3. They’re Seeking Shelter
Mice and rats usually live outside before coming inside a home or structure. They’re often either drawn in by the possibility of food and shelter or forced in by changing seasons and weather patterns. Certain kinds of rodents may infest wood piles and brush, so if those sources of outdoor refuse or firewood are close to your home or business and set directly against the ground, the chances that a rodent will make its way inside will increase. If you allow trees to grow too close to your roof, rodents like roof rats can easily find their way into your attic or rafters.
Mice and rats can also fit through tiny gaps in walls and will chew away at these openings, crevices, or wall cavities in order to fit through. This makes them even more of a nuisance because their persistence at getting where they want to go on your property can make preventing an infestation difficult.
Common Times for Infestations
While rodents will infest your home at any point during the year, you’re especially likely to notice an infestation during the winter as they seek shelter from the cold. Rodents are even known to infest vehicle engines because of their warmth, and because a hungry rodent will even eat wire insulation.
In addition, if a house or business is left vacant for extended periods of time, it’s more likely that a rodent or two will set up camp. If you’ve recently bought a home or business, it’s a good idea to find out from your realtor if the property has been unoccupied between closing and your move-in date.
