COILED INSECT FUMIGANT

摘要

A burnable insect fumigant coil comprises a radially outward, insect control component-containing region linked to an insect control component-containing inner coil which extends radially inwards. The radially outward region has a cross-sectional area greater than the cross-sectional area of the adjacent inner coil. The coil is lit at an outer end and disperses the insect control component at a greater rate when burning through the radially outward region than when it begins burning the inner coil. The coil can be placed in a room or other open or closed environments, lit, and used to repel insects, particularly mosquitoes. The coil is made of inexpensive, environmentally friendly materials, has long life and can be manufactured cheaply. The coil has an enlarged outer portion for providing quick coverage of an insect control component in a space that previously had none. The inner coil portion has a substantially constant, lesser cross-sectional area so that fumigant waste is minimised once the room already has an adequate base concentration of fumigant dispersed in the air.
