Why Rodent Pressure Often Rises as Fall Arrives

The Early-Fall Window for Finding Entry Points

As summer ends and the temperatures begin to drop, residents of Charles City should begin to inspect their properties for areas where mice and rats can enter. The cooler months drive rodents indoors as they seek access to food, shelter, and areas to nest. The areas within wall voids allow easy access to insulation for nests, pathways to food within cabinets, and areas out of reach. 

The fall season is an important transitional period as rodents will begin to seek areas around homes, garages, and outdoor sheds to gain access to. Rooflines in particular can become easily overlooked, but rodents can use treelines and branches in order to access rooftop and attic spaces. Fall foliage, brush, and backyard firewood can also lead to increased areas where rodents can hide within outdoor living spaces as they seek entry into homes through ground level openings. Charles City residents should clear out brush and leaf litter, and inspect foundational areas, external pipes, utility lines, and other common areas around the home where small gaps and cracks can provide easy entry. Inside homes, look for signs of early rodent activity. This can include droppings, chew marks on food, gaps within baseboard areas, or scratching sounds from within wall voids.

What to Do Before the First Cold Spells

There are proactive steps that Charles City residents can take before the temperature drops. The most effective way to create a barrier around your home is to begin from the perimeter and work your way towards your home. Reduce leaf litter, brush, and firewood from areas around foundations, sheds, or porches where rodents can nest and hide. Regularly clear your outdoor living areas of food, seed, and fruit from trees. These food sources will attract rodents to your home, ultimately creating an easier pathway into your indoor living areas. Keep bird and animal feed in secure containers that are tightly sealed and located at least a few inches from the ground or walls. 

Because mice can squeeze through a hole the size of ¼ inch, it’s important for Charles City residents to seal and reduce points of entry. Conduct an inspection of your property and use a flashlight to help you notice small gaps and cracks that can become hidden due to shade or shadows. Ensure that door sweeps and screens are replaced, seal gaps around external pipes, and check vents for areas where rodents can enter. When sealing gaps around your property, use durable sealants that limit and reduce the ability for rodents to chew through the material.

When Seasonal Rodent Pressure Becomes an Indoor Problem

Even with the preventative efforts of Charles City residents, seasonal changes can still lead to increased pest pressure within homes. As the temperature drops, mice will enter indoor areas in search of food, shelter, and areas to nest over the winter. This can lead to destroyed insulation, rodent droppings on counters, and even electrical damage. If you’re noticing the signs of rodent activity, it could be time to consider professional rodent control services.
