About Rodents
Rodents are a diverse and highly adaptable group of mammals, making up about 40% of all mammal species. This equates to around 1,500 different types of animals, including well-known species such as rats, mice, beavers, porcupines, squirrels, guinea pigs, gophers, and hamsters. Their remarkable adaptability allows them to thrive in a wide range of environments, from urban cities and suburban homes to forests, grasslands, and wetlands.
Rodents have been an integral part of various ecosystems for millions of years, playing crucial roles in seed dispersion, soil aeration, and as a food source for many predators. Their ability to reproduce rapidly and their keen survival instincts have enabled them to become one of the most widespread groups of mammals on the planet. Despite their often negative reputation, especially in urban settings where they are considered pests, rodents are fascinating creatures with complex behaviors and social structures. Understanding their biology and behavior is essential for both appreciating their ecological significance and managing their presence in human habitats.
What do rodents look like?
Rodents vary greatly in size, ranging from a few inches to several feet and from one ounce to 150 pounds, depending on the species. Despite their size differences, all rodents share the characteristic of having sharp, curved incisors that never stop growing. To prevent their teeth from becoming too long, rodents must constantly gnaw on objects to wear them down. Remarkably, rats and mice can deliver up to six bites per second and have the ability to gnaw through materials as tough as concrete and metal.
In addition to their teeth, rodents have highly developed senses of vision, smell, and hearing. Many rodents also possess whiskers, which they use to enhance their tactile sense, helping them navigate their surroundings.
Common rodents such as rats and mice have a maximum lifespan of about five years, while species like marmots, chinchillas, and chipmunks can live between 10 to 15 years. A single mouse can produce over 50 offspring annually and can become pregnant again just 24 hours after giving birth.
Unique characteristics of rodents
Rodents exhibit a wide range of traits depending on their type, locale, and size. Most rodents are excellent swimmers; for instance, rats can tread water for up to three days. They are also adept jumpers, climbers, and burrowers. Mice, with their flexible bodies, can squeeze through holes as small as a dime.
Rodents are known for their intelligence. Rats can be trained to perform tricks, and mice have an impressive memory for paths they have previously taken. This cognitive ability helps them navigate complex environments and avoid predators.
Habits of rodents
Rodents exhibit diverse dietary habits. They can be herbivores (eating plant-based diets), predators (seeking out insects and other small animals), or omnivores (eating almost anything). Common rodents like rats and mice will consume paper, wiring, drywall, wood, and human and pet food.
Rodents can be active both day and night. Rats and mice are generally nocturnal, preferring to avoid humans, while squirrels are diurnal and active during the day.
Where are rodents commonly found?
Rodents inhabit a variety of environments. Outdoors, they can live in underground burrows, trees, crevices between rocks, and dense vegetation. Indoors, they often take up residence in homes and other structures, seeking warmth and shelter. As mammals, rodents need warmth, especially when temperatures drop.
Risks of a rodent infestation
Non-domesticated rodents pose significant risks to people and pets. They can transmit at least 35 diseases, including Lyme disease, salmonella, leptospirosis, hantavirus, and rat-bite fever. Rodents can also cause substantial property damage by gnawing on structures, wiring, and insulation. Additionally, if provoked, rodents may attack animals and humans.
DIY methods of rodent control
Do-it-yourself baits and traps may attract rodent intruders. However, if not properly administered, they can also be harmful to people and pets. A pest control professional can evaluate your property to determine how to best prevent and treat pesky rodents.

Rodent Prevention
Rodents are most harmful when they infiltrate homes. To prevent a rodent infestation, consider the following measures:
- Block potential entry and exit points: Seal cracks, holes, and other openings in walls, floors, and foundations to prevent rodents from entering your home.
- Keep your home and its surroundings clean: Regularly clean up food crumbs, spills, and other debris that might attract rodents.
- Store food in airtight containers: Prevent rodents from accessing food by storing it in sealed containers.
- Remove clutter and debris: Eliminate potential hiding places for rodents by keeping your living areas and storage spaces tidy.
- Prune trees and shrubs away from your home: Trim back vegetation that might provide rodents with easy access to your home.
By implementing these preventative measures, you can significantly reduce the risk of a rodent infestation and keep your home safe and rodent-free.
