3.4. Control and costs
As predicted, greater facility sanitation correlated with reduced pest control costs between the two facilities (Table 1). Reductions in pest management costs, however, were not the direct result of increased financial investment in sanitation, as Facility B still spent more than Facility A on sanitation. Comparing sanitation expenditures as a function of facility size or as a percent of gross revenue only confirmed Facility B's higher level of expenditures on sanitation.
3.5. Facility attitudes and pest management
Manager responses to attitudinal questions regarding pest management and sanitation displayed a number of differences (Table 2). First, Facility A identified insects entering the facility through cracks and openings as the primary route that insects use to gain entry, while Facility B identified raw grain as the primary route. Second, Facility A reported cleaning exercises and similar actions are direct causes for an increase in the visibility of insect infestations. However, the manager of Facility B reported that he did not know what actions he or his staff could take to increase infestation visibility. Third, each manager was asked to identify different tactics as the best means of controlling or halting insect infestations. Facility A's manager stressed sanitation as the foundation for their pest management program, while Facility B emphasized facility fumigation in controlling pest infestations.
