PROBLEM TO BE SOLVED: To provide a creeping hygiene pest control device which prevents leakage of liquid from the inside of the device in association with tipping-over or an increase in room temperature.SOLUTION: A pest control device in this invention includes a bottle part for housing liquid and a liquid suction part for sucking out the liquid housed inside the bottle part to the outside of the bottle part. The liquid suction part includes a liquid suction core and a sheath which wraps the liquid suction core to keep a contact area between the liquid suction core and the liquid constant. A plug part making close contact with a first opening part provided on an upper surface part of the bottle part is provided on an end part of the sheath. The liquid is an aqueous bait agent for creeping hygiene pest control. A second opening part is provided on the upper surface part or on the plug part of the bottle part. An air-permeable liquid sealing part for sealing the liquid inside the bottle part covers the second opening part.
