It Came from Nextdoor: Can Your Neighbor’s Pests Invade Your Home? 

We’ve all heard stories about pests spreading from one neighbor’s home to another. While some pests are unlikely to move far from their nest, others are highly mobile and can quickly invade nearby spaces. Here’s what you need to know about pest spread and how to protect your home. 

Pests You Can Get from Your Neighbor 

Some pests are more likely to migrate than others, especially in shared or close living spaces. These are the common culprits: 

1. Mice and Rats 

Mice and rats are highly mobile and adept at finding food and shelter. Their foraging range depends on the species: 

  • Mice typically forage within 25 feet of their nest, making them a threat if your neighbor is nearby. 
  • Rats travel even farther, with a range of 50–150 feet, increasing the likelihood of spread in urban and suburban areas. 

They can easily enter homes through cracks, vents, and gaps in foundations. 

2. Cockroaches 

Cockroaches are notorious for spreading between neighboring properties, especially in shared spaces like apartments. They are highly mobile and can travel: 

  • Through walls, pipes, and ventilation systems. 
  • Across lawns, though this is less common. 

Even small gaps in floorboards, baseboards, and doorways can provide access for roaches. 

3. Bedbugs 

Bedbugs are generally sedentary, but they can spread during severe infestations. They move by: 

  • Traveling through wall voids, electrical wiring, and plumbing. 
  • Hitching a ride on clothing, furniture, or personal belongings. 

Shared hallways or close contact with infested belongings can also facilitate their spread. 

4. Ants 

As ant colonies grow, they require more food and space. Ants are excellent at bridging gaps, whether over lawns or through tiny cracks in walls or windows. If a neighboring colony grows large enough, they may start foraging in your home. 

5. Termites 

Termite colonies spread when winged termites, known as “swarmers,” fly short distances in search of new locations to establish a nest. If your neighbor has termites, your home might offer similarly favorable conditions. 

6. Wildlife 

Wild animals such as raccoons, squirrels, or skunks are drawn to areas where food is readily available. Garbage, pet food, or deliberate feeding by neighbors can attract wildlife to the neighborhood. Once established in the area, they may venture into your yard or even your home. 

How to Protect Your Home 

Effective pest control takes a holistic approach, addressing all aspects of an infestation. Here’s how to safeguard your home from pests potentially coming from a neighbor’s property: 

1. Regular Inspections 

Inspect your property—inside and out—for signs of pest activity. Early detection is crucial for preventing infestations. Look for: 

  • Droppings 
  • Chew marks 
  • Burrows or nests 
  • Signs of structural damage 

Act quickly at the first signs of a problem. 

2. Remove Attractants on Your Property 

Sometimes the source of the pest issue may not be entirely your neighbor’s fault. Inspect your own space for potential attractants like: 

  • Unsecured garbage cans. 
  • Food waste or spilled birdseed. 
  • Outdoor pet food or water dishes. 

Eliminating these attractants will reduce the chances of pests entering your home. Ensure your home is not contributing to the problem before discussing it with your neighbor. 

3. Seal Potential Entry Points 

Prevent pests from entering your home by sealing cracks, gaps, and holes in your walls, foundation, and around doors and windows. Use materials like: 

  • Steel wool or caulking for small gaps. 
  • Weather stripping to seal around doors and windows. 

If you rent, report these issues to your landlord and request repairs. 

4. Inspect Your Belongings 

Pests like bedbugs and cockroaches can hitchhike on personal items. Be mindful of: 

  • Clothing, bags, and backpacks: Check them before bringing them indoors. 
  • Furniture or secondhand items: Carefully inspect them for signs of pests before introducing them to your home. 

Avoid placing belongings on the ground in hallways or other shared spaces. 

5. Communicate with Your Neighbor 

Pest control often requires cooperation. If your neighbor’s pest problem is affecting your home, approach them carefully: 

  • Avoid accusations. People are more likely to respond positively if you express concern rather than blame. 
  • Suggest collaboration. If possible, work together to resolve the issue. For instance, coordinating pest control treatments on the same day can significantly improve effectiveness. 

6. Contact the Property Owner or Landlord 

If you’re a renter, report pest issues to your landlord in writing. Document: 

  • What steps you’ve taken to address the issue. 
  • Conversations you’ve had with your neighbor. 
  • Specific problem areas requiring attention. 

Homeowners facing persistent issues may benefit from consulting a professional pest control service to assess and resolve the problem. 

Final Thoughts 

Pests often spread in neighborhoods where humans and homes are close together. Understanding how pests move and taking proactive measures to secure your home can minimize your risk. By maintaining open communication and addressing potential attractants, you can protect your space and live pest-free—even next to a neighbor with a problem.
