Bat infestations in attics are a serious problem. Bat droppings, or guano, present health risks and cause significant damage to your home. Cleaning it up requires caution and the right approach. This guide details how to safely and effectively clean up bat poop from your attic. Safety is paramount; always prioritize your health.

Assessing the Situation: Before You Begin

Before you start cleaning, assess the extent of the infestation. This crucial step ensures you have the right equipment and plan.

1. Determine the Severity of the Infestation

Small Infestation: A few droppings scattered in a limited area.
Moderate Infestation: A larger area covered in droppings, potentially some nesting material.
Severe Infestation: Extensive guano buildup, significant nesting materials, and possibly a large colony.

2. Identify Potential Health Hazards

Bat guano can contain histoplasmosis, a fungus that can cause lung infections. Never disturb the droppings without proper protective gear. If you suspect a large infestation or are unsure about your abilities, contact professional wildlife removal and cleanup services.

3. Gather Necessary Supplies

You'll need the following:

N95 respirator mask: Crucial for preventing inhalation of harmful spores.
Protective eyewear: Goggles or safety glasses to shield your eyes.
Gloves: Thick rubber gloves to protect your hands.
Tyvek suit: A full-body protective suit is highly recommended, especially for larger infestations.
Heavy-duty plastic bags: For disposing of contaminated materials.
Shop vacuum with HEPA filter: Essential for safely removing guano. A standard vacuum will spread spores.
Broom and dustpan: For initial cleanup of larger debris.
Bleach solution (10% bleach, 90% water): To disinfect surfaces after cleaning (use with caution and proper ventilation).
Deodorizer: To neutralize unpleasant odors.
Plastic sheeting: To contain the mess and protect your flooring.

Step-by-Step Guide to Cleaning Bat Guano

Follow these steps carefully to minimize health risks and effectively clean your attic:

1. Prepare the Attic

Seal off the area to prevent the spread of dust and spores. Cover floors and any exposed surfaces with plastic sheeting. Turn off any electricity to avoid accidents.

2. Protective Gear is Essential

Put on all your protective gear before entering the attic: respirator, gloves, eyewear, and Tyvek suit.

3. Remove Large Debris

Carefully use a broom and dustpan to remove larger pieces of guano and nesting materials. Place them immediately into heavy-duty plastic bags. Seal the bags tightly.

4. Vacuuming Bat Droppings

Use the shop vacuum with the HEPA filter to thoroughly clean up the remaining guano. Work systematically, overlapping passes to ensure complete removal.

5. Disposing of Waste

Dispose of all contaminated bags and vacuum contents according to local regulations. Often, these require special hazardous waste disposal. Check with your local waste management company.

6. Disinfect the Area

After cleaning, thoroughly disinfect the area with a 10% bleach solution. Allow it to sit for at least 10 minutes before rinsing.

7. Air Out the Attic

Open windows and doors to air out the attic completely before re-entering. Use a deodorizer to eliminate any lingering smells.

8. Bat Exclusion

Once cleaned, it’s critical to prevent future infestations. Contact a wildlife removal professional to seal any entry points and safely relocate the bats.

Preventing Future Bat Infestations

Preventing future bat infestations requires proactive measures:

Seal entry points: Inspect your attic for cracks, gaps, and holes. Seal them with caulk, steel wool, or other appropriate materials.
Regular inspections: Inspect your attic periodically to check for signs of bat activity.
Professional help: Consider hiring a wildlife control specialist for larger infestations or if you're unsure how to handle the situation.

When to Call a Professional

If you're dealing with a large infestation, suspect a health risk, or are uncomfortable performing the cleanup yourself, it's best to contact a professional wildlife removal and cleanup service. They have the expertise, equipment, and safety protocols to handle the job safely and effectively. Remember, your health and safety are paramount.
