Key Takeaways

  • Rats are attracted to the walls of Louisiana homes due to the warmth, shelter, and food sources these spaces provide.
  • Homeowners can identify rat infestations by looking for signs such as scratching sounds, droppings, gnaw marks, and a distinct ammonia smell.
  • Eliminating rats involves creating DIY bait stations, sealing up entry points, setting traps, and using ultrasonic repellers and natural deterrents like peppermint oil.

  • Walls have easy access to areas within your home.
  • Walls provide quiet, undisturbed areas for nesting and raising young.

Signs of Rats in Your Walls

As stealthy mammals, rats spread diseases. However, they leave traces of their presence, which you can take advantage of as homeowners.

Here’s a closer look at crucial indicators of rat activity:

Signs of Rat ActivityDescription
Scratching SoundsOften heard at night when rats are most active.
Mouse DroppingsSmall, dark pellets, typically found near food sources or along walls.
Gnawing MarksDamage to food packaging, furniture, or electrical wires.

Getting rid of rats requires a combination of tactics, from homemade bait stations to natural repellents.

Here are ways to eliminate and kill rats before calling the pest control company.

Create a DIY Bait Station

A DIY bait station can be a cost-effective and efficient way to manage rodent issues. Here’s how you can assemble one with the following materials:

  • A sturdy plastic container
  • Drill or sharp object
  • Protective gloves
  • Bait (e.g., peanut butter, bacon)
StepsAction To Take
Prepare the ContainerUse a drill or a sharp object to make holes in the sides of the plastic container. These holes should be large enough for rats to enter but not so large that non-target animals can access the bait.
Add the BaitWear protective gloves and place your chosen bait inside the container. Popular choices like peanut butter or bacon are highly attractive to rats.
Secure the StationSeal the top of the container with a lid. This precaution helps protect non-target animals and children from accessing the bait.
PlacementPosition the bait station along the walls where rat droppings have been noticed. This will increase the chances of rats entering the station.

Tips for Bait: Baits such as peanut butter are often irresistible to rats, making them excellent choices for your bait station.

Seal Up Entry Points

Preventing rats from entering your home in the first place is crucial. Here’s a checklist and guide for sealing up potential entry points.

  • Gaps around pipes and vents
  • Foundation cracks
  • Small holes in baseboards
  • Openings near roofing

After conducting a thorough visual inspection, use the following materials to seal identified entry points:

  • Steel Wool or Copper Mesh: For stuffing into gaps before sealing.
  • Caulk: For minor cracks and crevices, especially around doors and windows.
  • Metal Sheets: For larger openings, especially in the foundation or roofing, metal sheets can provide a durable barrier against rodents.

Set Rat Traps Inside and Outside

Strategically placing mouse traps inside and outside your home is crucial to managing rat infestations.

When you place traps in secluded areas with high rat activity, always consider the safety of other household inhabitants, including pets and children.

Adopt a Cat

Cats are not only pets but also natural rat deterrents due to their hunting instincts:

  • Natural Deterrence: The presence of a cat can significantly reduce the likelihood of rats settling in an area.
  • Alternatives: For those with allergies, consider using simulated predator scents or periodically borrowing a neighbor’s cat as temporary solutions.

Use Natural Repellents

Natural repellents can deter rats without the need for chemicals. Effective options include:

Natural Repellent OptionsDescription
Peppermint OilSoak cotton balls in peppermint oil and place them near suspected entry points.
Eucalyptus LeavesScatter leaves in areas like the attic or basement to repel rats.
AmmoniaSoaked ammonia rags can be placed strategically, such as in the garage.

Eliminate Water  Sources

Rats constantly search for water, and eliminating access to it can significantly reduce their chances of infestation in your area. 

To ensure you’ve covered all bases in eliminating water sources for rats, use the following checklist:

  • Inspect and repair all indoor and outdoor leaks.
  • Clean gutters and outdoor drains to prevent water buildup.
  • Cover pools and maintain water features to discourage rat access.
  • Remove or secure outdoor pet water bowls at night.
  • Regularly change the water in bird baths and use deterrents like motion-activated sprinklers.
  • Use dehumidifiers in damp areas like basements and crawl spaces.
  • Improve ventilation in areas prone to moisture buildup.
