How Do Rats Get Into Your House?

Rats – the very mention of the word can send chills down your spine. These creatures are surprisingly adept infiltrators, often associated with filth and disease. Despite our best efforts to maintain cleanliness and secure our homes, rats often find a way in, leaving us scratching our heads in confusion and distress.

So, how do these rodents invade our private dwellings so effortlessly? While you might be tempted to jump directly to the solutions, a more practical approach starts by understanding the problem at its root.

Often, there are surprising and ingenious ways rats can worm their way into a ‘rat-proof’ home. The insights we uncover may be the key to winning this battle against these rodents.

Primary Ways Rats Get Into Houses

Cracks and Holes in Walls or Floors

Rats, being remarkably flexible creatures, can squeeze through openings as small as a 20p piece. These could be unsealed gaps around pipes and wires entering your house, cracks in your foundation, or even holes in your walls that you may have overlooked. They use their sharp teeth and strong jaws to enlarge these openings, making way for other rats. Regularly inspecting your property for such vulnerabilities and promptly sealing it with appropriate materials like rodent-proof sealant, steel wool, or hardware cloth can be effective preventative measures.

Climbing Trees and Jumping onto Roofs

Rats are adept climbers; they can quickly scale trees, walls, and cables. If a tree or a tall shrub is too close to your house, rats can use it as a ladder to reach your roof, especially if branches are overhanging. Once on the roof, they can find numerous ways to get inside, like through vents, chimneys, or loose shingles. Keeping trees and shrubs trimmed and away from your walls and roof can help prevent these aerial invasions. Installing guards or caps can prevent entry through vents and chimneys, and regular roof inspections can identify and fix any weak spots in your roofing.

Through Drainage Systems

Drainage systems are another common entry point for rats into your home. Rats are excellent swimmers who can travel through sewer pipes and climb through toilet bowls or into basements and crawl spaces. They can also enter through uncapped or damaged cleanout pipes in your yard. One way to prevent this is to install rat guards or valves in your toilet pipes and ensure all external pipes are in good condition and properly capped. Regular checks and maintenance of your drainage system can go a long way towards keeping these rodents at bay.

Gaps in Doors and Windows

Even the most minor gaps in doors and windows can serve as an entry point for rats. Rodents can take advantage of unattended doors or windows, poorly fitted frames, or damage to door and window seals, sneaking into your home undetected. Gaps under doors are particularly inviting for rats; a rat can squeeze through an opening that you could slide a pencil under. To mitigate this risk, ensure all doors and windows are adequately sealed and consider installing door sweeps or thresholds. Regularly inspect and replace worn-out seals and consider keeping doors and windows closed when not in use, particularly in the evening hours when rats are most active.

Via the Garage

Garages often serve as an unintended invitation for rats. These spaces, generally cluttered and less frequently disturbed, provide perfect hiding spots for rats. They can sneak in through gaps around garage doors or vents or through holes and cracks in the walls. Once inside, they can easily access the rest of your home through the internal door leading to the garage. Keep your garage tidy and regularly check for possible entry points to avoid this. Consider installing a tight-fitting weather seal on the garage door and ensure any vents are covered with a mesh screen to prevent rat incursions.

Through Air Vents

Air vents provide another sneaky entryway for rats. The ducts that lead to these vents often run throughout the house, connecting various rooms and allowing rats to travel freely and undetected. Rats can chew through the vent covers or exploit any existing gaps to gain access. To guard against this, homeowners can install vent covers made of sturdy materials like galvanized steel or stainless steel mesh that rats cannot chew through.

Why Do Rats Come Into Homes?

Rats primarily invade homes for food, water, and shelter. Your home inadvertently offers all three, making it an attractive destination for these clever rodents.

Food left open, unsealed containers, pet food, and even fallen fruit and vegetable scraps in your garden can lure rats into your premises. Similarly, easily accessible water sources, like dripping faucets, pet water bowls, or birdbaths, can attract these creatures. As for shelter, rats are drawn to safe, quiet spaces where they can nest and reproduce. Cluttered attics, basements, wall cavities, and undisturbed storage boxes provide the perfect refuge for these rodents.

By understanding these essential attractions, homeowners can take proactive measures to make their homes less inviting to rats. Reducing food and water accessibility, sealing potential entry points, and eliminating safe nesting spaces can significantly deter rats from infiltrating your home and assist in removing them.

Ways To Prevent Rats Entering Your Home

Seal All Potential Entry Points: Regularly inspect your home for cracks, holes, or gaps through which rats can enter. Seal these openings immediately with rat-proof materials such as steel wool or hardware cloth, which rats cannot chew through. Pay special attention to areas where utilities and pipes enter the home.
Properly Store Food and Waste: Keep food in sealed containers and ensure rubbish bins have tight-fitting lids. Clean up any food scraps or spills immediately. Eliminating accessible food sources makes your home less attractive to rats.
Trim Overhanging Branches: Trim tree branches and shrubs close to your home. Rats can climb trees and jump onto roofs, so trimming them can prevent them from gaining access to your home from above.
Maintain Cleanliness: A clean house is less inviting to rats. Regularly clean and declutter areas like attics, basements, and garages that could provide shelter for rats.
Use Rat Repellents: Natural and commercial rat repellents are available to help keep rats away. Peppermint oil, for instance, is a natural rat deterrent. Spraying it around potential entry points can help keep rats at bay. For more commercial methods, speaking with a rat control professional is recommended.

Wrapping Up: Keeping Your Home Rat-Free

Maintaining a rat-free home requires understanding what attracts these creatures and the proactive management of these factors. Homeowners can significantly reduce the likelihood of a rat infestation by diligently sealing potential entry points, properly managing food and waste, maintaining a clean and clutter-free environment, and using effective rat deterrents. Be sure to also keep an eye on any potential signs rats may be present. Remember, prevention is always better than cure – a little effort in maintaining your home can save you from the potential stress and cost of dealing with a rat problem later on.
