Strong Water Fastness
①Insecticides were sprayed on tiles (0.5 ml of diluted solution of each insecticide on 100㎠ tile) and those tiles were soaked in water for 8 hours and subsequently stored in a drying machine for 16 hours.
②10 Blattella germanica females were released onto each tile
③The mortality rate of the cockroaches was observed seven days after the release

Long residual efficacy : Lab. study
①Insecticides were sprayed on decorative plywood (0.5 ml of diluted solution of each insecticide on 100㎠ tile) .
②10 Blattella germanica females were released onto each plywood.
③The mortality rate of the cockroaches was observed one day and 3 months after the release

Long residual efficacy : Field
Trial site:Kitchen in a noodle restaurant in Tokyo (24㎡)
Application method:Surface residual spray (50 ml/㎡)

Low Lethal Dose for Insects
①10 Blattella germanica (♀5 + ♂5) were made to contact pesticide residue for 1 hour
②The treated cockroaches from step 1 were released into a box which had 30 untreated cockroaches (♀15 + ♂15)
③Seven days after the release of the treated cockroaches, the mortality rate of the untreated cockroaches in step 2 was observed.
①A piece of plywood was sprayed with an insecticide. (The tested insecticides are BROBUSTER™ 5 SC and Cyphenothrin 5%EC.)
②After the plywood was dried, 10♀＋10♂ cockroaches were released into the box in which the sprayed plywood and a piece of non-treated plywood had already been placed as shown in the picture.
③Three days after the cockroaches were released, the mortality rate of the cockroaches was observed.
