Rats can be a troublesome pest, damaging property and spreading diseases. If you have a rat problem, you may be wondering if peanut butter can be used to kill them. The short answer is no, peanut butter alone will not kill rats.

In this comprehensive guide, we’ll cover everything you need to know about using peanut butter for rat control. We’ll discuss how peanut butter can be used in rat traps, look at the pros and cons of this method, explain why peanut butter itself doesn’t kill rats, and provide tips for safe and effective rat control.

Using Peanut Butter in Rat Traps

Peanut Butter is an Effective Bait

When it comes to trapping rats, peanut butter has proven to be an incredibly effective bait. Rats are attracted to the scent and taste of peanut butter, making it an irresistible lure. Its sticky consistency makes it difficult for rats to simply snatch the bait and run away, increasing the chances of successfully catching them.

Additionally, peanut butter is easily spread onto traps, ensuring that the scent wafts through the air and entices nearby rats.

According to a study conducted by the University of California, peanut butter has a success rate of over 80% in rat trapping. This makes it one of the most reliable and efficient baits available. So, if you’re looking to get rid of rats in your home or garden, peanut butter is definitely worth considering.

Snap Traps vs Live Traps

When using peanut butter as bait, you have the option of using either snap traps or live traps. Snap traps are the most commonly used type of rat trap and are designed to kill rats instantly. They are quick and effective, but can be messy and may require frequent disposal of rat carcasses.

On the other hand, live traps are a humane alternative that allow you to catch rats alive and release them elsewhere. These traps are especially useful if you want to relocate rats without causing them harm.

However, it’s important to note that live traps may not be as effective as snap traps when it comes to catching rats, as rats can sometimes be wary of entering them.

Tips for Baiting Traps Effectively

To maximize your chances of successfully trapping rats using peanut butter, here are some tips:

  • Use a small amount: Rats are more likely to take the bait if it is a small, concentrated amount. Smearing a thin layer of peanut butter on the trap will suffice.
  • Place traps strategically: Rats tend to stick close to walls, so it’s best to position traps along the baseboards or in areas where rat activity has been observed.
  • Change the bait regularly: Rats can quickly become accustomed to the scent of bait, so it’s essential to replace it every couple of days to keep it fresh and enticing.
  • Combine with other baits: If you’re having trouble attracting rats with only peanut butter, consider using other baits such as chocolate or bacon. This can help increase the chances of catching them.

Remember, it’s important to use caution and follow safety guidelines when setting up traps to avoid any harm to yourself or others. If you’re unsure about how to handle a rat infestation, it’s always best to consult a professional pest control service.

Why Peanut Butter Itself Doesn’t Kill Rats

Peanut butter is a popular bait used in rat traps, but it is important to note that peanut butter itself does not have any lethal effects on rats. Instead, it serves as an attractive lure to entice rats into the trap. Here’s why:

Not Toxic to Rats

Peanut butter is not toxic to rats. In fact, it is a food source that rats find highly appealing. The strong aroma and taste make it an irresistible treat for them. Rats are opportunistic feeders, and they will readily consume peanut butter if it is available to them.

Contrary to popular belief, rats are not allergic to peanuts. They can digest peanuts and peanut butter without any adverse effects. So, while peanut butter may not be harmful to rats, it does not have any inherent rat-killing properties.

Provides Nourishment

Peanut butter is calorie-dense and contains a good amount of protein, fats, and carbohydrates. While it may not be the healthiest food for humans in large quantities, it can provide rats with the energy and nourishment they need.

This is particularly important when using peanut butter as bait in traps.

When rats consume peanut butter, it fills their stomachs and satisfies their hunger, making them less cautious about approaching traps and more likely to take the bait.

It’s worth noting that while peanut butter itself doesn’t kill rats, it is often used in conjunction with rat traps or rodenticides to effectively control rat populations. Rat traps work by either physically trapping the rat or by delivering a lethal dose of poison, while peanut butter serves as the enticing bait to attract the rats to the trap.

If you’re dealing with a rat infestation, it is always recommended to seek professional pest control assistance to ensure effective and safe rat control measures are implemented.

Pros and Cons of Using Peanut Butter for Rat Control

Pros: It’s an Appealing Bait

Peanut butter is often used as a bait for rat control due to its strong scent and taste that rats find irresistible. Its high fat content makes it a desirable food source for rodents. When placed strategically in traps, peanut butter can effectively lure rats and increase the chances of trapping or poisoning them.

According to a study conducted by the University of Florida, peanut butter was found to be one of the most effective baits for trapping rats. In fact, it outperformed other commonly used baits such as cheese and bacon.

This makes peanut butter a popular choice among homeowners and pest control professionals.

Cons: Can Attract Other Pests

While peanut butter may be a highly effective bait for rats, it does have its drawbacks. One major concern is that it can attract other pests, such as ants or cockroaches, to your home. These pests are also attracted to the sweet and oily scent of peanut butter, which can lead to an infestation if not addressed promptly.

Additionally, if you have pets in your home, they may also be attracted to the peanut butter bait, increasing the risk of them getting caught in the traps or ingesting the poison. It is important to take precautions and ensure that the bait is placed in areas inaccessible to pets.

Other Bait Options

While peanut butter is a popular choice for rat control, there are alternative bait options available. Some commonly used baits include:

  • Cheese: Despite the common belief that rats are attracted to cheese, it is not as effective as peanut butter. Rats are more likely to be drawn to the strong aroma and high-fat content of peanut butter.
  • Chocolate: Similar to peanut butter, chocolate has a strong scent that can attract rats. However, it should be used with caution as it can be harmful to pets.
  • Grains and Seeds: Rats are natural foragers and are attracted to grains and seeds. Common options include oats, rice, or birdseed.

It is important to remember that while bait can be effective in controlling rat populations, it should be used in conjunction with other pest control methods, such as sealing entry points and maintaining cleanliness.

If you are dealing with a persistent rat infestation, it is recommended to seek professional help from a licensed pest control company.

Tips for Safe and Effective Rat Control

Rats can be a nuisance and a health hazard when they invade homes or businesses. While there are various methods to control rat populations, it’s important to do so safely and effectively. Here are some tips to help you in your rat control efforts.

Trapping Best Practices

Trapping is one of the most common and effective methods for getting rid of rats. When setting up traps, it’s important to place them in areas where rats are known to frequent, such as along walls or in dark corners.

Use bait that is enticing to rats, such as peanut butter or cheese, to increase the chances of success. Check traps regularly and dispose of any captured rats in a safe and sanitary manner.

Preventing Access and Entry

One of the best ways to control rats is to prevent them from entering your property in the first place. Seal any cracks or openings in your walls, floors, and foundation to deny rats easy access. Keep your property clean and free of clutter, as rats are attracted to areas with food and shelter.

Store food in sealed containers and promptly clean up any spills or crumbs to reduce the likelihood of attracting rats.

Natural Rat Repellents

There are several natural repellents that can help deter rats from your property. Peppermint oil, for example, has a strong scent that rats find unpleasant. Soak cotton balls in peppermint oil and place them in areas where rats are likely to be present.

Another natural repellent is ammonia, which can be diluted with water and sprayed in rat-prone areas. However, it’s important to note that while these repellents may be effective in deterring rats, they may not eliminate an existing infestation entirely.

When to Call a Professional

If your rat control efforts are not yielding the desired results or if you’re dealing with a large infestation, it may be time to call in a professional pest control company. They have the knowledge, experience, and tools to effectively eliminate rats and prevent future infestations.

Professional pest control services can also provide guidance on the best prevention measures to keep rats away from your property.

Remember, when dealing with rats, it’s crucial to prioritize safety and effectiveness. Implementing these tips can help you achieve a rat-free environment and protect your property from the potential damage and health risks associated with rat infestations.


While peanut butter itself does not kill rats, it can be an useful tool when used properly in rat traps. Combining traps with exclusion methods and removing food sources will lead to the most effective rat control.

We’ve covered how peanut butter baits traps by attracting rats, but also some downsides to be aware of. Implementing the tips provided can help you safely and humanely manage a rat problem.
