Health Risks & Damage
Rodents aren’t just a nuisance; they pose serious health and safety risks in the home.
Seasonal Rodent Behavior
Rodents are active year-round, but their behavior changes with the seasons, often driving them closer to or inside your home.
In spring and summer, rodents like roof rats and house mice take advantage of warmer weather to breed and expand their territory. You might spot them foraging outside or nesting in sheds, garages, or attics with easy access to food and shelter.
As fall approaches, rodents begin preparing for colder weather. This is when Norway rats and deer mice often invade homes, garages, and crawl spaces seeking warmth, nesting material, and a steady food source. These months mark the peak of rodent break-ins as they follow pipes, wiring, or foundation cracks indoors.
During winter, rodents typically remain hidden but active inside structures, nesting behind walls, in attics, or beneath appliances. Without professional intervention, indoor populations can explode, leading to property damage and health concerns by the time spring returns.
Insight Tip: Don’t wait for cold weather to uncover a rodent issue. Fall exclusion and inspection services are key to keeping them out before they make themselves at home.
