Description

  The present invention relates to a pest capturing apparatus for underground structures and a pest capturing system using the pest capturing apparatus. As used herein, the term “underground structure” is a generic term for structures such as sewer pipe facilities buried in the ground, piping facilities under road surfaces in waterworks and gas pipes, and underground facilities in electric power and communications. .

  2. Description of the Related Art Conventionally, a technique for installing an insecticide in an underground structure is known as a technique for controlling insects such as cockroaches and mosquitoes that inhabit the underground structure. For example, Patent Document 1 discloses a technique of installing an insecticidal sterilization instrument that exhibits an insecticidal sterilizing function by immersing in water in a water retention part constituted by a rainwater tank or a storage tank. That is, the technique of Patent Document 1 is to extinguish and eliminate pests by eluting an insecticidal sterilizing component in water.

  Thus, the basic idea of the pest control technology in the conventional underground structure is to kill the pests with an insecticide. However, for example, in sewage pipeline facilities, the use of pesticides is regulated by the Sewerage Law, etc., because the components of the pesticides eluted in the sewage cause the microorganisms used in the sewage treatment plant to die. There are places where insecticides cannot be used.
