How to Get Rid of Rats in Wall?

How to Get Rid of Rats in Wall?

Rats and mice are part of the rodent family, characterized by their sharp front incisors that continuously grow throughout their lives. There are over 60 species of rats worldwide, but the two most common troublemakers in homes are the Norway rat (Rattus norvegicus) and the roof rat (Rattus rattus). These critters have adapted remarkably well to human environments and are known for their rapid reproduction rates.

Today, you will join the rat removal experts in the Dallas-Fort Worth area, Critter Stop, to answer a very important question: how to get rid of rats in the wall? In this article, we will give you some advice about how to handle this problem. 

Rats in Wall
Your walls could become a high-traffic highway for rats inside your house. 

Understanding the Pest Problem

Rat infestations are a persistent issue faced by homeowners around the world. The problem goes beyond the annoyance of hearing scratching sounds in your walls or finding chewed-up wires; rats can pose serious health risks.

They are vectors for various diseases, including hantavirus, leptospirosis, and salmonellosis. Furthermore, they can be destructive to your property, causing damage to insulation, and woodwork, and even posing fire hazards by gnawing on electrical wires.

Also, when we have provided rat removal services, we have found that having rats living in the wall is just one side of the problem, when you start feeling a dead rat smell in walls, is this phase when the situation levels up to a more noisy and risky problem. Let's continue reading some tips to know how to identify and prevent this situation. 

Identifying the Rat Infestation

Rats are nocturnal creatures, making them difficult to spot directly. However, they often leave unmistakable signs of their presence. Look out for rat droppings, which are small, pellet-like, and dark in color. You might also hear scratching or scuttling noises in your walls, especially at night. Another sign of their presence is having rat holes in walls, which is like a small way for them to move inside your walls. An unusual, musty odor is another telltale sign of a rat infestation.

Common Damage Caused by Rats

Understanding the extent of damage rats can cause is essential. Their constant gnawing can weaken the structural integrity of your home. They'll chew through anything, including plastic, wood, and even concrete if it's in their way. Insulation is a favorite nesting material, and they can shred it to pieces, rendering it ineffective. Perhaps most alarmingly, rats are responsible for numerous house fires due to their tendency to gnaw on electrical wires.

Inspecting for Entry Points

Rats are remarkably agile and can squeeze through tiny openings. Inspecting your home for potential entry points is vital to keeping them out. Check for gaps in your walls, foundation, or roof, as well entry holes such as openings around utility pipes and vents. Seal these openings with materials like steel wool, caulk, or wire mesh to prevent rats from entering.

Prevention and Management

Rats are ingenious when it comes to squeezing through tight spaces, making it crucial to fortify your home's defenses against their intrusion. Here's a closer look at sealing access to attic entry points effectively:

  1. Inspect and Identify Entry Points: Begin by conducting a thorough inspection of your home's exterior and interior. Look for gaps, cracks, and holes that rats could exploit. Pay particular attention to areas around pipes, vents, and utility lines as these are common entry points.
  2. Choose Robust Materials: Rats are relentless chewers, capable of gnawing through wood, plastic, and even soft metals. Opt for materials that are rat-proof, such as metal mesh, steel wool, or cement. These materials can be extremely effective at blocking rat access.
  3. Seal Gaps Tightly: When sealing entry points, ensure a snug fit. Rats are persistent, and even a small gap can provide them with an entryway. Use appropriate adhesives or fasteners to secure your chosen material in place.
  4. Regular Maintenance: Rats may attempt to chew or claw their way back in if they sense any weakness in your barriers. Regularly inspect and maintain these seals to ensure they remain intact and rat-proof.

Eliminating Food Sources

Rats are drawn to homes with accessible food sources. To deter them effectively, follow these steps to further eliminate rats from potential food temptations:

  1. Secure Food Storage: Store all food items in airtight containers, including grains, cereals, and pet food. Rats have an acute sense of smell and can detect food from a considerable distance. Airtight containers help keep odors contained.
  2. Clean Up Thoroughly: Promptly clean up any food crumbs, spills, or scraps. Rats are scavengers and will gladly feast on even the tiniest remnants of food. Regularly sweep and mop kitchen floors and countertops.
  3. Garbage Control: Ensure your garbage cans have tightly fitting lids. Rats are opportunistic feeders and won't hesitate to rummage through your trash for a meal. Empty your trash regularly, especially if it contains food waste.
  4. Pet Food Management: If you have pets, don't leave their food out overnight. Rats are notorious for helping themselves to pet food, and this can inadvertently attract them to your home. Feed your pets during designated times and store their food securely.

Water Management

Rats need water just as much as they need food. Proper water management can help deter rats climb using them effectively:

  1. Fix Leaks: Rats can detect and follow water sources to your home. Inspect your plumbing for any leaks and repair them promptly. This will remove a potential water supply for rats.
  2. Rain Gutters and Downspouts: Ensure that rain gutters and downspouts are correctly maintained and directing water away from your home's foundation. Accumulated water near your property can attract rats seeking hydration.
  3. Outdoor Water Sources: Pay attention to outdoor water features like birdbaths and ponds. Rats may use these as water sources. Consider installing netting or barriers to deter them from accessing these areas.

Traps and Bait Station

When it comes to rat traps, selecting the right type can significantly impact your success in dealing with a rat infestation. Here, we explore various types of rat traps along with their advantages and disadvantages:

  1. Snap Traps:
    • Advantages: Snap traps are classic, efficient, and economical. They are quick and effective at killing rats.
    • Disadvantages: They can be a bit gruesome to use, and disposing of deceased rats can be unpleasant.
  2. Electronic Traps:
    • Advantages: Electronic traps offer a humane way to deal with rat infestations. They deliver an electric shock that quickly kills the rat, ensuring a swift and humane death.
    • Disadvantages: They are more expensive than snap traps and require a power source or batteries.
  3. Live Traps:
    • Advantages: Live traps capture rats alive, allowing for a catch-and-release approach. They are a humane option for those who prefer not to harm the rats.
    • Disadvantages: It may be challenging to release rats far enough from your home to prevent their return, and rats can become stressed in captivity.
  4. Glue Traps:
    • Advantages: Glue traps are effective at capturing rats without harming them. They are easy to set up and relatively inexpensive.
    • Disadvantages: They are considered less humane as rats can suffer before succumbing. It can also be challenging to remove live rats from glue traps.

Placing Traps Strategically

Strategic trap placement is essential for success in rat control. Here are some key considerations for placing traps effectively:

  1. Identify Rat Runways: Rats tend to follow specific pathways or runways, typically along walls and in corners. These are ideal locations to set traps.
  2. Spacing: Use an adequate number of traps. In cases of severe infestations, it may be necessary to set multiple traps. For best results, place them at intervals of 5 to 10 feet along runways.
  3. Safety First: Keep traps out of reach of children and pets. Consider using bait stations or placing traps in areas inaccessible to them. Always follow safety guidelines provided with the traps.
  4. Camouflage Traps: Rats are wary creatures. Conceal traps with cardboard boxes or other materials to make them seem less threatening. Rats are more likely to investigate and trigger a baited trap that doesn't look out of place.

Choosing Effective Bait

Selecting the right bait is a critical aspect of successful rat trapping. Rats can be cautious, so offering an enticing bait can make all the difference:

  1. Peanut Butter: Peanut butter is a proven rat magnet. Its strong scent and sticky texture make it hard for rats to resist. Spread a small amount on the trap's trigger.
  2. Dried Fruits: Rats have a sweet tooth. Dried fruits like raisins, dates, or prunes can be effective bait options. Secure a piece to the trap trigger with thread or dental floss.
  3. Bacon: The strong odor of bacon can lure rats to the trap. Secure a small strip of bacon to the trigger using wire or string.
  4. Experiment: Rats can be selective, so don't be discouraged if one bait doesn't work. Experiment with different baits to see what attracts the rats in your specific situation. Remember to refresh or replace bait regularly to keep it enticing.

By understanding the various trap options, placing them strategically, and selecting effective bait, you can increase your chances of successfully dealing with a rat infestation. Be patient and persistent, as it may take some time to eradicate the problem completely.

As a humane removal company, we encourage all homeowners to use methods that don't put rats at risk. If you are looking for an answer to “How to kill a rat in the wall?”, you could look at that information reading on another site. 

Repellents and Natural Solutions

Rat repellents and natural solutions offer a diverse array of options to deter these unwanted rodents from invading your space. Here's a closer look at these methods:

Using Repellents and Deterrents

Commercial repellents and deterrents are designed to make your home less inviting to rats in walls. Here are some common options:

  1. Ultrasonic Devices: Ultrasonic rat repellent devices emit high-frequency sounds that are unpleasant for rats but generally inaudible to humans. These devices create a sonic barrier that rats find disorienting and uncomfortable, discouraging them from entering your home.
  2. Sprays and Granules: There are rat repellent sprays and granules available that can be applied to specific areas or entry points. These products often contain natural or chemical ingredients that rats find aversive, deterring them from those areas.
  3. Physical Barriers: Installing physical barriers like rat spikes or wire mesh can prevent rats from accessing specific areas of your property. These barriers can be particularly effective when placed around entry points or favored rat pathways.

Using these tools could help you avoid not only their presence in your house also, but also, these repellents can prevent you from finding a rat nest in wall,  a very big complication in the rat problem because you will be dealing with a whole family of rodents. 

Natural Alternatives for Rat Control

For those who prefer eco-friendly and natural solutions, there are several options that can be both effective and safe:

  1. Essential Oils: Rats have a strong sense of smell, and certain scents can repel them. Essential oils like peppermint, eucalyptus, and citronella are known to be effective rat deterrents. Soak cotton balls in these oils and place them in rat-prone areas or entry points.
  2. Mothballs: Mothballs emit a strong odor that rats find unpleasant. Place mothballs strategically in areas where rats are likely to enter or nest. However, be cautious with mothballs, as they contain toxic chemicals that can be harmful to pets and children.
  3. Ammonia-Soaked Rags: Rats dislike the strong smell of ammonia. Soak rags or cloths in ammonia and place them in areas where rats are active or entering your home. Replace the rags regularly to maintain their effectiveness.

Pet-Friendly Approaches

If you have pets in your home, it's crucial to prioritize their safety while addressing a rat problem. Here are some pet-friendly approaches:

  1. Pet-Safe Traps: Use traps that are specifically designed to be safe for pets. These traps are typically enclosed, preventing your pets from accessing the bait or the trapped rat.
  2. Natural Deterrents: Choose natural deterrents like essential oils or ammonia- soaked rags that are safe for pets. Keep them out of reach to prevent your pets from coming into contact with them.
  3. Supervision: While using any rat control method, supervise your pets closely, especially if they are curious or prone to exploring new objects. Ensure they cannot access traps or repellents.

By considering the safety of your pets and using natural alternatives or pet-safe methods to kill rats, you can effectively deter rats while maintaining a secure environment for your furry companions.

Health and Safety Concerns

The health and safety risks associated with rats are a significant concern when dealing with a rat infestation. Understanding these risks and adopting safe cleanup and disposal methods for rat bodies is crucial for protecting your health and well-being.

Disease Risks Associated with Rats

Rats are notorious vectors for several diseases that can be transmitted to humans. Here's a closer look at some of the diseases associated with rats:

  1. Leptospirosis: This bacterial infection is transmitted through contact with rat urine or contaminated water. Symptoms can range from mild to severe and include fever, muscle pain, and potentially kidney or liver damage.
  2. Hantavirus: Hantavirus is primarily transmitted through inhalation of airborne particles from rat droppings, urine, or saliva. Initial symptoms may resemble the flu but can progress to severe respiratory distress, and in some cases, it can be fatal.
  3. Salmonellosis: Rats can carry Salmonella bacteria, which can contaminate food and water sources. In humans, this can lead to gastrointestinal symptoms, including diarrhea, vomiting, and fever.


To protect your health from these diseases, consider the following preventive measures:

  • Avoid direct contact with rats, their droppings, urine, and nesting materials.
  • Wear protective gear such as gloves and a mask when cleaning up rat-infested areas.
  • Ensure proper ventilation when cleaning to reduce the risk of inhaling airborne particles.
  • Wash your hands thoroughly with soap and warm water after handling anything potentially contaminated by rats.

Safe Cleanup and Disposal Methods

Once you've successfully eliminated the dead rats, it's essential to follow safe cleanup and disposal procedures:

  1. Rat Droppings and Urine:
    • Wear disposable gloves and a mask when handling rat droppings, urine, or contaminated materials.
    • Use paper towels or disposable cloths to carefully pick up droppings and urine. Avoid sweeping or vacuuming, as this can release airborne particles.
    • Double-bag the collected materials in sealed plastic bags before disposing of them in an outdoor trash container.
    • Thoroughly clean and disinfect the affected area using a bleach solution (1 part bleach to 10 parts water) or a commercial disinfectant.
  2. Nesting Materials:
    • Remove nesting materials such as shredded paper, insulation, or fabric using gloves and a mask.
    • Double-bag the materials and dispose of them in an outdoor trash container.
    • Clean and disinfect the nesting area as you would with droppings and urine.
  3. Carcass Disposal:
    • If you've used traps to capture rats, wear gloves when handling the traps with deceased rats inside.
    • Place the entire trap with the rat inside into a plastic bag, seal it, and dispose of it in an outdoor trash container.
    • Clean and disinfect the area where the rat was trapped.

By following these safe cleanup and disposal methods, you can minimize the risk of disease transmission and ensure a clean and hygienic living environment once the rat infestation is under control.

I’d give a 10 star review if I could! We had a great experience with Critter Stop. Everyone I dealt was friendly, professional, and reassuring. Phillip was very helpful and knowledgeable about the work he was doing. He walked me around the entire house to make sure I saw and understood the services he provided. He was also really nice and answered all my questions — he is exactly the type of person that should be interacting with customers.I love the fact that they will come back for up to 1 year after installation if any problems occur — this shows me they stand behind their work.The owner was great too, he personally came to my house and walked me through their offering. I recommend critter stop to anyone and everyone!

Critter Stop is a fantastic business! Everyone involved is extremely professional and very easy to communicate with. Chisam, the owner, did a great job of explaining the process to get the squirrels out of my attic during the initial free estimate. The exclusion crew who did all of the initial work was fabulous. The crew consisted of Phillip, Nick and Corey who arrived promptly when they said they would. They are happy, positive employees. Everyone is very polite and patient in explaining their work and answering questions. They came back several times to check the traps and finish it off with the fogging. Lester was very good about following up to schedule each trap check with me, and the office staff who took care of the billing was very efficient. Critter Stop is a well run company with honest, trustworthy employees! Thank you to all of you who worked hard to make my attic critter free and for the peace of mind that you guarantee your work. Great to know I can call them if for some reason a squirrel figures out a way to get back in!
