Cleaning Up After Bats and Birds in Mill Valley, CA
Pigeon droppings removal is the cleaning of heavy, caked droppings from structures where birds roost. It can involve scraping, washing, disinfecting and sometimes removal of nests and feathers.
When bats or birds leave droppings on your property in Mill Valley, you get a crew that wets down and contains the material before removal. The team bags it, disinfects the area and checks the finished work. For Marin County jobs, call Mill Valley Biohazard Cleanup Help.
About 80% of homes in Mill Valley were built before 1980, and older attics, vents and rooflines often have gaps where bats and birds can enter. Summers in Mill Valley are milder, with July highs around 82 degrees, but guano in closed attics still dries and turns to fine dust over time.
A typical bird & bat guano cleanup job includes:
- Documentation of the work for buyers, inspectors, landlords and insurers
- Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
- Sealing and bagging of contaminated waste for proper disposal
- Removal and disposal of insulation soaked with guano, urine and nesting debris
- Sorting, cleaning and sanitizing of stored items and belongings that can be saved

Common Questions About Guano Removal in Mill Valley, CA
What should I do first if I find guano?
Do not sweep, blow or vacuum it. Keep people and pets away and leave it undisturbed until you know the size of the job. Call Mill Valley Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.
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 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.
What is histoplasmosis?
Histoplasmosis is a lung infection linked to a fungus that can grow in soil and droppings from birds and bats. People are exposed by breathing in spores. Many exposed people have no symptoms, and anyone who feels unwell after being around guano should tell a doctor.
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.
How do you clean pigeon droppings safely?
