Health Risks Associated with Squirrel Infestations: Identifying Diseases and Preventative Measures

Squirrel infestations can pose significant health risks to humans due to the potential transmission of various diseases. While squirrels may appear harmless and cute, their presence in and around homes can lead to serious health concerns. Identifying these risks and implementing preventative measures, including squirrel removal, is crucial for maintaining a safe and healthy environment.

Identifying Health Risks

  • Transmission of Diseases: Squirrels can carry diseases such as leptospirosis, tularemia, and salmonellosis, which can be transmitted to humans through contact with their urine, feces, or saliva. These diseases can cause flu-like symptoms, gastrointestinal issues, and in severe cases, organ failure.
  • Allergies: Squirrel dander and fur can trigger allergic reactions in sensitive individuals, leading to respiratory problems such as asthma or allergic rhinitis.
  • Damage to Property: Squirrels are known to gnaw on wood, insulation, and electrical wiring, which can pose fire hazards and structural damage to homes. Additionally, their nesting materials can block vents and chimneys, leading to ventilation issues and potential carbon monoxide poisoning.

Preventative Measures

  • Sealing Entry Points: Conduct a thorough inspection of your home to identify and seal any potential entry points that squirrels could use to gain access. This includes gaps in the roof, vents, and cracks in the foundation.
  • Proper Food Storage: Keep food stored in airtight containers to prevent attracting squirrels and other rodents into your home. Bird feeders should be placed away from the house and equipped with squirrel-proofing mechanisms.
  • Trimming Trees and Shrubs: Trim tree branches and shrubbery away from your home to prevent squirrels from gaining easy access to your roof and attic spaces.
  • Squirrel Removal: If you suspect a squirrel infestation, contact a professional wildlife removal service to safely and humanely remove the squirrels from your property. Attempting to handle wild animals on your own can be dangerous and ineffective.


Squirrel infestations pose significant health risks to humans, including the transmission of diseases and property damage. Identifying these risks and implementing preventative measures, such as sealing entry points, proper food storage, and squirrel removal, is essential for protecting your home and family. By taking proactive steps to address squirrel infestations, you can maintain a safe and healthy living environment for everyone.
