the safety of these adorable creatures, it’s important to take measures to protect them from rats.

Here are a few effective ways to do so:

Remove Food Sources That Attract Rats

Rats are attracted to areas where they can find food easily. To prevent them from coming into your yard and potentially harming chipmunks, it’s crucial to remove any food sources that may be enticing to rats.

This includes securing garbage cans tightly, cleaning up fallen birdseed, and storing pet food in sealed containers. By eliminating these food sources, you can minimize the chances of rats being attracted to your yard.

Seal Up Possible Entry Points

Rats can squeeze through small openings, so it’s important to seal up any possible entry points in and around your property. Inspect your home and yard for cracks, gaps, and holes that rats could use to gain access. Seal these openings with steel wool or caulk to prevent rats from entering.

Additionally, make sure your windows and doors have proper screens and weatherstripping to keep rats out.

Use Humane Rat Control Methods

If you have a rat problem in your area, it’s essential to address it without causing harm to chipmunks or other wildlife. Instead of using lethal traps or poisons, consider using humane rat control methods.

These may include live traps that allow you to capture rats and release them safely away from your property. Remember to check local regulations regarding the relocation of rats before using these methods.

By implementing these strategies, you can help protect chipmunks from the potential threat of rats. Creating a rat-free environment will ensure the safety and well-being of these adorable creatures and maintain the natural balance in your yard.

Signs of Rat Activity Around Chipmunks

Seeing Rats Near Chipmunk Burrows

If you have noticed rats near chipmunk burrows, it could be a sign of rat activity around chipmunks. Rats are opportunistic feeders and will not hesitate to take advantage of an easy meal. Chipmunk burrows provide a sheltered environment that rats may find appealing.

While rats and chipmunks may coexist in the same area, it is important to monitor the situation closely to ensure the safety of the chipmunks.

Finding Partially Eaten Chipmunk Remains

Finding partially eaten chipmunk remains can be a clear sign that rats are preying on chipmunks. Rats are known to be voracious eaters and may attack chipmunks if they come across them. If you discover such remains, it is essential to take action to prevent further harm to the chipmunk population.

Implementing measures to deter rats, such as removing potential food sources and securing chipmunk burrows, can help protect chipmunks from becoming prey.

Noticing Fewer Chipmunks Over Time

If you have noticed a decline in the chipmunk population in your area over time, it could indicate that rats are eating chipmunks. Rats are known to be efficient hunters, capable of decimating small rodent populations.

If chipmunks are disappearing from your yard or surroundings, it is important to investigate whether rats are the cause. Taking steps to control the rat population and create a less attractive environment for them can help protect chipmunks and preserve their population.

For more information on rat behavior and their impact on other small animals, you can visit the National Geographic website. They provide comprehensive insights into rat behavior and their interactions with other animals.


While rats do not typically hunt healthy adult chipmunks, they are opportunistic omnivores that will feed on vulnerable or deceased chipmunks they come across. By sealing up entry points, removing outdoor food sources, and using humane rat control methods, you can reduce interactions between rats and chipmunks in your yard.

Keep an eye out for signs of rat predation so you can take action to protect local chipmunk populations if needed.
