PROBLEM TO BE SOLVED: To prevent the parasitism of fleas or acari on pets by killing the flea or acari living in a grassy ground, making a contact with or attaching to the lower extremities of the pets in walking and then moving upward to the upper body, by making a contact with an insecticidal component transpirable in normal temperatures at a part of the insecticidal foot ring attached as covering the lower extremity to exterminate the insects at the same time with the contact or within a short time thereafter.SOLUTION: This tubular flexible foot ring for the pet, the inside of which tubular part is penetrated with the lower extremity of the pet, wearable so as to partially cover the extremity is constituted by a flexible material containing an insecticide/insect repellent. The inner circumference at the non-wearing time is almost equivalent to or shorter than the outer circumferential length of the lower extremity of the pet at the wearing time, and stretches in circumferential direction so as to be capable of penetrating the lower extremity of the pet through the inside of the tube when it is worn.COPYRIGHT: (C)2008,JPO&INPIT【課題】草地内などに棲息しているノミやダニなどが、散歩中のペット類の下脚部に接触ないしは取り付いて上体に移動しようとする際に、下脚部を包み込むように装着した防虫足輪の部分で常温蒸散性の殺虫成分と接触するため、接触と同時あるいはその後の短時間内に死滅させることができ、ペット類へのノミやダニなどの寄生を防止することができる。【解決手段】筒内をペットの下脚部が貫挿されて該下脚部を部分的に包み込むように装着可能な筒状の伸縮性ペット用防虫足輪であって、該ペット用足輪は殺虫・防虫剤含有の伸縮性材料から構成され、非装着時の内周が装着時におけるペットの下脚部の装着部の外周長さとほぼ同等ないしはそれより短く、装着の際にはペット下脚部が筒内を貫挿可能に円周方向に伸張してなることを特徴とする伸縮性ペット用防虫足輪。【選択図】図4
