Rodents
Rodentia (Order)
Mice and rats are common household pests. They ruin food, spread germs, chew through wires, and breed fast. If you spot signs of rodents, getting help quickly is key.
Rodent Identification Guide
Physical Characteristics
Rodents are mammals with large front teeth that never stop growing. This is why they gnaw on things all the time. Mice are small. They are about 2 to 4 inches long with big ears and thin tails. Rats are much larger. They can reach 7 to 10 inches in body length. Rats have thicker tails and smaller ears for their size.
Common Species
-
House Mice: Small, grayish brown rodents with large ears and pointed snouts. They are the most common indoor rodent pest.
-
Norway Rats: Large, brown rats that dig burrows near foundations. They often enter through basements. Some people call them sewer rats.
-
Roof Rats: Slender, dark colored rats that are great climbers. They often enter through upper floors and rooflines.
Rodent Behavior and Biology
Rodents are active at night. They prefer to travel along walls and edges. They fear new things, which can make trapping harder. Mice are curious and quick to check out new objects. Rats are more careful. They take longer to approach traps. Both can breed all year indoors. They will gnaw through almost anything. This includes wood, plastic, and even concrete.
How We Treat for Rodents
We use a simple approach that combines removal with prevention.
Initial Treatment: We start with a full inspection. We find entry points, nesting areas, and travel routes. Then we set up traps in key spots and track activity. For heavy outdoor problems, we may use bait stations.
Exclusion: We seal entry points with materials that rodents cannot chew through. This includes steel wool, hardware cloth, and sealants. This step is the most important. Without it, new rodents will just take the place of those we remove.
Ongoing Monitoring: We return for follow up visits to check traps and look at activity levels. We make sure exclusion work holds up. Our maintenance plans give you protection all year.
Health Risks
Rodents can spread diseases. They pass germs through their droppings, urine, and saliva. Their gnawing on wires can also cause fire hazards. If you think you have been exposed to illness from rodents, please talk to a doctor for medical advice.

Deer Mouse
Peromyscus maniculatus
Deer mice are small, native North American rodents known for their bicolored fur and white underbellies. While they typically live outdoors in fields and forests, they frequently enter homes seeking warmth during fall and winter, posing health concerns as carriers of hantavirus.

Field Mouse
Peromyscus maniculatus
Field mice, also known as deer mice, are small rodents found throughout North America. Distinguished by their two-toned coloring and large eyes, they are primarily outdoor pests but may enter homes seeking shelter, particularly during colder months.

Mice
Mus musculus
House mice are small rodents that commonly invade homes seeking food, water, and shelter. Known for their rapid reproduction and ability to squeeze through tiny gaps, mice can quickly become a serious infestation.

Rats
Rattus norvegicus
Rats are common household pests that can cause significant structural damage and spread disease. The Norway rat is the most prevalent species in the United States, known for burrowing near foundations and invading basements.

Roof Rat
Rattus rattus
Roof rats are agile climbers that prefer elevated spaces like attics, ceilings, and upper levels of buildings. Also known as black rats or ship rats, they are smaller and sleeker than Norway rats and pose significant health and property risks.

How do I know if I have mice or rats?
+
Look for droppings, gnaw marks on food or structures, scratching sounds in walls at night, grease marks along baseboards, and nesting materials like shredded paper. Mouse droppings look like grains of rice while rat droppings are larger.
Are rodents dangerous?
+
Yes, rodents pose real health risks. They can spread diseases through their droppings, urine, and saliva. They also gnaw on electrical wiring, which can create fire hazards. They can cause damage to your home's structure too.
How do mice get in my house?
+
Mice can squeeze through gaps as small as a dime. Common entry points include gaps around pipes, utility lines, doors, windows, and foundation cracks. They also enter through garage doors, vents, and roof lines.
Will one mouse turn into an infestation?
+
Most likely, yes. Mice rarely travel alone and can breed fast. Females can have 5 to 10 litters per year with 5 to 6 pups each. By the time you see one mouse, there are usually more hiding nearby.
Do ultrasonic repellers work on rodents?
+
Studies show ultrasonic devices do not work well. Rodents may avoid the sound at first but get used to it quickly. Professional exclusion and trapping are much more reliable.
How long does rodent control take?
+
Trapping usually cuts activity within 1 to 2 weeks. Full removal and exclusion may take 2 to 4 weeks based on how bad the problem is. Ongoing checks help make sure they do not return.
