PURPOSE: To extirpate ticks and fine insects and prevent noises, by arranging a motor-driven impeller in a suction way connecting to the filter of a vacuum cleaner and fitting a sound-absorber at the internal face of the casing in the periphery of the impeller.

CONSTITUTION: A motor 18-driven impeller 19 is arranged in a suction way connecting to the filter of a vacuum cleaner. And, a sound-absorbing material made of porous urethane foam is fitted at the internal face of the casing 12, 13 in the periphery of the impeller 19. That is, ticks are extirpated by the mechanical impulse due to the centrifugal air flow generated through impeller and also noises incurred by the extirpating device are absorbed in the sound- absorbing material.
