Rats, those ubiquitous rodents we often encounter, are remarkably adaptable omnivores with a diet as varied as the environments they inhabit. Understanding “What Do Rats Eat” is crucial, not just for general knowledge, but especially for effective pest management. Their sharp teeth, constantly growing, necessitate continuous gnawing, influencing their feeding habits and the types of food they are attracted to.
In their natural habitats, rats tend towards a more vegetarian diet, primarily consuming fruits, plants, and seeds. However, urban rats have become masters of scavenging, readily feasting on garbage, meat scraps, pet food, and discarded human food. This adaptability is key to their survival and proliferation in human-dominated landscapes. To effectively deter these resilient pests, securing food sources and properly sealing trash bins are essential first steps. Delving into their dietary preferences provides valuable insights into their behavior and is fundamental in developing robust pest control strategies.

What Attracts Rats to Your Yard?
Rats are drawn to yards primarily by the promise of three essential resources: food, water, and shelter. A careful inspection of your yard can reveal numerous potential attractants for these resourceful rodents. Shelter can be found in a variety of forms, from untidy stacks of firewood and piles of bricks to general clutter and accumulated debris. Overgrown vegetation, sheds, and garages also offer ideal hiding spots.
Water sources, often overlooked, are equally critical for rats. Leaky outdoor faucets, poorly draining storm drains, birdbaths, and even pet water bowls can provide ample hydration. Even condensation from air conditioning units can be a sufficient water source.
When it comes to food, rats are far from picky eaters. They will readily consume seeds scattered from bird feeders, grains left in open bags, unsecured garbage, pet food left outdoors, fallen fruits from trees, nuts, vegetables growing in gardens, and accessible compost heaps. The increasing urbanization has further conditioned rats to thrive in close proximity to humans, making them adept at scavenging from garbage cans, pet waste, and even fruit-bearing trees within city limits. Minimizing these readily available resources is key to making your yard less inviting to rats.
What Attracts Rats into Your Home?
Homes offer rats a haven, particularly during colder seasons when external food sources become scarce and temperatures drop to levels that are challenging for survival. The primary drivers for rats entering homes are the same as for yards: food and shelter. Rats are omnivorous scavengers, and a home provides a smorgasbord of potential food items. They will readily consume garbage, dry grains stored in pantries, pet droppings if accessible, and fruits left on countertops.
Inside homes, rats are particularly attracted to cereals, oats, rice, improperly stored vegetables, and pet food. Unsealed garbage cans in kitchens and the lingering residues of oils or fats on kitchen surfaces and stoves are also highly enticing. Even crumbs left under appliances can become a food source.
Beyond food, rats seek out warm, dark, and secluded spaces for nesting and raising their young. Common nesting locations within homes include infrequently used furniture, cluttered storage boxes, and the insulation within walls or attics. They can also nest in basements, crawl spaces, and behind appliances where it is warm and undisturbed. Sealing entry points and decluttering potential nesting areas are crucial steps in preventing rats from establishing themselves inside your home.
How Rats’ Diets Have Adapted to Their Environment
Rats are incredibly adaptable omnivorous scavengers that have evolved to flourish in a wide range of habitats, developing broad and highly varied diets. While the specific composition of a rat’s diet can differ significantly based on its geographical location and available resources, certain feeding behaviors remain remarkably consistent across species and environments.
One such characteristic behavior is their tendency to nibble on unfamiliar foods. This is not an indication of picky eating habits, but rather a vital survival strategy known as “food neophobia.” By initially consuming only a small quantity of a new food source, rats can assess its safety. If they experience any adverse effects or illness after eating a small amount, they learn to avoid that particular food in the future. This adaptive behavior is highly advantageous in environments where food sources may be unpredictable or potentially toxic.
This cautious approach to new foods also helps explain why some rodent control methods may become less effective over time. Rats can learn to associate certain baits or lures with potential dangers, especially if they experience sublethal poisoning or trapping attempts. This learning ability underscores the importance of varying pest control strategies and using effective, palatable baits to overcome rat’s natural food neophobia and adaptability.
What Do Rats Like to Eat?
While rats are opportunistic feeders, consuming a vast array of items, they do exhibit distinct food preferences based on their environment and species. In more natural settings, a rat’s diet predominantly consists of grains, seeds, nuts, fruits, and occasionally smaller animals or insects. These food sources provide a balanced mix of carbohydrates, proteins, and fats necessary for their survival.
However, in human-dominated areas, rat diets become significantly more diversified due to the readily available abundance of human-generated resources. Norway rats, for instance, exhibit a notable preference for protein-rich foods, such as meat scraps, pet food, and even fish. This preference is likely linked to their larger size and higher protein requirements compared to some other rat species.
Roof rats, also known as ‘fruit rats,’ are aptly named due to their pronounced preference for fruits. This dietary inclination explains their natural tendency to climb trees and shrubs, as these are prime locations for finding fruits and berries. Their agility in climbing also allows them to access food sources in elevated locations, such as attics and rooftops.
Regardless of the specific species, rats’ remarkable adaptability allows them to efficiently locate and scavenge food from diverse sources, including garbage cans, compost piles, and open food containers. To effectively mitigate rodent infestations, homeowners and businesses must focus on minimizing accessible food sources and consider consulting with a pest control expert to implement comprehensive and tailored solutions.
Do Rats Eat Plants?
Rats in the wild are indeed known to consume a wide variety of plants, seeds, and grains as a staple part of their diet. Fruits and berries are particularly appealing to them due to their ease of access, sweet taste, and high energy content. These sugary foods provide a quick and readily available source of carbohydrates.
While fruits are often preferred when available, rats will also readily consume vegetables if they are easily accessible, such as in gardens or improperly stored produce. Vegetable gardens can inadvertently attract rats not only due to the vegetables themselves but also because gardens often harbor snails, slugs, and other insects, which serve as supplementary protein sources for rats.
To help prevent rat infestations around homes and gardens, it is crucial to maintain a clean outdoor environment and promptly harvest fruits and vegetables from gardens and fruit trees. Removing fallen fruit and vegetables and securing compost piles can significantly reduce the attractiveness of your yard to rats.
Do Rats Eat Meat?
Rats are classified as omnivores, meaning they are biologically capable of and will readily consume meat if they have the opportunity. However, meat is not always a primary component of their diet, particularly for rats in wilder environments, as meat can be relatively harder to come by compared to plant-based food sources. Rats are not natural predators, and therefore, they primarily rely on scavenging for meat rather than actively hunting prey.
Due to their close proximity to human habitats, urban rats typically have a much higher chance of encountering and feasting on remnants of meat-based foods discarded by humans, such as hamburger and hotdog scraps, chicken bones, and other meat leftovers found in garbage. Rats may also resort to eating fresh roadkill or carrion when available, and they commonly consume insects like worms, snails, and beetles as a source of animal protein. Insects can be a more consistent and reliable meat source, especially for rats living in gardens or areas with abundant insect populations.
Do Rats Eat Nuts and Seeds?
Nuts and seeds are highly favored food items for rats, primarily due to their high protein and fat content. Rats have a constant need for protein in their diet for growth and maintenance, and while they will obtain protein from various sources, wild rats often find it more challenging to access protein in the form of meat.
Instead of actively hunting prey, rats prioritize foraging for readily available plant-based foods like fruits, berries, and plants that can offer them essential calories, vitamins, and nutrients. When it comes to efficiently fulfilling their protein requirements from plant sources, nuts and seeds emerge as ideal and readily available options. Seeds are particularly convenient for rats to handle and consume, making them a highly desirable and nutritionally valuable dietary component for these rodents. They will often hoard nuts and seeds to store for later consumption.
Do Rats Eat Eggs?
Eggs are considered a protein-rich delicacy that rats are particularly fond of and will actively seek out when available. While the size of a chicken egg might seem disproportionately large compared to a rat, they are surprisingly adept at maneuvering and consuming eggs. It is not uncommon for farmers and poultry owners to observe rats stealing chicken eggs from nests and maneuvering them back to their burrows or nests to consume.
In wilder environments, rats might more frequently encounter smaller bird eggs, but their enthusiasm for eggs as a food source remains consistently high regardless of the egg size. The primary allure of eggs for rats lies in their exceptional nutritional value. Eggs are densely packed with essential proteins, vitamins, minerals, and calories, offering a comprehensive dietary boost in a single, easily accessible package. Procuring an egg is also a relatively low-risk and energy-efficient endeavor for rats, making them a highly attractive and rewarding food source.
What Foods are Toxic to Rats?
While rats have remarkably resilient digestive systems, certain foods can be harmful or even toxic to them. It is essential to be aware of these potentially dangerous foods, especially if you keep rats as pets or are attempting to control rat populations without resorting to lethal poisons within your home. Feeding toxic foods to rats can lead to a range of health issues, from mild discomfort to severe complications and, in some cases, death. Using these foods in rat control is not recommended as it can cause rats to die within walls, leading to unpleasant odors and further complications.
The following is a list of foods that should not be given to rats under any circumstances:
- Blue Cheese: Contains high levels of mold and can produce toxins harmful to rats.
- Licorice: Contains glycyrrhizin, which can be toxic to rats in large quantities.
- Poppy Seeds: Contain opium alkaloids that can be harmful to rats.
- Bitter Almonds: Contain cyanide, which is highly toxic.
- Green Potatoes: Contain solanine, a toxic alkaloid, especially in the sprouts and skin.
- Rhubarb Stems and Leaves: Contain oxalic acid, which is toxic and can cause kidney damage.
- Fungus on Grains: Can produce mycotoxins harmful to rats.
- Caffeine: Can cause hyperactivity, seizures, and cardiac issues.
- Lemon Peels: Contain psoralens, which can be phototoxic and irritating.
- Mango: Mango skin contains urushiol, similar to poison ivy, which can cause allergic reactions.
What Food is Best for Trapping Rats?
Selecting the right bait is absolutely critical when you are attempting to trap rats effectively. Rats are most strongly drawn to foods that are rich in nutrients, fat, and protein. Based on their natural food preferences and extensive successful trapping experiences, the following foods have consistently proven to be highly effective bait options for rat traps:
- Peanut Butter: Its strong aroma, high fat and protein content, and sticky texture make it incredibly attractive to rats.
- Bacon: The strong smell and high fat and protein content of bacon are irresistible to rats.
- Dried Fruit: Sweet, chewy, and aromatic, dried fruits like raisins or dates are excellent lures.
- Chocolates: The sweet and fatty nature of chocolate, especially dark chocolate, is highly appealing to rats.
It is important to strategically place the bait within the trap in a way that maximizes its effectiveness and accessibility for the rats. Rats often exhibit a cautious feeding behavior, taking small nibbles of unfamiliar food sources before fully committing to consuming them. Therefore, combining these highly attractive treats with a sticky binder, such as peanut butter, significantly increases the likelihood of a rat fully engaging with the bait and triggering a snap trap mechanism.
Offering a variety of baits initially can also be beneficial in helping to quickly identify a rat population’s specific food preferences in your area. Once a preferred bait is determined through initial trials, that specific bait can be consistently used in rat traps placed strategically around the house or property for optimal trapping success.
