Risks and Damage Caused by Mice

Health Risks

Mice can transmit over 55 diseases, including salmonella, and are the primary carriers of Lyme disease. They can also trigger allergies and asthma, particularly in children, according to Johns Hopkins research.

Parasite Hosts

Mice often bring pests like ticks, fleas, and mites into homes, further increasing health risks.

Fire Hazards and Property Damage

Mice cause significant damage by gnawing on wires, insulation, and wood, leading to electrical problems and fire hazards, responsible for 25% of “unknown fires” as estimated by the EPA.

Don’t let small problems turn into big ones.

Frequently Asked Questions about Mice

Identifying Mice in Your Home

Several signs can indicate mice infestations, such as:

  • Droppings: Mice leave small, dark droppings wherever they travel but especially in their nesting and feeding areas.
  • Gnawed or Damaged Items: Mice have strong teeth and gnaw on various materials to keep them sharp. Look for gnaw marks on food packaging, wires, and even furniture.
  • Nesting Materials: Mice build nests using soft materials such as shredded paper, fabric, and insulation.
  • Scratching or Scurrying Noises: If you hear scratching or scurrying noises in walls or ceilings, it could be a sign of mice moving around.

Mouse droppings vary, depending on the species. House mice produce small to medium-sized droppings that are typically dark in color and have a rod-like shape with pointed ends. White-footed mice, a.k.a field mice, produce medium-sized droppings that are lighter in color and have a more cylindrical shape.

If you see any droppings, it’s best to contact a pest control professional for proper identification and treatment.

The average mouse infestation size is approximately 6, varying due to factors such as mouse species, how quickly they breed, and available food sources.

Since mice are so small, they can fit through spaces as small as 1/4 inch, including:

  • Chimneys
  • Utility holes/hookups to the house, especially where hot air and/or smells are coming from (and once they find it, others will follow)
  • Gaps around the foundation
  • Windows
  • Under driveway
  • Gaps and holes around utilities, doors, windows, foundation, and vents
  • Obscure location gaps with rebar below exterior slabs and gaps around the roof especially with trees and scrubs near the house
  • Shared walls between attached homes

Still wondering how those mice snuck in? Our blog How Do Mice Get in Your House? reveals additional entry points and winter-specific considerations to help you tighten up your defenses.

Mice infest homes looking for:

  • Food
  • Shelter
  • Water

Treating Rodent Infestations

Here’s how to get rid of newly introduced mice in your house quickly:

  • Set snap traps in strategic locations where they are likely to travel, such as along walls and near food sources.
  • Eliminate all potential food sources.
  • Seal off all possible entry points with weather stripping, door sweeps, and metal screens.
  • Call Brody Brothers for professional mice pest removal.

Considering DIY pest control for mice? Discover why mouse traps alone might not work and explore alternative approaches.

A mouse exterminator will typically use a combination of methods including identifying and sealing off entry points, setting devices, and using bait products to remove mice from your home. They can also provide long-term solutions to prevent mice from returning.

Prevent Mice Infestations

Preventing mice from entering a property is the best way to infestations. Some preventative measures to keep mice out of your house include:

  • Seal all potential entry points to your home.
  • Store food in sealed containers, especially pet food.
  • Regularly clean and sanitize the kitchen and dining areas.
  • Seal cracks and holes in the building’s foundation and walls.
  • Clean up crumbs and spills regularly.
  • Avoid storing items in cardboard.

Here’s how to keep mice out of your yard and maintain a pest-free outdoor space:

  • Keep trees and shrubs trimmed away from the building.
  • Store firewood away from the building.
  • Keep garbage cans tightly closed and away from the building.
  • Regularly inspect and maintain outdoor structures such as sheds and garages for cracks or openings that may serve as entry points for mice.
  • Remove clutter and debris from the yard that can shelter mice.
  • Clean up or remove birdseed feeders

Mice like to hide in dark, secluded places, such as:

  • Stoves
  • Wall voids
  • Under or behind kitchen equipment
  • Under cabinets and kickplates
  • Ceilings/ceiling voids
  • Equipment
  • Vents
  • Attics
  • Garages
  • Basements

It’s important to note that since they are most comfortable in corners or hidden and secluded spots, typically where you first spot the rodents isn’t where it actually lives in your home.

Some of the most popular places you’ll find mice in your yard are:

  • In debris such as logs piles
  • Sheds
  • Near exterior trash cans
  • In short ground cover, such as ivy
  • In yard equipment
  • Inside outdoor grills
  • Car engines

Problems with Mice

House mice are some of the most difficult pests to control. This is due to several factors, such as:

  1. They’re rapid breeders: A pair of mice can easily outpace most mouse traps and bait stations.
  2. They’re nocturnal and secretive: They’re active at night and nest in hidden areas, making them hard to target.
  3. They have different preferences and behaviors: Some mice readily eat bait products, while others avoid new things, requiring various approaches.
  4. Their range is small: House mice’ home range is only 4-6 feet, so baits placed outside of their home range are unlikely to be found.
  5. They’re nibblers: Mice take tiny amounts of food at a time — about the size of a grain of sand — which means the bait needs to be fresh and high-quality bait to be most effective.
  6. They’re excellent climbers: Mice can crawl up many surfaces, such as vinyl, cement, bricks, wires, vines, counters, and pipes – giving them lots of ways to invade your Baltimore home!
  7. DIY efforts often backfire: Using the wrong traps, baits, or placement can worsen the problem and create avoidence of control devices
  8. They require a lot of traps: A small home needs at least 6-8 traps, and larger infestations require significantly more.

Interesting Facts and General Information about Mice:

Mice are omnivores, which means they eat both meat and plants. While they primarily eat seeds and insects in the wild, as the weather cools and they go inside, mice will eat almost anything they can find. This includes:

  • Pet food
  • Grains
  • Bird seed
  • Fruits
  • Vegetables
  • Insects
  • Meat
  • Soap
  • Candy
  • Anything you will eat

This varied diet allows them to thrive in many different environments and makes it challenging to control them through food restriction methods alone.

While mice do eat cheese, they tend to prefer carbohydrate-rich foods, such as rice and grains.

House mice do not hibernate, but white-footed mice a.k.a. field mice are known to hibernate.

Mice have relatively short lifespans, averaging 8-12 months. House mice have an average lifespan of 9-12 months, while field mice survivability can be as short as 2 months due to predators.

Mice can be found all year round but Maryland homeowners usually notice them inside from September to January when they seek shelter from dwindling food sources outdoor and cooler temperatures.

Mice stay active through spring and summer as they search for food and nesting materials. Luckily, proper prevention measures keep them at bay no matter the time of year.

How do I keep ants out of the house?

Here’s how to keep ants out of your house and maintain a pest-free environment:

  • Keep your kitchen, dining room, and pantry clean. Regularly sweep the floors, wipe off countertops daily, and ensure all food items are properly sealed.
  • Act quickly to clean up food spills. If you accidentally spill food or drink, make sure to promptly clean it up to avoid attracting ants.
  • Eliminate food crumbs after every meal. Thoroughly wipe down counters and tables with warm soapy water to remove any food residue. Pay attention to crevices and corners where crumbs can hide. This is especially important if you have young children who tend to leave crumbs around the living room or kitchen.
  • Keep surfaces dry. Ensure that counters, sinks, and floors are thoroughly dried after cleaning or any spills. Standing water or moisture can attract ants.
  • Take out the trash promptly and keep garbage cans tightly sealed. Dispose of trash, particularly items with strong odors, immediately after use. Remember, ants are drawn to sugary treats!
  • Store food in sealed baggies or airtight containers. Avoid leaving any food uncovered as it can easily attract ants.
  • Maintain cleanliness around your pet’s food area. Keep your pet’s food bowl clean and tightly seal pet food containers. Pets may leave behind crumbs after eating, so be sure to sweep or vacuum the area regularly. Consider storing pet food in a large, airtight plastic container instead of its original packaging.
  • Monitor indoor humidity levels. Certain ant species, like odorous house ants, acrobat ants, and carpenter ants, are attracted to damp wood for its moisture content. Be mindful of indoor humidity and address any potential moisture issues promptly.

How do I keep ants out of the yard?

Here’s how to keep ants out of your yard and maintain a pest-free outdoor space:

  • Trim outdoor branches and shrubbery. Cutting back all of the branches and shrubbery close to your home can inhibit ants from nesting. Ants use these elements to bypass the treated perimeter of your home.
  • Don’t over-mulch. It’s recommended to keep mulch depth under three inches.
  • Don’t leave tree stumps or rotting wood lying around. Rotting wood attracts ants. Avoid any situations where wood is in direct contact with the ground or right next to your home. Monitor wood decay and replace damaged wood as necessary.
  • Eliminate yard debris, especially close to your home. Remove piles of debris, like leaves, firewood, or bricks, and ensure your gutters aren’t clogged.
  • Notice the plants in your yard. Control aphids, a.k.a. plant lice, on your favorite flowers and shrubs, such as crepe myrtles, rose bushes, American holly, peonies, any type of maple, and English ivy.
  • Be mindful of your neighbors’ yards. Ant colonies like odorous house ants are very large, have multiple queens, and spread across multiple properties. This is especially true if your home is in close proximity to neighbors, such as most single-family and townhome communities. Therefore, while we can exterminate ants from your home and property, there’s a good chance the remaining ants on your neighbor’s property will make their way back to yours at a future point. For these reasons, a regular inspection plan is needed to ensure long-term ant management.
