Bio-One of Madison decontamination and biohazard cleaning services


MadisonRodent Droppings

Rodents are more than bothersome creatures. They often carry bacteria and parasites in their waste. It may seem like a simple pickup job. But if not sanitized and removed professionally, much of the bacteria and parasites remain. It’s as if it was never cleaned in the first place.

You called the right 
team for the job.

Rodent droppings may seem minor, but they often carry viral diseases:

  • Leptospirosis
  • Arenavirus
  • Hantavirus Pulmonary Syndrome

Rats, mice, pigeons, and cockroaches are all examples that fall under this category. Regardless of how long it’s been, bacteria will remain until properly sanitized.

Oftentimes, the bacteria within rodent droppings, saliva, or urine are airborne as well. This alone causes serious problems with food and water sources. It can be very difficult to thoroughly disinfect. 

We specialize in the removal, decontamination, and disinfection of this animal waste. Any impacted areas will be thoroughly sanitized and all waste removed. Regardless of what’s happened, we will take care of you. 

We’ve been a part of the Madison, WI community for many years now and are proud to help keep it clean. We strive to make a difference in your lives. We truly care. As the owner of this business, I, Angela Welbes and David Levin, can promise that you’ll receive the best help available from the professionals at Bio-One of Madison.

I cannot begin to put into words the satisfaction we have with the services provided by David, Angela, and their entire Bio-One team. From the moment we called them to discuss our needs in helping to clean out a home due to a death of a loved one, to the day the final steps were completed to put the property back in order, they were so easy to work with. Not only are Bio-One's service impressively comprehensive, but they do their work in such a compassionate way. Their communication is among the best we have ever experienced from any service provider. We cannot recommend them highly enough. Rob & Dawn Lefeber

I just want to give a HUGE recommendation for Bio-One. I know most of us have worked with them on cases in the past, but this particular case I am working on right now with them, they are going above and beyond and deserve an extra shout out. My client's home was one of the worst I've ever seen. They got out there within a day to get thins cleaned up. They changed his lightbulbs, replaced the corroded toilet, got him set up with some bedsheets, towels, kitchen equipment, etc. all things they had in their garage so he would be set up for success after the major clean out. They even helped with some pest control to get rid of the rats/mice that have overrun the home. They have been so willing to help my client and work with us and I just feel that we are lucky to have them as a vendor/support in our community :)

I'll add the same review I put on Google: "Angela, David, and their coworker at BioOne did an ABSOLUTELY AMAZING job for us. They were exceptionally sensitive to a rough situation, extremely professional, and gave us a very reasonable quote. Very timely. The work was done beautifully and quickly, and they made it look like a "home" again. Nice extra touches too. I would recommend them without hesitation to anyone (personal or business). It's clear these folks take great pride in their work and their business. I'll be keeping their card around and will call again if needed!!!"

David and Angie were real life savers for my niece who has special needs. They were responsive to our calls and questions. I new I could not do it and when I found them and talked with them, I knew I had found the right team. David and his team arrived on time and worked so hard to restore her apartment to a clean safe environment for her to live in. My niece was treated with kindness and respect and participated in the decisions on what to keep and what to throw away. I highly recommend them.

Angie and David helped us clean up our drop ceiling after we discovered the aftermath of a prior mouse problem in the house we purchased. They were extremely responsive and starting working on the issue immediately. It was a challenging job and they made sure that it was done with a high level of quality and attention to detail!

David and Angie responded immediately and were onsite within 45 minutes in response to a death at home that resulted in serious decomposition. They are professionals who are well-equipped to thoroughly clean, remove waste, sanitize, and eliminate pervasive odor with ozone. They returned each day for 4 days until they and we were confident that their job was complete. They are a great team who does everything well to assure excellence. We highly recommend them.

This company was absolutely amazing, from the quick response time to my inquiry to a remarkable clean-up completed the next day. Everyone I dealt with on the team was professional, compassionate, kind and discreet. The cost was completely reasonable. I unconditionally recommend Bio-One Madison to anyone needing clean-up services due to hoarding, extreme filth or other difficult cleaning situations.

We have recently started working with Bio-One on a bunch of our apartments. They do an amazing job. Professionalism is just one of their great qualities. When we request service, they are very quick to fit us in their schedule. Time sensitivity is very important when it comes to some of our bio-hazard units so we appreciate the quick turnaround. We would highly recommend them to anyone!
