- Odor removal and deodorizing of ammonia-like smells left by droppings
- Sorting, cleaning and sanitizing of stored items and belongings that can be saved
- HEPA-filtered vacuuming and air cleaning to capture fine dust after removal
- Documentation of the work for buyers, inspectors, landlords and insurers

Guano Cleanup Frequently Asked Questions in Merced Heights, San Francisco, CA
What rules apply to guano cleanup in California?
Worker safety follows OSHA rules for hazardous dust, and waste disposal is handled according to local requirements. Rules about moving or excluding bats and other wildlife can vary by species and season, so check with a wildlife professional first.
Who pays for guano cleanup in a rental?
It depends on the lease and local law. Tenants should tell the landlord or manager right away. A landlord, an attorney or a tenant rights group can say who is responsible.
Can I clean a small amount of guano myself?
Sometimes. For a small spot, wear gloves, eye protection and a mask, wet the droppings lightly and wipe them up. Do not sweep or blow them dry. Thick, old or large deposits and attics are better left to a team.
Is it safe to stay home during guano cleanup?
For work in a sealed attic, many people stay in the home while crews work with containment. For heavy contamination or open spaces, it may be better to stay away. The team will say what is best for your situation.
Can you get sick from bat droppings?
Yes, mainly from breathing in dust from dry droppings. Risk is higher with old, heavy buildup in enclosed spaces. People with asthma, lung conditions or weak immune systems need extra care and should stay out of the area.
Will the smell go away after cleanup?
Often yes, once the guano and soaked materials are removed and the area is treated. Deep stains in wood or drywall may need extra treatment, and the crew can say what to expect.
