Knowing you have a rodent infestation, but not understanding what kind of rodents are haunting your home, is more common than you might think. As exterminators serving St. Paul, Minnesota, we're often called when homeowners know they have rodents but aren't sure which ones, how they got in, or when they arrived.
From years of providing professional rodent control, we've learned that rodent behavior changes with the seasons. Understanding when rodents enter your home is one of the most reliable ways to identify what infestation you're dealing with.
Fall: When Rodents Begin Looking for Shelter
Rodent activity spikes in the fall. As temperatures drop and cold weather approaches, rodents begin searching for warm places to nest.
Mice in the Fall
Fall is the peak entry season for mice.
- Mice begin scouting homes for warmth and food
- They enter through small gaps and holes in exterior walls
- Early nests form in wall cavities, basements, and storage areas
Many winter mouse problems actually begin in the fall before homeowners realize there's an issue.
Rats in the Fall
- Rats become more visible near garbage cans and food sources
- They start moving closer to structures for shelter
- Entry points near foundations and sewer lines become more active
Fall infestations often go unnoticed until winter arrives and rodents are fully settled inside.
Winter: Peak Rodent Infestation Season in Minnesota
Winter is the busiest time of year for rodent control in St. Paul. Once rodents get inside, they don't leave.
Mice in the Winter
Mice remain active indoors throughout the winter months
- Scratching noises in walls and ceilings are common, especially at night
- Droppings are often found near kitchens, pet food, and pantries
- Nesting continues inside insulation and other soft materials
Once mice are inside for winter, infestations can grow quickly without proper control.
Rats in the Winter
- Rats rely heavily on indoor food sources during cold weather
- Activity increases in basements, crawl spaces, and lower levels
- Larger droppings, gnaw marks, and strong odors are common signs
Winter rat infestations often require immediate rodent removal service due to the amount of damage rats can cause.
Spring: Breeding Season and Hidden Infestations
Spring brings increased movement and breeding activity. From an exterminator's perspective, this is when small problems can turn into full-blown infestations.
Mice in the Spring
- Mice begin breeding heavily
- Activity increases as mice move between indoor and outdoor spaces
Spring infestations are often the result of rodents that overwintered inside the home.
Ground Rodents in the Spring
- Voles and other ground rodents become active as snow melts
- Activity is usually noticed outside near foundations and landscaping
- Their burrowing can create entry points for other rodents
Summer: Rodents Move, But Don't Leave
Rodent calls slow down in summer, but rodents are still present, just in different areas.
Mice in the Summer
- Mice move between garages, sheds, and homes
- They feed on pet food, bird seed, and accessible food sources
- Nests are often found in less-used spaces like storage areas
Squirrels in the Summer
- Squirrels are most active in summer and early fall
- They commonly enter attics and rooflines
- Daytime activity and loud movement are key indicators
Squirrels are frequently mistaken for rodents, but they require a different approach than standard rodent control.
