In addition, a control device (39) is provided, by means of which the electrical heating device (30) can be controlled, preferably at intervals.

An evaporator (1) comprises a housing (2) having a top wall (7) in which a receiving recess (14) is formed for receiving a container (15) for a liquid to be evaporated. A heat transfer element (30) having a first heat transfer abutment face (35) located in the receiving recess (14) transfers heat from an electrically powered heating element (25) to the container (15) through a second heat transfer abutment face (36) of a base (16) of the container (15). The heating element is planar and is located between the heat transfer element (30) and a locating element (40), which retains the heating element (25) tightly between the heat transfer element (30) and the locating element (40). A retaining magnet (48) located in the locating element (40) extends into a bore (52) in the heat transfer element (30) and co-operates with a complementary element (49) of magnetic material located in the base (16) of the container (15) for releasably retaining the container (15) in the receiving recess (14).

An insect pest control product applicable to a water-based insecticidal composition with stable performance over a long time, which comprises a thermal vaporization/diffusion absorbent wick for vaporizing and diffusing a water-based insecticidal composition containing a pyrethroid insecticidal component having a vapor pressure of 210.sup.4 to 110.sup.2 mmHg at 30 C., a glycol ether compound having a boiling point of 150-300 C., and water. The wick has a water/oil-based liquid absorption ratio (V.sub.1/V.sub.2) within the range of 0.55-1.0, calculated from a speed (V.sub.1) at which a water-based liquid formulation rises through the wick, and a speed (V.sub.2) at which an oil-based liquid formulation rises through the wick, the water-based liquid formulation contains 40 mass % of diethylene glycol monobutyl ether, and the oil-based liquid formulation is a fluid paraffin having 14 carbon atoms.

A volatile composition dispenser and a method of dispensing a volatile composition is provided. The volatile composition dispenser includes a reservoir for containing a volatile composition and a transport member having a first end portion and an opposing second end portion, and an evaporative surface.
