Lots were sprayed every 21 days. At 17 fixed locations (13 treatment, four control), Centers for Disease Control and Prevention (CDC) CO2-baited traps were deployed overnight, once/week. Oviposition traps were also deployed weekly and remained for seven days to measure Aedes albopictus abundance. Mosquitoes were identified to species and tabulated by location and week. Adult and egg abundance was generally significantly higher in control versus treatment traps. The abundance of Psorophora columbiae and Ae. vexans was significantly higher in control versus treatment traps. Bifenthrin and deltamethrin showed differences in efficacy (e.g. Ae. vexans, An. punctipennis, and Ps. ferox abundance was higher in bifenthrin traps compared to deltamethrin and control traps), but this varied across neighborhoods and species.en-USBarrier SpraysNuisance mosquitoesInsecticide/TermiticidePoster
