ABSTRACT:
In order to keep flying insects, especially mosquitoes, away from people, an apparatus has been developed. The apparatus includes a box (A, A") enclosing a heat source (10, 50), provided with at least one vertically oriented flat wall (13', 53'), and a container (C, C') holding an evaporable liquid chemical product. A wick (14, 54), wrapped in an impermeable coating or sheath (19, 59), has a rectangular cross-section and penetrates inside the container (C, C'). A free portion (14", 54") of the wick (14, 54) is devoid of the coating or sheath (19, 59) and extends upwards from the container (C, C') with its largest side (14"', 54"') being disposed parallel to but spaced from the heat source (10, 50). Inside the container (C, C'), the entire length (L) of the wick (14, 54) is surrounded by the coating or sheath (19, 59), except for the extreme lower free portion (14', 54') into which the liquid is absorbed and rises exclusively by capillarity to the far upper free portion (14", 54"), where the wick (14, 54) is heated by the heat source (10, 50) so that the liquid evaporates and passes into atmosphere.
