Rebecca's son-in-law, Homer McDaniel became an employee of International Exterminator in 1925 as a residential and commercial pest control technician. After the original owner became ill, Homer became the General Manager in 1930 and eventually bought the business. He managed the (now successful) business until 1943 when he passed away and his wife, Florence McDaniel, and son, Jim McDaniel, took over the business. Jim (3rd generation) was the primary owner until his brother, Wayne McDaniel joined him after his tour during the Korean War. Jim's wife, Dorothy, and Wayne's wife, Dolores both joined as part of the International Exterminator office staff.
In 1965, Jim's son, Patrick McDaniel (fourth generation) came to work for International Exterminator. At that time, minimum wage was as low as $2 per hour and gas was all the way down to 30 cents per gallon! Eventually, in 1985, Pat became the General Manager of International Exterminator. Thomas Horton, Patrick's brother-in-law, started working as a technician in 1974 and eventually became Service Supervisor.
