The United States' entry into World War II in 1941 posed challenges to Orkin in the form of shortages of personnel, chemicals and supplies. In the particular face of personnel shortages, Ted Oser worked with the National Pest Control Association founder, Bill Buettner, to meet with legislators, rationing boards, and other government agencies to convince them to classify pest control as an "essential service" during the war. Such classification would afford Orkin (and other pest control companies) draft deferments and placement on a preference list to receive chemicals and supplies such as gasoline, tires, and food ration points to manufacture rat bait. Pest control became one of only two service industries operating during the war to be declared as "essential"—the other was mortuary service. The war also caused a growth in the number of military contracts that Orkin took on—the company had over 150 military establishments under contract for regular bed bug fumigations and pest control, and many railroads maintained around-the-clock service agreements that had Orkin pest control teams sleeping in shifts on cots in the rail yards. Pest control services for homes and businesses also remained in demand on top of all of the additional wartime service that Orkin was providing. This overall increase in demand strained the company's resources, particularly since the chemicals that were most readily available for pest control were not as effective and required more frequent treatments, which taxed the already limited workforce. In order to maximize resources, many branch offices were consolidated, some accounts were serviced less often, and service providers traveled further and more often. Despite wartime shortages, however, Orkin not only survived, but it actually grew. In 1945, the company had record gross sales of $2.098 million (equivalent to $ in ) and maintained 82 branches in 14 states.
