Discovering rats or mice in your Pennsylvania home or business is a problem that deserves prompt attention. Rodents can threaten the health of your family, employees, and customers while chewing through materials and damaging your property. Businesses may face additional challenges, as visible rodent activity can negatively affect their reputation and customer relationships.
Seitz Bros. offers professional rodent control services to help homeowners and business owners address rodent problems. Our experienced technicians have the training needed to apply appropriate removal methods and help keep rodents from disrupting your property.
What Are the Signs of a Rodent Infestation?
Rats and mice often leave behind clues that can help you identify a potential infestation. Keep an eye out for the following warning signs:
- Rodent Droppings: Look for small, brown droppings shaped like grains of rice.
- Gnaw Marks: Because rodents’ teeth grow continuously, they regularly chew on different materials. Bite marks on wood, packaging, and other objects may indicate a rodent problem.
- Nests: Rodents often create nests in hidden corners, storage areas, and other undisturbed spaces.
- Scratching Sounds: Noises coming from inside walls or above the ceiling at night can be a sign of rodent activity.
- Rub Marks: Greasy, shiny marks on walls, baseboards, and other surfaces may develop where rats and mice repeatedly pass.

Identifying Common Types of Rodents
Mice and rats can enter Pennsylvania homes and businesses in search of food, water, and shelter. Different species have distinct characteristics, nesting habits, and potential health risks.
Learning to recognize the following common types of mice and rats can help you identify rodent activity and understand the problems they may cause:
Mice
Several types of mice can find their way into Pennsylvania homes and businesses. Learning about the characteristics and habits of these common species can help you recognize which rodents may be sharing your property.
- Deer Mouse: Deer mice have small bodies that average about two inches long and often enter buildings in wooded areas. They are known carriers of hantaviruses that can cause Hantavirus Pulmonary Syndrome, a potentially fatal respiratory illness.
- House Mouse: House mice have bodies approximately two inches long and can squeeze through small openings to enter buildings. They live in urban and suburban areas and frequently seek shelter indoors during fall and winter when outdoor food sources become scarce.
- White-Footed Mouse: White-footed mice typically live outdoors, nesting in stacked wood, beneath tree limbs, or inside tree cavities. When they enter buildings, they tend to hide in quiet spaces such as crawl spaces, basements, and attics. These mice can carry blacklegged ticks, which may transmit Lyme disease.
Although these species have different habits, all three can become unwelcome visitors inside your property. Identifying the type of mouse you’re dealing with can help determine the appropriate approach to rodent control.
Rats
Not all rats behave alike, and knowing which type has entered your property can help you understand where it may be nesting. In Pennsylvania, three types to be aware of are Norway rats, pack rats, and roof rats.
- Norway Rat: Norway rats are large rodents that tend to establish nests in lower areas, including basements and spaces close to the ground. They often move indoors when outdoor resources are limited or when they find convenient access to food and water.
- Pack Rat: Pack rats are recognized for gathering and storing a variety of materials near their nests. They may take shelter in secluded locations and can become problematic when they enter homes or other buildings.
- Roof Rat: Roof rats are skilled climbers that commonly nest in trees, attics, ceilings, and other elevated spaces. They may enter buildings through openings around roofs and upper levels while looking for resources.
All three types can create concerns for property owners. In addition to gnawing on materials and contaminating food, rats may carry organisms that cause diseases such as salmonellosis, leptospirosis, and trichinosis.

Commercial Rat and Mouse Control
Rats and mice can cause more than property damage when they enter commercial buildings. For restaurants, stores, and other businesses in Pennsylvania, visible rodent activity can raise concerns about cleanliness and discourage customers from returning. Even a single sighting in a customer-facing area or workplace can negatively affect your reputation.
Since rodents frequently remain hidden, spotting one may mean others are nearby. Seitz Bros. provides professional commercial rodent control throughout Pennsylvania, helping businesses address infestations and limit the impact on their facilities, employees, and customers.
