Sheehan was the founder of Checkmate Exterminators, which he owned and operated for 27 years before selling it to Terminix International in 1998. He was also the co-host of the Colony Confidential podcast, one of the longest-running podcasts in the pest control industry. He was joined on the podcast by his son, Joseph, who is CEO of Colony Pest Management, a Brooklyn, N.Y.-based pest control company.
Through his decades of service, Sheehan didn’t just build a business — he built a community. The podcast gave him a platform to share insights, experiences and opinions during conversations laced with love, respect and humor.
“His voice on Colony Confidential wasn’t just informative — it was personal, real and unmistakably Ed. He elevated the pest management profession by making it approachable and respected, always blending expertise with a unique brand of New York charm,” the Colony Confidential team shared in a statement.
Sheehan also made an on-screen appearance in Morgan Spurlock’s documentary, “RATS.” The documentary took a look at the history of rat infestations in major cities throughout the world.
In the wake of the news, The Edward J Sheehan scholarship fund has been created to honor Sheehan’s legacy in the industry.
