A long life mat impregnated with insect repellant is provided which has greater concentration that prior art mats in the area above a heated sole plate in prior art volatilizable insecticide repellant devices.

An assembly for evaporating a volatile fluid is described, the assembly comprising a device and a refill which are detachable from one another: wherein the device comprises a magnetic induction coil configured to operate with an alternating current passed therethrough; and wherein the refill comprises a reservoir for the volatile fluid, a volatile fluid transport means to draw the fluid from the reservoir, and at least one susceptor arranged to heat the volatile fluid transport means when said alternating current is passed through the induction coil. Refills, devices and methods of operation are also described.

An assembly for evaporating a volatile material is described, the assembly comprising a device and a refill which are detachable from one another: wherein the device comprises a magnetic induction coil configured to operate with an alternating current passed therethrough at a frequency of between substantially 20 KHz to substantially 500 KHz and one or more volatile fluid emanation channels containing at least one piece of heat-conducting, non-magnetic metal foil and/or deposited heat-conducting, non-magnetic metal; and wherein the refill comprises at least one magnetic susceptor having a coercivity of substantially 50 ampere/meter (H.sub.C) to substantially 1500 ampere/meter (H.sub.C) and a substantially liquid-tight sealed reservoir containing the volatile material; wherein, in use, the magnetic susceptor(s) is arranged to heat the material predominately by magnetic hysteresis when the magnetic susceptor(s) is at least partially positioned in the induced magnetic field generated, in use, when said alternating current is passed through the induction coil. Refills, devices and methods of use are also described.

The present invention provides a heating transpiration composition having an excellent efficacy on exterminating harmful arthropods, which comprises a natural pyrethrin and a pyrethroid compound, wherein the weight ratio of active ingredients of the natural pyrethrin relative to the pyrethroid compound is within the range of 20:1 to 200:1.

An insect repellent system includes an active insect repellent ingredient and a glycol solvent as part of a thermally activated dispersion using a wick and a heater. The active ingredient may be a pyrethroid insecticide or a natural insect repellent material. The glycol solvent includes at least two hydroxyl groups and may be a mixture of glycol solvents. In one solvent mixture, a combination of hexylene glycol and dipropylene glycol are combined with a pyrethroid insecticide of either metofluthrin or transfluthrin. The insect repellent system may be a portable insect repellent system formed from thermoplastic materials and rely on battery power to generate heat.
