Histoplasmosis-Aware Guano Removal in Martinez and Contra Costa County
Bat guano removal is the careful collection of bat droppings, usually from attics and wall voids, using wet methods and containment. It protects people from dust that can carry fungal spores.
Guano is a respiratory risk, so your Martinez property gets containment, wet methods and protective gear, then disinfecting and inspection before the space is handed back to you. For Contra Costa County owners, call Martinez Biohazard Cleanup Help.
Most housing in Contra Costa County is occupied, with a vacancy rate of about 4%, but attics, chimneys and outbuildings can still go unchecked for years. Martinez is on the drier side, with about 19 inches of rain a year, so old guano dries out fast and turns to fine dust that must be wetted before removal.
What bird & bat guano cleanup covers:
- Containment and wet removal of bat guano from attics, wall voids and rafters

- Documentation of the work for buyers, inspectors, landlords and insurers

Common Questions About Guano Removal in Martinez, 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.
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.
Can guano get into ductwork or vents?
Yes, if birds or bats roost near vents or intakes, droppings and dust can enter air paths. Cleanup may include treating vent openings and nearby surfaces.
Do I need to replace attic insulation after guano?
Usually, if droppings or urine have soaked into it. Soiled insulation holds contamination and odor and cannot be reliably cleaned. After removal, new insulation is installed as a separate job.
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 Martinez Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.
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.
