Mack Pest Control, Inc. started as a one man operation in 1944, by C.C. (Mack) McKelvey. He first become acquainted with the pest control industry by responding to an ad in a magazine about business opportunities. He sent off his money and received a booklet about controlling pests, along with a hand duster and some dust pesticide.

From that beginning, he began to “kill roaches and rodents”. He knocked on doors and started demonstrating his pest control skills for cash. “Mack the Bug Man” began to be known in the Nashville area and he soon needed help! In 1952, the company was incorporated and Mack added a business partner, A. B. Oliphant. During these years, routes were developed in the Nashville area and also the surrounding towns. In 1977, an office was opened in Jackson, TN and from there an office was opened in Memphis, TN in 1988.

At C.C. McKelvey’s death, Lloyd McKelvey and A. B. Oliphant, Jr. were the owners of the company. Tom Swint, Sr. became a partner of Lloyd’s in early 1970’s and they continue as owners of the company.

Tom and Lloyd have worked together in the business since 1958. Lloyd finished a degree in Entomology from Auburn University in August 1958. Together they have led the company in its advancement through the years. Together, Lloyd and Tom have over a 100 years experience with Mack Pest Control and both remain active in the business.

Tommy Swint, Jr., Tom’s son, having worked as a young man in the business went on to the University of Kentucky to receive his degree in Entomology in 1986. He along with Tom Senior oversees the Nashville Office and surrounding areas.
