Aerosol formulation 75 in the center of the floor (8m, height 1.8m)
Was installed, and the entire amount of the content was injected upward (about 17
Seconds). The actual weight of the sprayed aerosol can was confirmed by measuring the weight of the entire aerosol can before and after the spraying operation and measuring the amount of decrease. The test chamber was closed for 1 hour after spraying, and then the exhaust fan was operated for 10 minutes for forced ventilation. Close the test chamber again,
One day later, forced ventilation was performed for 10 minutes, and after that, the door of the entrance and exit was closed, and at the same time, the adult housefly 5
0 animals were released into the test room, the test room was sealed, and the number of knockdown insects was observed at predetermined time intervals. Further, ventilation was performed for 10 minutes even after 2 days and 3 days. After 3 days, the same housefly knockdown test as that after 1 day was performed. However, the observation time was 30 minutes and 60 minutes, respectively.
