Mike was beyond wonderful in getting the job done. Kind, helpful and knowledgeable, his expertise in his field made my garage look clean and usable again. His quick response to my request and offer for additional help if needed indicated his commitment to his profession and his customers. Absolutely the best!

In May of 2024, I called Mike at Bio-One and he quickly set up an appointment to visit my home in Worcester, MA. A shed attached to my house, the crawl space above it and a finished room in my basement had an infestation of mice and squirrels and their urine and feces were causing dangerous odors and more. Mike is a smart, experienced and trained investigator so he was able to find the source of my problems and to provide a well-planned out solution to my critter problems. I highly recommend Mike and Bio-One to anyone who needs the right and affordable guy and business to provide advice and actions to resolve a wide variety of hazardous conditions. Gary R

The BioOne team expertly and quickly provided their services. They help make a difficult circumstance, straightforward, simple and easier to get through.

This company was very professional and got the quote back to me quickly and got the proposed job done efficiently. Tim was super easy to work with and very accommodating. Great job, guys.

My dog was injured, I had to rush him to the vet, the dog is doing well. My car was covered in blood. They did such an excellent job. My car looks brand new. Very pleased with the results. They were fast with their service, courteous and kind.

Mike and Tim were fast, efficient and a pleasure to work with! Highly recommend!

I'll add to all of the great reviews here. Mike and his crew did a great job. Mike is the kind of communicator you wish you had for all of your service calls, and he asks all the right questions and handles everything. He delivered on time and on the estimated cost, and working with him was a real bright spot in an otherwise very difficult time. Can't recommend enough. Thank you so much, Mike.

Words cannot express the thanks and gratitude I have for Bio-One of Worcester! Mike and his son came to our aid after one of our cats created for herself a bathroom in a crawl space in our split level home, which also went under the lower staircase. This dynamic duo wasted no time getting everything clean again! They accommodated us on many levels including working in a swelteringly hot airless environment to cleaning up, as well as visiting us three times to make sure the area had responded to the treatments, coupled with the utmost respect and courtesty for our situation! I highly recommend Bio-One and will definitely use them again!

Absolutely five stars for Bio-One! They did an amazing job from start to finish. The team was incredibly friendly, efficient, and caring, making a tough situation so much easier to handle. They were not only helpful and honest, but also incredibly professional in everything they did. What stood out most was their genuine willingness to help and their strong focus on safety and care throughout the entire process. I can’t recommend Bio-One enough—truly top-notch service with heart!

Highly recommend - Prompt, knowledgable, kind and with integrity! Mike at Bio-One came out the same day that I called with a concern about mice droppings in our attic. We have had an exterminator service on hire the past couple years to prevent mice that seem to like our garage and we were quoted upwards of $10k by them to clean out droppings in our attic. I called Bio-One for a second opinion on the clean up. Mike did a thorough evaluation (and climbed into our tiny attic opening!) and provided reassurance that it was not a major issue (barely anything there) and did not require professional management. He was so personable, knowledgable and kind and saved us thousands of dollars with his evaluation. If we ever have a true issue I will absolutely be reaching out to Bio-One again.
