As the seasons change in Missouri, so does the behavior of some of the state’s more elusive residents—rodents. Mice, rats, and other pests become particularly active in searching for food, shelter, and warmth as the weather cools. Whether you live in a rural area or the heart of a city, rodent infestations can cause significant problems in Missouri homes. Understanding how to prevent, identify, and control rodent activity is essential for keeping your home safe and free of these unwanted guests.
The most common rodents found in Missouri homes include house mice, Norway rats, and roof rats. These pests can quickly make themselves at home, gnawing on wood, wires, and plastic, leading to severe property damage. In addition to physical damage, rodents can carry diseases like hantavirus and salmonella, making it essential to address infestations promptly.
House Mice: Small, agile, and prolific breeders, house mice are notorious for invading homes through even the tiniest cracks. Once inside, they multiply rapidly, often nesting in walls or behind appliances.
Norway Rats: These larger rodents are often found in basements and crawl spaces. They tend to burrow under foundations and can cause structural damage to homes.
Roof Rats: Skilled climbers, roof rats often enter homes through attics or roofs and can chew through insulation and wiring.
Rodents may be small, but the damage they can cause to both your home and your health is significant. Here’s what you need to know about the risks of a rodent infestation:
Structural Damage: Rodents have strong teeth that never stop growing, which means they gnaw constantly. They can chew through wood, drywall, and even concrete, leading to damage in walls, floors, and foundations. Over time, this can weaken the structural integrity of your home, causing costly repairs.
Electrical Hazards: One of the most dangerous forms of damage caused by rodents is to your home’s electrical system. Rodents frequently chew on wires, which can strip the insulation and expose live electrical wires. This can create a serious fire hazard, with wiring shorts leading to potential electrical fires within the walls of your home.
Insulation Destruction: Mice and rats often nest in attics and walls, where they can damage insulation by shredding it to create nests. This can lead to reduced energy efficiency, causing your heating and cooling bills to spike.
Water Damage: Rodents are also known to chew through pipes or gnaw on materials around plumbing. This can cause leaks, which, if left unchecked, can lead to mold growth or structural water damage.
Health Hazards: Rodents carry a variety of diseases that can be harmful to humans. Their droppings and urine can contaminate surfaces, leading to the spread of illnesses like hantavirus, leptospirosis, and salmonella. Additionally, they can introduce fleas, ticks, and mites into your home, affecting people and pets.
Food Contamination: If rodents access food storage areas, they can contaminate food with their droppings and urine. This can result in foodborne illnesses and costly waste if food supplies need to be discarded.
Rodents are nocturnal and tend to stay out of sight, making them difficult to detect. However, there are several telltale signs of an infestation:
Droppings: Rodent droppings are often found in areas where food is stored, such as pantries or cupboards.
Gnaw Marks: Mice and rats will chew on wood, plastic, wires, and even food packaging.
Nesting Materials: Rodents create nests using materials like paper, fabric, or insulation. Look for small piles of shredded material in secluded areas.
Scratching Noises: If you hear scratching or scurrying in the walls or ceilings, you may have a rodent problem.
The best way to avoid the hassle of a rodent infestation is through prevention. One of the most critical steps is sealing entry points to keep rodents from getting inside in the first place. Here’s how to effectively rodent-proof your home by identifying and sealing common entry points:
How to Seal Entry Points and Prevent Rodent Access
Rodents can squeeze through incredibly small openings, so thoroughly inspecting your home and sealing potential entry points is vital to keeping them out. Below are the most common areas where rodents can enter your home and how to properly seal them:
Foundation Cracks and Gaps: Check your home’s foundation for any cracks or holes. Rodents can fit through holes as small as a dime. Seal these gaps using concrete, caulk, or steel wool combined with caulk.
Doors and Windows: Inspect all exterior doors and windows. Gaps underneath doors or around window frames are easy entry points for rodents. Install weatherstripping or door sweeps to close these gaps. Ensure window screens are intact and free of tears, and check for gaps between the window frame and the building structure.
Roof Vents and Chimneys: Roof rats are skilled climbers and often enter homes through vents, chimneys, or gaps around roofing materials. Install metal mesh or screening over roof vents, and ensure your chimney has a cap to block rodents from getting inside.
Attic and Roofline: Rodents can enter through small gaps or holes in the roof or eaves. Inspect your attic and roofline for any gaps and seal them with caulk, wire mesh, or hardware cloth. Pay special attention to areas where the roof meets the walls and ensure that soffit vents are properly sealed with screening.
Basements and Crawl Spaces: Basements, especially older ones, can have cracks in the walls, foundation, or around windows that rodents can exploit. Seal these areas with mortar or foam insulation. Crawl space vents should also be covered with metal mesh to prevent access.
Garage Doors: Rodents can easily slip under garage doors if the weatherstripping is worn or damaged. Replace the weatherstripping and check that the door closes tightly against the ground. Also, look for gaps along the sides of the garage door and install door seals if necessary.
Plumbing and Utility Openings: Rodents often enter homes through openings around pipes, cables, or wiring that enter the home from the outside. Seal around these areas with expanding foam, caulk, or metal mesh to block entry.
If you suspect a rodent infestation, acting quickly is important to prevent it from worsening. Poisons can pose risks to pets and children, and may leave decaying rodents hidden in your walls. Instead, use live traps or consult with a pest control professional.
Rodents in Missouri pose risks to both your home and your health. Taking preventive steps, such as sealing entry points, helps safeguard your property and keep your family safe.
