Rodent infestations often leave behind hazardous contamination that can affect indoor environments long after the rodents are gone. Our trained remediation specialists provide professional rodent dropping cleanup, rodent feces removal, sanitation, odor abatement, and environmental decontamination services throughout Northern and Central California.
Rodent infestations can create significant contamination issues inside homes, businesses, warehouses, storage facilities, crawlspaces, attics, and abandoned structures.
Rodent droppings, urine, nesting materials, and contaminated debris may contain harmful bacteria, viruses, parasites, and allergens that can affect indoor air quality and create health concerns for occupants.
Many property owners underestimate the extent of contamination caused by rodents. Even after rodents have been removed, waste materials often remain hidden within insulation, wall cavities, attics, crawlspaces, HVAC systems, and storage areas.
Professional cleanup helps address contamination at its source while reducing potential exposure risks and environmental concerns.
Rodent contamination is much more than simply sweeping up visible droppings.
Improper cleanup methods can disturb contaminated materials and potentially release harmful particles into the air. For this reason, professional remediation procedures focus on safe removal, containment, sanitation, and environmental cleaning practices.
Our rodent dropping cleanup services may include:
Every property presents unique contamination challenges, requiring a customized remediation strategy based on the severity and location of affected materials.
Rodent activity frequently affects areas that remain hidden from daily view.
Our team commonly responds to contamination involving:












In many cases, contamination accumulates over months or years before being discovered. By the time rodent activity becomes visible, significant contamination may already be present throughout the structure.
Professional assessment helps determine the extent of contamination and identify affected areas that may otherwise be overlooked.
Rodent contamination can impact indoor air quality through airborne particles, contaminated dust, allergens, nesting materials, and odor-producing organic matter.
When droppings, urine, and nesting debris accumulate within enclosed areas, environmental conditions may worsen over time and affect both occupant comfort and building conditions.
Our environmental risk management approach focuses on identifying contamination pathways, evaluating affected materials, and implementing remediation procedures designed to support healthier indoor environments.
The longer rodent contamination remains in place, the greater the potential for ongoing environmental concerns.
Potential risks may include:
Prompt remediation helps reduce contamination levels while supporting safer occupancy conditions and improved sanitation.

They made a very difficult situation much easier to deal with. Kimberly and her team were very communicative, informative, and flexible with us. Pricing was transparent and fair, much better than other companies who bid the work. Would absolutely call them again.
Amazing, quite thorough in their work. We called them to cleanup rodent droppings. Left the garage very clean and prestige. Very professional. They cleaned the inside of all the garage cabinets. Every step was explained and photographed and shared with us. Look no further.
From the start, 911hazardcleanup was professional and thorough. The clean up team did an amazing job in what was a hoarder house situation. They went above and beyond to insure that the living situation was brought back to safe and sanitary conditions. I cannot recommend them highly enough.
The 911 crew, from Kimberly and Sean to the clean-up crew, led by Alejandro, were professional and thorough. Kimberly kept me up-to-date regarding scheduling and necessary documents. The clean-up crew was very thorough and even had time to add another small section of flooring. I highly recommend 911 Hazmat Clean-up for any task!
Dependable. Professional. And thorough. I know when they’re on the job it’s going to be done right.
Very nice people to work with!
Stop your search right here! You do not need to go any further. 911 Hazmat Cleaners will take care of you for a very reasonable price in a very difficult situation. I had an unattended death and level 4 hoarder clean up. I was overwhelmed! 911 Hazmat Cleaners was $7,000 cheaper than the other bids. They were perfect in everyway. You couldn’t believe the before and after photos. And the smell afterwards was amazing! They also bought lunch for my husband and me everyday we were there with them. Just mention to the other companies that you are going to talk to 911 Hazmat and watch their faces fall because they know. We were so happy we tipped the guys a hundred dollars each. You will be happy too if you have to use them!
Everyone with whom I worked with at 911 Hazmat was above expectations in satisfaction for the client, consideration for the neighbors, efficiency in their work, positive and supportive throughout the 18 days to complete the cleanup, trustworthy, and so thoughtful to me while I was grieving for my sister and dealing with a toxic cleanup. The documentation of work they did every day with pictures and amounts of trash dumped was especially helpful since I could not physically be onsite once worked started on the property. They give an estimate and stick with it. This company is the BEST.
This company was terrific to work with. They got on the job immediately and did an outstanding job and stayed with it until completion.
