PEST CONTROL METHOD AND WATER STORAGE-DRAINAGE SYSTEM EQUIPPED WITH CONTROL AGENT

摘要

[Problem] To provide a method whereby pests laying eggs in water, for example mosquito larvae, can be easily and continuously controlled without causing environmental pollution, and a water storage-drainage system.[Solution] As the results of intensive studies to solve the aforesaid problem, the present inventors found that the growth of aquatic pests such as mosquito larvae can be inhibited and these pests can be controlled by placing a molded resin article, which contains a soluble glass capable of releasing silver ions in water with the passage of time or a silver-substituted inorganic ion exchanger, in a pool of water or an area where water likely pools, such a pool of water being a potential nursery of the aquatic pests, e.g., mosquito larvae, thereby completing the present invention.
