Why Clean Up Bat Guano in Attics?

If you find yourself in a situation where bats have chosen your property as a residence, acting quickly to remove the bats is essential. However, after the bats have been excluded from your building, you may wonder how best to remove the guano (bat droppings) left behind. You may even ask, “Why clean up bat guano in attics?” This article will detail the importance of cleaning up the bat guano and what precautions must be taken when removing it.

Cleaning up bat guano in attics is important for several reasons:

  1. Health Risks: Bat guano can carry various diseases and parasites, including Histoplasmosis, a fungal infection that affects the respiratory system. Breathing in airborne spores from dried bat guano can lead to serious health issues
  2. Odor and Stain: Bat guano can emit a strong, unpleasant odor as it decomposes. Over time, this odor can permeate your home or business and become difficult to eliminate. It can also stain ceilings, walls, and insulation.
  3. Structural Damage: Accumulated bat guano can be heavy and cause damage to attic structures. In severe cases, it can weaken the ceiling and compromise the structural integrity of your home. 
  4. Fire Hazard: Bat guano is highly flammable. It can pose a fire hazard if it accumulates near electrical wiring or heating equipment. 
  5. Pest Attraction: Bat guano can attract other pests, such as insects and rodents, exacerbating the problem and creating additional issues in your attic.

When cleaning up bat guano, it’s important to take precautions:

  1. Safety Gear: Wear appropriate safety gear, including gloves, a respirator with air filters that are graded for fungal spores, and protective clothing to minimize the risk of contaminant exposure. 
  2. Ventilation: Ensure proper ventilation in the attic to reduce the concentration of airborne particles. Use fans or open windows and doors, if possible. 
  3. Moistening: Lightly mist the guano with water before cleaning to minimize dust and prevent the release of spores into the air. 
  4. Removal: Scoop up the guano using a dustpan or shovel and place it in a sealed plastic bag for disposal. Be careful not to stir up dust or particles.
  5. Disinfection: Clean and disinfect the affected area thoroughly with a suitable cleaning solution to kill any remaining pathogens.
  6. Insulation Replacement: In cases of severe contamination, removing and replacing insulation may be necessary to ensure the attic is completely clean and safe. 
  7. Future Prevention: Before cleaning, prevent bats from re-entering your attic. Seal any gaps in the exterior of your property to ensure bats cannot enter your home again.

It’s important to note that dealing with bat guano can be hazardous, and it’s often best to hire a professional pest control company with experience in bat removal and cleanup to ensure the job is done safely and effectively. A professional attic clean-up company, such as Attic Cleanup, will use air scrubbers during and after clean-up to remove any spores released into the air that may contain Histoplasma Capsulatum. These fungal spores can cause histoplasmosis in humans, dogs, and cats, so minimizing their spread is vital. Remember that some regions have regulations governing bat removal and may require special permits before proceeding with bat removal, so be sure to check your local laws before removing bats from your property. Contact your local attic clean-up company, Attic Cleanup, if you have any questions or need help with guano cleanup.
