Do you believe rodents might be on your property? These pests can cause all kinds of issues. As well as being associated with disease, they can also chew through wiring and cause other structural issues. Learn everything you need to know.

What Are Rodents?

Rodents are a diverse group of mammals that belong to the order Rodentia. They make up the largest order of mammals, comprising over 40% of all mammal species. Rodents are characterized by a set of dental features that include continuously growing incisors (front teeth) that must be constantly worn down through gnawing and chewing.

Key characteristics of rodents include:


Rodents have a pair of long, sharp, and continuously growing incisors in their upper and lower jaws. These incisors are used for various tasks, including cutting through vegetation, digging, and gnawing on objects.

Gnawing Behavior

Due to their ever-growing incisors, rodents have a strong need to gnaw and chew on objects to prevent their teeth from becoming too long. This behavior helps keep their teeth at a manageable length.

Herbivorous Diet

Most rodents are herbivores, primarily feeding on plants, seeds, nuts, fruits, and other vegetation. However, some species are omnivorous or carnivorous.

Diverse Species

The rodent order includes a wide range of species, from tiny mice and voles to larger animals like squirrels, beavers, porcupines, and capybaras. Some well-known rodents also include rats and guinea pigs.

Worldwide Distribution

Rodents are found on every continent except Antarctica, and they inhabit a variety of ecosystems, from forests and grasslands to urban areas.


Rodents typically have high reproductive rates, with many species producing multiple litters of offspring each year. This contributes to their ability to thrive in various environments.


Rodents are known for their adaptability and ability to exploit diverse ecological niches. They have evolved to live in a wide range of habitats and climates.

While some rodent species are considered pests due to their ability to damage crops and structures, others serve important ecological roles as seed dispersers, prey for predators, and ecosystem engineers (e.g., beavers building dams).

Despite their sometimes-negative reputation, rodents are a crucial and diverse group of mammals with significant ecological and economic importance.

Are Rodents Dangerous?

Whether rodents are considered dangerous or not depends on various factors, including the specific species, their behavior, and their interactions with humans and the environment. Here are some considerations:

Disease Transmission

Some rodents can carry and transmit diseases to humans and other animals. For example, rodents like rats and mice can carry diseases such as hantavirus, leptospirosis, and salmonellosis. These diseases can pose health risks when rodents infest homes or contaminate food and water sources.

Crop and Property Damage

Certain rodents, such as rats and groundhogs, can cause significant damage to crops, gardens, and property. They may eat or destroy crops, chew through structures, and create burrows that undermine foundations.

Contaminating Food and Resources

Rodents can contaminate food storage areas and resources with their urine, droppings, and fur. This contamination can lead to foodborne illnesses and economic losses.

Ecological Impact

In some cases, rodents can have negative ecological impacts. For example, invasive rodents introduced to new environments can disrupt native ecosystems by outcompeting or preying on local species.

Nuisance Behavior

Rodents that invade homes or businesses can be considered a nuisance due to their gnawing, nesting, and noise-making activities. Their presence can be stressful and may lead to property damage.

Predation and Competition

Rodents are an important food source for many predators in the wild. They are also competitors with other herbivorous species for resources like food and shelter.

It's important to note that not all rodent species are dangerous or harmful. Many rodents play essential roles in ecosystems, such as seed dispersal, and are not a direct threat to human health or property.

Additionally, some rodents, like guinea pigs and hamsters, are kept as pets and are not typically considered dangerous.

To mitigate the potential dangers associated with rodents, it's important to practice effective pest control measures, maintain proper sanitation, and take steps to prevent rodent infestations in and around homes and businesses.

If you suspect a rodent infestation or have concerns about rodent-related issues, it is advisable to seek the assistance of pest control professionals.

Why Do I Have a Rodent Problem?

Rodent problems can arise for various reasons, and understanding the underlying causes can help you take appropriate steps to prevent or address the issue. Here are some common reasons why you might have a rodent problem:

Food Availability

Rodents are attracted to easily accessible sources of food. If you leave food crumbs or improperly stored food items in your home, it can attract rodents like rats and mice. Make sure to store food in sealed containers and clean up food spills promptly.

Shelter and Nesting Sites

Rodents seek shelter and suitable nesting sites. Your home or property may provide attractive hiding places, such as cluttered basements, attics, crawl spaces, or areas with plenty of nesting materials like cardboard, paper, or fabrics.

Water Sources

Like all animals, rodents need water to survive. Leaky pipes, standing water, or uncovered water sources can attract them. Fixing leaks and removing standing water can help make your property less appealing to rodents.

Outdoor Conditions

Your property's outdoor conditions can also contribute to a rodent problem. Overgrown vegetation, bushes, or cluttered outdoor areas can create ideal hiding spots for rodents. Keeping your yard well-maintained can reduce their access to shelter.

Gaps and Entry Points

Rodents can enter buildings through small cracks, gaps, or holes in walls, foundations, roofs, and doors. Inspect your home for potential entry points, and seal them with appropriate materials, such as steel wool, caulk, or hardware cloth.

What Are Signs of a Rodent Invasion?

Detecting the signs of a rodent invasion early is crucial for effective pest control. Here are common signs that may indicate you have a rodent problem:


Rodent droppings are a clear sign of their presence. Mouse droppings are small, about the size of a grain of rice, while rat droppings are larger, about the size of a raisin. The color and shape may vary depending on the species.

Gnaw Marks

Rodents have continuously growing incisors and often leave gnaw marks on various objects, such as wood, plastic, wires, and food packaging. Look for chewed or damaged items.

Urine Odor

The presence of rodents can be associated with a strong, ammonia-like odor from their urine. You may notice this smell in confined spaces like attics, crawl spaces, or basements.

Nesting Materials

Rodents use materials like paper, fabric, and plant matter to build nests. Finding shredded materials in hidden areas of your home, such as behind walls or in insulation, could indicate a nesting site.

Scratching Noises

Rodents are active primarily at night. If you hear scratching or scurrying sounds in walls, ceilings, or other hidden spaces, it may suggest a rodent infestation.

Grease Marks

As rodents travel along walls and baseboards, they often leave greasy smudges or tracks from the oils on their fur. These marks may appear as dark streaks.

Burrows and Holes

Check for burrows or holes in your yard, garden, or around your property. Rodents like rats and groundhogs often create burrows for shelter.

Tracks and Footprints

In dusty or muddy areas, you may find rodent tracks or footprints. These can help identify the type of rodent present.

Missing or Damaged Food

Rodents are known to raid pantries and food storage areas. If you find evidence of gnawed food containers or missing food items, it's a sign of their presence.

Pet Behavior

Cats and dogs may exhibit unusual behavior if they detect the presence of rodents. They may spend more time investigating certain areas or become more alert and agitated.


Occasionally, you may see rodents during the day, especially if the infestation is severe. Mice and rats tend to avoid humans and are more active at night, so daytime sightings can be a significant concern.

Droppings and Odor in Pet Areas

If you have pets, check their living areas for rodent droppings or unusual odors, as rodents may be attracted to pet food.

If you notice any of these signs, it's essential to take action promptly to address the rodent problem. Ignoring the issue can lead to more significant infestations and potential health risks. Consider contacting a pest control professional for an inspection and assistance with rodent removal and prevention.
