Total Claims: 7
Claim 1
Independent Claim
55 words
Method of controlling cockroaches, comprising the step of irradiating said cockroaches with discontinuous ultraviolet rays, said irradiating being alternately on and off for 15 minutes each, for a total time of from 9 to 96 hours, and wherein said ultraviolet rays have wavelengths toward the longer wavelengths in the ultraviolet band and below 291 nm.
Claim 2
Dependent Claim
55 words
Method of controlling cockroaches, comprising the step of irradiating said cockroaches with discontinuous ultraviolet rays, said irradiating being alternately on and off for 15 minutes each, for a total time of from 9 to 96 hours, and wherein said ultraviolet rays have wavelengths toward the longer wavelengths in the ultraviolet band and below 291 nm.
