In a carrier member, a connecting fiber connects a peripheral part of an opening of a front surface layer and a peripheral part of an opening of a back surface layer, for each opening. At least one part of at least one connecting fiber is located inside a virtual space. The virtual space is a space which is surrounded with both surface layers and virtual vertical walls. The virtual vertical walls are extended, from inner edges of the peripheral part of the opening of one layer, to the other layer. The carrier member has many opportunities for a volatile component, held by the carrier member, to touch blown air so as to volatilize the volatile component.

Carrier member and support member

The device for dispensing a volatile insecticide or repellent includes a sheet impregnated with an insecticidal/repellent component which volatilizes at an ordinary temperature; a flat box for detachably holding the sheet, the flat box having a sheet-exposing aperture for volatilizing the insecticidal component from the held impregnated sheet; and a suspension cord for three-dimensionally assembling a plurality of the flat box.

2,5-dioxo-3-(2-propynyl)imidazolidin-1-ylmethyl 2,2-dimethyl-3-(alenyl) cyclopropane carboxylate compounds and pesticidal methods and compositions utilizing the same

A pest control device is provided with (1) a volatile substance holder, which includes a pest control component volatilization surface and a liquid volatilization surface, and (2) an indicator, which is composed of a wick and a bottle. The pest control component volatilization surface holds a pest control component volatile at ordinary temperature so that the pest control component can be volatilized into the air, while the liquid volatilization surface is able to hold a liquid volatile so that the liquid can be volatilized into the air. The wick is for supplying the liquid to the liquid volatilization surface of the volatile substance holder, while the bottle contains the liquid to be supplied to the liquid volatilization surface via the wick. In this manner, the indicator indicates how much the pest control component, which is volatilized from the pest control component volatilization surface is left, by showing how much the liquid is left in the bottle.
