What You'll Learn

Rats and mice don't like cheese
The idea that rats and mice love cheese is a common misconception that has been perpetuated by folklore and entertainment, such as the classic cartoon setup of a mousetrap baited with a piece of cheese. However, studies have shown that rats and mice are not lured by cheese and may even actively shy away from it due to its strong odour.
Rats and mice have a very strong sense of smell, and their sensitive noses detect the pungent odours of cheese as unpleasant. Instead of cheese, these rodents typically prefer sweet foods such as fruits or grains. They are also opportunistic foragers and will eat whatever is readily available, including meat, insects, and even their own tails if they are hungry enough.
While rats and mice may nibble on cheese if they are hungry and it is the only food available, it is not their preferred food source. The myth that they particularly like cheese may have arisen because, in the past, large amounts of cheese were stored in warehouses, providing an easily accessible food source for rats and mice. However, cheese does not provide all the nutrients that these rodents need, and it is recommended that pet owners limit the amount of cheese they feed their rats and mice.
So, if you're looking to get rid of rats or mice, cheese may not be the most effective bait for your traps. Instead, try using something sweet, like peanut butter or chocolate, which are known to be irresistible to these critters.

Rodents have a strong sense of smell
The idea that rodents are attracted to cheese is a common misconception. In reality, their strong sense of smell means that they are often repelled by the pungent odour of cheese. While hungry rodents may eat cheese if it is the only food available, they do not prefer it and will actively avoid certain types.
Rodents have a very strong sense of smell, with noses that are much more fine-tuned than humans'. Their sensitive noses can detect even subtle odours that are undetectable to us. When it comes to cheese, this strong sense of smell can work against the assumption that rodents are attracted to it. Cheeses, especially those with a strong odour, can emit scents that rodents find off-putting or even repulsive. This sensitivity to smell causes them to turn away from cheese, rather than be lured towards it.
The myth that rodents love cheese is likely due to a combination of folklore, entertainment, and historical factors. The trope of cheese-loving rodents has been perpetuated in popular culture, such as the Tom and Jerry cartoons. Additionally, during the Middle Ages, when this myth first arose, many foods that rodents preferred, such as meats and grains, were stored out of reach, while cheese was more accessible. As a result, rats and mice were often seen eating cheese, creating the misconception that they had a particular affinity for it.
However, it is important to note that rodents are opportunistic foragers. This means that they will consume a wide variety of foods that provide nutritional value, including their own tails or even each other in desperate times. While they may not actively seek out cheese, hungry rodents are known to eat it if other options are scarce. Nonetheless, given a choice, rodents generally prefer sweet foods, grains, fruits, and, depending on the species, meat.
The strong sense of smell in rodents can be used to our advantage when trying to repel or trap them. For example, botanical rodent repellents with natural, fresh scents that are pleasing to humans but off-putting to rodents can be used to effectively keep them at bay. Similarly, when setting traps, baits such as peanut butter, chocolate, or sweets are more effective than cheese, as they are highly enticing to rodents.

Sweet foods are preferred by rodents
Contrary to popular belief, rodents do not particularly like cheese. This is a common misconception, perhaps stemming from the prevalence of this combination in folklore and entertainment, such as the classic cartoon setup of a mousetrap baited with a piece of yellow cheese. However, research suggests that rodents are more likely to turn their noses up at cheese due to its strong smell, which they find off-putting.
So, if cheese is not the preferred food of rodents, what is? Sweet foods are actually the preferred choice for rodents. Given their druthers, rats and mice will generally go for sweets, fruits, and grains, just like many humans! Their preference for sweet foods may be due to their opportunistic foraging nature, which means they will eat most things that supply nutrition. However, it is important to note that different species of rodents may have specific preferences, with some favouring meat over other food groups.
The sweet tooth of rodents has important implications for pest control. For those looking to rid their homes of rodents, it is recommended to keep all food stored securely in containers that keep rodents out. Additionally, the Center for Disease Control advises keeping pet food sealed tightly and ensuring that trash cans and recycle bins are free from holes and have secure lids to reduce the chance of invading rats and mice.
Furthermore, when setting traps, it is more effective to use sweet baits such as peanut butter, chocolate, or even Reese's peanut butter cups, instead of the traditional cheese. This is because rodents will be more attracted to the sweet smell and taste of these alternatives, increasing the likelihood of a successful trap. By understanding the dietary preferences of rodents, we can better protect our food supplies and implement more effective pest control measures.

Peanut butter is a good trap bait
Contrary to popular belief, rodents like mice and rats do not actually like cheese and may even be repelled by its strong smell. While hungry rodents may nibble on cheese, it is not a food source they will seek out.
If you're looking to get rid of rodents, it's important to know what they like and don't like. Rodents are primarily nut and seed eaters, so peanut butter is a highly attractive bait option for traps. Its strong scent is irresistible to indoor and outdoor rodents, boosting your trap's success rate. Peanut butter is also a good option as it is safe to use around children and pets.
The DIY approach of using peanut butter as bait in mouse traps is common, and it can be effective in capturing individual mice. However, it is important to note that this method does not address the root cause of a rodent infestation and is generally ineffective for long-term rodent removal. Dead mice can create unpleasant odors and attract insects, leading to potential health risks. Additionally, relying solely on peanut butter traps can expose you to disease-carrying rodents, their droppings, and urine.
To increase the efficiency of your traps, look for a bait refill pack with a universal twist-in design that fits a wide range of rodent traps. These refills are designed for safe and easy handling, allowing for a hands-free setup and quick rebaiting without direct contact with the bait.
While peanut butter can be a good short-term solution, it is recommended to consult a professional pest control expert for comprehensive and effective long-term solutions. They can implement tailored measures to eliminate the current infestation and prevent future occurrences.

Rats' favourite food is meat
Despite the popular belief that cheese is the best bait for rodents, research shows that mice and rats do not actually like cheese. In fact, the strong smell of cheese may repel them instead of attracting them to a trap. While hungry rodents may eat cheese if it's all they can find, they are not likely to seek it out.
So, what do rats like to eat? Rats are omnivores, and their favourite food is meat. They are also known to scavenge for dead animals, although this is not a primary food source. In urban environments, rats often feed on garbage and leftovers. They are attracted to food with a strong smell, such as peanut butter, and thick, sticky foods can be used as bait because they are difficult for rats to steal without triggering a trap. Rats are also known to eat pet food, especially dry pet food that is left out overnight.
In the wild, rats feed on a variety of seeds and nuts, including sunflower seeds, pumpkin seeds, sesame seeds, walnuts, peanuts, and almonds. These foods provide essential fats, proteins, and other nutrients. Rats also enjoy fruits, which offer a rich source of vitamins, sugars, and water, although they tend to eat fruits in moderation due to their high sugar content. Rats consume various plants, including leaves, stems, and roots, which provide hydration and fiber, and they are especially fond of citrus trees, often stripping the bark from orange and lemon trees.
Rats are smart and need stimulation to stay happy. In their natural environment, they use their intelligence to scavenge for food, and they can be entertained by having to solve puzzles to get their treats. They also love to chew on things to maintain the health of their teeth, so cardboard, coconut shells, and soft wood are good options.
