The pest control device according to the present invention is provided by holding the above- described drug holding member in an air-ventilative member made of polyethylene terephthalate .
Such an air-ventilative member is made from polyethylene terephthalate (PET) , and so long as it is ventilable to air and capable of housing the drug holding member, its form is not especially restricted. Further, while the air-ventilative member may be completely made from polyethylene terephthalate; a laminate wherein only the portion of the air- ventilative member in contact with the drug holding member, the surface of the air-ventilative member facing the drug holding member or both are made of a polyethylene terephthalate layer can also be used.
The air-ventilative member made from polyethylene terephthalate used in the present invention can be obtained as a molded article by, for example, press-molding a sheet composed of polyethylene terephthalate, or by kneading pellets of polyethylene terephthalate then molding the resultant mixture by injection molding or extrusion molding. The obtained molded article may be further subjected to an arbitrary process by secondary processing. Further, the air-ventilative member made of polyethylene terephthalate used in the present invention may be composed of two or more parts, such as a dish-shaped part having an opening on its bottom and a film-like part. In such case, the pest control device according to the present invention can be made by housing the drug holding member in the concave potion of the dish-shaped part and then covering the top portion thereof with the film-like part. The dish- shaped part and the film-like part can in such case be either a polyethylene terephthalate single layered body, or may be in a form such that just the portion in contact with and/or the entire surface facing the drug holding member is made of a polyethylene terephthalate layer by using a laminate wherein at least one of the surfaces in contact with the drug holding member is made of a polyethylene terephthalate layer.
The pest control device according to the present invention has the above-described drug holding member housed in the above-described air-ventilative member made of polyethylene terephthalate. In addition to housing between the above-described dish-shaped part and film part, the housing method is not particularly limited so long as being housed so that the state wherein the drug holding member is supported in the air-ventilative member can be maintained. Further, the air-ventilative member may be provided with a hanging support . The pest control device according to the present invention is used by installing it as is in pests ' habitats and/or places where pests encroach or the like. The dosage of the pest control device according to the present invention usually ranges from 10 to 500 mg, and preferably 50 to 300 mg, of the ester compound of the present invention per 1 m3 of the locus to be pest-controlled.
Methods for controlling pests using the pest control device according to the present invention include putting it on the floor of the space to be controlled, hanging it from the ceiling, a post or supporting column, or sticking it on a wall. At the installation location of the pest control device of the present invention, the ester compound of the present invention is gradually emitted from the pest control device of the present invention and exerts a pest controlling effect. Examples of installation locations include livestock sheds such as a stable, a cowshed, a poultry house and a pigpen; pet houses such as a kennel and a rabbit hutch; places surrounding the doors, exhaust ports, electric lights and the like of a factory or a workshop; the outside of a house such as a balcony and a porch; storage spaces for clothes, such as the inside of a closet, the inside of a chest of drawers (Japanese and Western) and a standing closet; the interior spaces of a house such as a bedroom, a living room and a kitchen; the inside of a septic tank; the back of a manhole cover,- the exit, periphery and inside of a tent in a camping area or a park,- and places for outdoor activity such as barbecue, fishing, hiking, gardening and the like, and their surroundings.
