Bat Guano Removal

Guano is another term for bat dung or bat feces. Bat guano carries fungal spores that cause Histoplasmosis, which can be fatal to humans. Histoplasmosis is caused by breathing in fecal dust matter. Bat guano must be handled similar to asbestos since the threat of disease is great. Be sure to have employees fully protected by wearing Tyvek suits, boots, full face respirators or partial respirators with goggles, hard hats, and rubber gloves with cloth work gloves over them (this makes it easier to work with tools).

Basic Method

1. Wet down the affected area with Microban X-590 using a Flex-A-Lite ULV (Ultra Low Volume) Fogger starting on the fine mist setting and moving to course fog. This initial fogging will kill anything that may be flying around that could bite technicians.
2. Open a window or vent the attic for negative air pressure. It is important to draw air to the outside and not back inside the structure.
3. Contact spray Microban Germicidal Cleaner Concentrate (lemon fragrance) diluted at 16 oz per gallon of water.
4. To remove guano, have one employee spray the affected area with Microban Germicidal Cleaner while another employee shovels the guano into double plastic bags.
5. Contact your local landfill to make sure they will take the guano.
6. Clean the area with Microban Germicidal Cleaner Concentrate.
7. Apply Unsmoke Unsoot #1 with Micropel. Dilute Unsoot #1 with 4 parts water and spray all surfaces using the Blastmaster fogger.
