About Us

Serving Massachusetts with Expert Pest Control Since 1985

Dennis the Mennis Pest Control has been a trusted name in pest control services throughout Massachusetts and surrounding communities for over five decades. Established in 1985, our company has built a reputation for delivering reliable, professional, and effective pest removal solutions for both residential and commercial clients.

We proudly serve homeowners and businesses throughout Massachusetts—including Boston, Cambridge, and surrounding towns—as well as Southern New Hampshire. Our mission is simple: provide honest, high-quality pest control backed by real experience and proven results.

Why Experience Matters in Pest Control

Pest control is not a one-size-fits-all service. Every infestation is different, and improper treatment can make the problem worse.


With decades of experience, we know how to:


  • Accurately identify pest types and infestation sources
  • Apply targeted treatments that work the first time
  • Prevent future infestations through proven strategies
  • Protect your property without unnecessary disruption



Whether it’s a small residential issue or a large commercial infestation, our team delivers solutions you can depend on.

A Company Built on Experience and Trust

What sets Dennis the Mennis Pest Control apart is our deep industry experience. Every technician on our team brings a minimum of 15 years of hands-on expertise, with many having over 30 years in the field.


That means when you call us, you’re not getting a temporary or seasonal worker—you’re getting a seasoned professional who understands pest behavior, proper treatment methods, and long-term prevention strategies.


Mr. James Duffy has been recognized as a Top Technician in America in 2004, 2011, and again in 2024, reflecting the high standards and expertise we bring to every job. We strive to earn our clients’ recommendations to their family and friends without reservation.
