Pest removal #921159

Asked October 31, 2025, 11:35 AM EDT

We have a distinct odor in our basement that smells like rotting brocolli for about 2 weeks. Probably a dead mouse but we cannot find it. Our basement is pretty clean. Can you recommend any company that can help us. We have called most pest companies. They don’t handle anything like this. Any suggestions are appreciated.

Hello Kathryn,

Thank you for reaching out to the UNH Extension Infoline.  We cannot recommend any specific company, sorry. 

The following website discusses licensing of businesses for such purposes: https://extension.unh.edu/resource/pesticide-licensing-new-hampshire

The New Hampshire Department of Agriculture has the licensing program for NH:https://www.agriculture.nh.gov/divisions/pesticide-control/licensing.htm

New Hampshire Fish and Game also has a license for trapping. Some trappers maybe able to help you: https://www.wildlife.nh.gov/hunting-nh/trapping

This UNH website explains how to prevent mice from entering the home: https://extension.unh.edu/blog/2018/10/how-can-i-get-rid-mice-my-house

The Better Business bureau has recommendations for licensed pest control servicers :  https://www.bbb.org/us/nh/manchester/category/pest-control/accredited

I hope this information is helpful! Please feel free to reach out with any further questions!
