Abstract
Description
本発明は、害虫防除用スプレーに関する。 The present invention relates to a pest control spray.
クロチアニジンを殺虫成分とするエアゾールが開発されている（特許文献１）。ゴキブリなどの徘徊性害虫を防除する場合、この類のエアゾールを害虫に直接噴霧して防除する方法が取られている。 An aerosol containing clothianidin as an insecticidal component has been developed (Patent Document 1). When controlling wandering pests such as cockroaches, a method of directly spraying this kind of aerosol on the pests is adopted.
しかしながら、対象となる害虫を視認し、エアゾールやスプレーを直接噴射して防除しようとすると、害虫がソファーや家具などの調度品と床面との隙間に逃げ込んでしまい防除できなくなる状況に陥ることがあった。 However, if the target pest is visually recognized and an attempt is made to control it by directly spraying an aerosol or spray, the pest may escape into the gap between the furniture such as a sofa or furniture and the floor surface, resulting in a situation where the pest cannot be controlled. there were.
そこで本発明者らは、このような状況を防ぐべく検討した結果、屋内害虫の徘徊地域に特定の害虫防除用組成物を噴霧塗布しておくことにより、害虫が当該害虫防除用組成物に接触することで、安定した防除効果を達成できることを見出し本発明に至った。 Therefore, as a result of studies to prevent such a situation, the present inventors have sprayed and applied a specific pest control composition to the wandering area of indoor pests, so that the pests come into contact with the pest control composition. By doing so, it was found that a stable control effect can be achieved, and the present invention has been reached.
