Squirrels and rats, often encountered in both urban and natural landscapes, are frequently mistaken for one another due to their similar size and ubiquitous presence. While they share some common traits, understanding the distinctions between them is crucial, especially when dealing with potential infestations or simply wanting to appreciate wildlife around your home.
Both squirrels and rats belong to the order Rodentia, but pinpointing their specific differences in physical attributes, behavior, and habits can be incredibly helpful for homeowners and nature enthusiasts alike. Differentiating them accurately allows for targeted pest management strategies and a deeper appreciation for each creature’s unique role in the ecosystem.
So, what exactly sets squirrels apart from rats? While both are rodents, this article will delve into their key differences across several categories, including physical appearance, behavior patterns, droppings, and the type of damage they cause. We’ll also explore their shared characteristics as members of the rodent family and address the question: Is A Squirrel In The Rodent Family? This comprehensive comparison will provide you with the knowledge to confidently distinguish between these two common animals.
Squirrels Vs. Rats: Key Distinctions
When faced with a potential rodent issue, accurately identifying whether you’re dealing with squirrels or rats is the first step towards effective management. Understanding their differences can inform your approach to deterring them and protecting your property. Here are four primary categories to examine when distinguishing between squirrels and rats:
1. Physical Appearance: Size, Tail, Fur, Head, and Limbs
Observable physical traits offer immediate clues to differentiate squirrels and rats. From their size to the texture of their fur, several visual characteristics can help you tell them apart. The table below summarizes these key physical differences:
| Characteristic | Rat | Squirrel |
|---|---|---|
| Size | Adult rats can grow up to 16 inches long from nose to tail. | Adult squirrels typically range from 15 to 20 inches in length, including their tail. |
| Tail | Rats possess tails that are thin, scaly, and often held vertically. | Squirrels are known for their bushy tails, covered in dense, bristly fur. Their tails are usually held upwards when standing or sitting, often “flopping” and curling rather than remaining strictly vertical. |
| Fur | Rat fur can be various shades of brown, grey, black, or white. | Squirrel fur is commonly a mix of grey and brown. Notably, squirrels also have fur on their feet and tails, unlike rats. |
| Head | Rats have heads that are more pointed in shape, featuring proportionally smaller eyes. | Squirrels have blunter heads compared to rats, with eyes that appear larger in proportion to their head size. |
| Limbs | Rats have moderately long legs with narrow hind feet. Their feet and “hands” appear hairless. | Squirrels have distinctly large hind legs and smaller forepaws. Their forepaws end in delicate, finger-like digits resembling a human hand. |
2. Behavior: Eating Habits, Sleep Schedules, Nesting, and More
Beyond physical traits, behavior provides another crucial layer of distinction between rats and squirrels. Their daily routines, dietary preferences, and nesting habits differ significantly. Let’s explore these behavioral differences in more detail:
| Characteristic | Rats | Squirrels |
|---|---|---|
| Eating habits | Rats are omnivorous and opportunistic eaters, consuming almost anything available. Their diet includes nuts, grains, seeds, fruits, vegetables, and even human snacks (both sweet and salty). They are also more inclined to eat meat, sometimes even scavenging roadkill. | Squirrels are primarily herbivorous, though they are not strictly picky eaters. Their diet mainly consists of nuts, roots, seeds, mushrooms, and insects. In times of food scarcity, squirrels may occasionally prey on smaller animals, including rats. |
| Sleep schedule | Rats are nocturnal, primarily active during the night. This nocturnal activity is due in part to their poor eyesight; they rely heavily on their whiskers and keen sense of smell to navigate in the dark. You’re more likely to hear rats at night. | Squirrels are diurnal, meaning they are most active during the daytime. Flying squirrels are an exception, as they are nocturnal. Squirrels’ diurnal nature is supported by their excellent eyesight, including sharp peripheral and vocal vision, enabling them to see threats and food sources efficiently during the day. |
| Nesting habits | Rats typically nest in gardens or underground burrows, favoring overgrown areas with rich soil. Indoors, they seek out warm materials like cardboard, shredded paper, and cotton to build nests in secluded, lower areas of homes such as basements, garages, cabinets, and drawers. | Squirrels prefer nesting in tree cavities, constructing nests from leaves and dry twigs, often high above ground (60 feet or more). Indoors, they tend to inhabit attics, ceilings, and walls. Unlike rats, some squirrel species hibernate during winter. |
| Life cycle | Rats are highly prolific breeders, with females capable of producing up to 6 litters per year. Their average lifespan is relatively short, ranging from 1 to 4 years, with captive rats often living longer than those in the wild. | Squirrels typically mate twice a year, resulting in two litters annually. They generally have longer lifespans than rats, averaging 5 to 20 years, depending on the species and living environment (wild vs. captivity). |
| Movement | Rat movement is characterized by “scurrying” – quick, darting motions, especially when disturbed. They tend to run low to the ground and are less likely to stand upright due to their body size and shorter tails. Rats are also adept swimmers, sometimes entering homes through drainpipes and toilets. | Squirrels move by bounding or hopping, creating an up-and-down motion. They are frequently observed standing upright, a posture less common in rats. |
| Sounds produced | Rats produce squeaking or chattering sounds, primarily at night. They may also hiss when in pain and create scratching noises on surfaces like walls and ceilings. | Squirrels are known for sharp, distinctive cries, often described as “quq” or “kwa” sounds, typically heard during the day. Scratching sounds can also indicate their presence indoors. |
3. Droppings: Clues in Waste
Examining rodent droppings can provide further clues to whether you are dealing with rats or squirrels. While visually similar at first glance, subtle differences and patterns in their waste habits can help in identification.
One significant difference lies in how they mark territory. Rats establish “urine pillars” as pathways, which become visible as grease marks or dark smears on walls along their routes. Squirrels, however, do not create these urine trails. Instead, they are more likely to deposit droppings in concentrated areas, typically near their nests or feeding spots, rather than scattering them along travel paths. This difference in waste distribution can be a helpful indicator.
4. Damage Caused: Garden and Home Impact
The type of damage inflicted can also help distinguish between rats and squirrels, even without direct sightings. Observing patterns of damage, especially in gardens, can offer clues.
Rats, being nocturnal, usually cause damage overnight. Gardeners might find fruits and vegetables eaten in the morning, with damage appearing to have occurred under the cover of darkness. Squirrels, being diurnal, are often seen in the act of causing damage during daylight hours, particularly around trees and feeding areas.
Examining chewed fruits and vegetables closely can also reveal differences. For citrus fruits like oranges, rats tend to consume the entire fruit, leaving only the peel hanging on the tree. Squirrels, conversely, often leave partially eaten fruits scattered on the ground. Rats are also more likely to target and damage vegetables compared to squirrels.
Are Squirrels Rodents? Understanding the Rodent Family
Yes, a squirrel is indeed in the rodent family. This is a fundamental aspect of squirrel classification. The term “rodent” originates from the Latin word “rodere,” meaning “to gnaw.” This aptly describes the defining characteristic of rodents: their continuously growing incisor teeth. With over 2,050 species, rodents represent the most diverse order of mammals on Earth.
Despite their wide range of appearances and habitats, all rodents share key features. The most prominent is their pair of perpetually growing incisors in both their upper and lower jaws. These teeth require constant gnawing to keep them trimmed and functional. Rodents typically possess compact, sturdy bodies, relatively short limbs, and notably long tails. Behaviorally, many rodent species are known for their nesting and burrowing habits, further uniting this diverse group.
Similarities of Squirrels and Rats: Shared Rodent Traits
Beyond their shared classification as rodents, squirrels and rats exhibit several other similarities. These common traits underscore their relatedness within the mammal family:
- Mammalian Classification: Both squirrels and rats are mammals, characterized by fur-covered bodies and reproduction through live birth. This places them within the class Mammalia, highlighting their shared biological heritage.
- Powerful Teeth: Both possess strong teeth that grow continuously throughout their lives. This necessitates constant gnawing on various materials to wear down their teeth and keep them at a manageable length. This shared dental characteristic often leads to property damage as they gnaw on walls and furniture. Both also have complex jaw structures and powerful masseter muscles attached to the jaw and skull, providing the strength needed for persistent chewing and gnawing.
- Intelligence: Both squirrels and rats are recognized for their intelligence. Rats are frequently used in behavioral studies due to their problem-solving abilities, while squirrels are known for their remarkable spatial memory, particularly in remembering the locations of buried food caches.
Are Squirrels Considered Pests? Addressing the Pest Status
While rats are often immediately labeled as pests due to their disease-carrying potential and destructive habits indoors, squirrels’ pest status is sometimes underestimated. Although often perceived as cute outdoor creatures, squirrels can indeed become significant pests, causing considerable damage to property.
Squirrel-related damages include:
- Garden Devastation: Squirrels can wreak havoc in gardens, feeding on fruits, vegetables, and digging up plants. Their digging can be particularly frustrating for gardeners.
- Bird Feeder Destruction: Bird feeders are often targeted by squirrels. Their persistence and strength allow them to break into feeders to access bird seeds, leading to spillage and feeder damage.
- Property Damage: Squirrels’ gnawing habits extend indoors, where they can damage furniture and structures. Chewing on electrical wiring is a serious concern, posing fire hazards and requiring costly repairs.
Furthermore, squirrels can carry and transmit diseases, though these are relatively rare in humans. Diseases associated with squirrels include:
- Tularemia: This bacterial disease can be transmitted through bites or direct contact with infected squirrels. Symptoms include fever, headaches, swollen lymph nodes, and skin ulcers.
- Leptospirosis: Similar to rats, squirrels can carry leptospirosis, which is transmitted through contact with infected urine, particularly through open wounds. Symptoms include fever, headache, rashes, and vomiting.
- Parasite-borne Diseases: Squirrels can host parasites like ticks and fleas, which can transmit diseases such as Lyme disease and Rocky Mountain spotted fever to humans.
How to Keep Squirrels and Rats Away: Prevention Strategies
Given the potential for both squirrels and rats to cause damage and pose health risks, implementing preventative measures is crucial. Effective methods to deter both include:
- Rodent-Proofing Your Home: Seal potential entry points. Trim tree limbs and plants near doors and windows, as these can provide access routes. Seal cracks and holes, even small ones (rats can squeeze through openings as small as half an inch), using caulk and steel wool or other solid materials like concrete, metal, glass, or hard plastic. For larger openings, consider using sheet metal for ventilation while blocking rodents.
- Trapping: Trapping can be an effective way to remove rodents already on your property. Snap traps, glue boards, and electronic traps are options. Use enticing bait like nuts, seeds, or fruits. Always wear gloves when handling bait and set multiple traps for better results.
- Using Strong Odors as Repellents: Strong scents can deter rodents. Kitchen ingredients like onions, pepper, and garlic have pungent smells that can repel squirrels and rats. Peppermint oil is another effective repellent. Soak cotton balls in peppermint oil and place them around your home or create a peppermint oil spray by diluting it in water.
- Commercial Rodent Repellents: Electronic rodent repellents emit ultrasonic sounds irritating to rodents (inaudible to humans). Chemical repellents are also available, but use them cautiously, following manufacturer instructions to avoid accidents.
- Making Your Home Unattractive: Eliminate food and water sources. Store food in airtight containers (glass jars or sealed plastic). Avoid leaving food or water bowls out. Clean up spilled bird seeds from bird feeders or invest in rodent-proof feeders. Reduce clutter, as it provides nesting areas. Store belongings in heavy-duty plastic containers instead of cardboard boxes.
