TREATMENT OUTCOME. Successive inspections and treatments produced a slow but steady decline in bed bug numbers (see Figure 1). In 12 of the 15 apartments, live bed bugs could no longer be found 20 weeks (about five months) after initiation of treatment. Three apartments continued to have bed bugs (25, 39 and 59 adults and nymphs) beyond this period, although treatment in these units was hampered by excess clutter, lack of preparation and overall poor tenant cooperation. Compared to the total initial number of bed bugs found in the 15 apartments (2,719), a 78 percent overall reduction was observed after four weeks, 87 percent fewer bugs were found after eight weeks and 96 percent fewer after 12 weeks. However at the four, eight and 12-week evaluations, 14, 11 and 10 apartments, respectively, continued to have some live bed bugs. The seven apartments that received a follow-up inspection two weeks after initial treatment exhibited only a 49 percent overall decline at that time in bed bug numbers — further reinforcing the delayed action of the compound under field conditions. As is often the case with bed bugs, apartments with low-level infestations tended to be more efficiently managed than infestations that were severe.
