Histoplasmosis-Aware Guano Removal in Boulder and Boulder County

Bird droppings cleanup covers pigeon, starling and sparrow droppings on roofs, ledges, balconies, rafters and rooftops. Dry droppings can turn to fine dust, so they are wetted before they are scraped and bagged.

If you are a homeowner, landlord or property manager in Boulder, CO, you can get bat and bird guano removal. Crews work at any hour in attics, lofts, rooftops, chimneys, balconies and warehouses across Boulder County. To start, call Boulder Biohazard Cleanup Help.

Boulder is on the drier side, with about 21 inches of rain a year, so old guano dries out fast and turns to fine dust that must be wetted before removal. About 55% of homes in Boulder were built before 1980, and older attics, vents and rooflines often have gaps where bats and birds can enter.

The work often covers:

Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
Removal of nests, feathers and carcasses left by birds or bats
Sealing and bagging of contaminated waste for proper disposal
Cleanup after wildlife exclusion, once bats or birds have been removed by a professional
Odor removal and deodorizing of ammonia-like smells left by droppings

How Guano Cleanup Works in Boulder, CO

1. Safety first

The crew checks for weak flooring, tight access and other hazards, then sets up lighting, protective gear and containment.

2. Suppress the dust

Technicians put on respirators and suits, then lightly wet the guano to keep fine particles from rising.

3. Remove what cannot be cleaned

Soiled insulation, stained cardboard and nesting debris go into sealed bags, and hard surfaces are scrubbed.

4. Clean the air and surfaces

HEPA filtration clears the air, surfaces are disinfected, and the owner is walked through the result.

Guano Cleanup Frequently Asked Questions in Boulder, CO

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.

Can pigeon droppings damage a roof or building?

Yes. Droppings are acidic and can stain and wear down paint, metal and roofing over time. They also clog gutters and drains and create slip hazards on walkways. Cleanup and deterrents work best together.

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.

How do you clean pigeon droppings safely?

Wet the droppings lightly, scrape them into a bag, then wash and disinfect the surface. Wear gloves, eye protection and a mask. Large roost areas, rooftops and enclosed spaces are best left to a team.

Is bird poop a biohazard?

Large amounts of bird droppings are treated as a contamination hazard because they can hold germs and fungal spores. A small spot outdoors is a simple wash. Thick buildup in a closed space needs protective gear and wet methods.
