Abstract: The invention relates to a method for attracting flying insects, particularly mosquitoes, for the purpose of trapping or killing them, which comprises releasing at least one chemical attractant for the insects including carbon dioxide, by reacting with water or other aqueous medium, a mixture of ingredients (such as sugar and yeast) which has previously been maintained in a substantially oxygen-free environment and which have the ability to interact with each other in presence of water or other aqueous medium, so as to generate the at least one chemical attractant. The invention also includes an essentially air-proof sealed package containing a mixture, substantially free of contact with oxygen, of the type described; the mixture also constitutes per se, an aspect of the invention.

Abstract: A device and method for trapping flying insects including a housing having an opening for the entry of insects; a physical attractant for the insects; a trapping arrangement arranged in association with the physical attractant for trapping insects attracted thereto; and an emission arrangement for emitting a chemical attractant for the insects employing a cartridge which contains predetermined amounts of preselected chemical reactants and which engages the trapping device so that the cartridge is operative to enable the emission arrangement to produce a gaseous suspension of the chemical attractant in the vicinity of the trapping device.

Abstract: A method and a device (10) for trapping insects which feed on mammalian blood, such as mosquitoes, utilize in combination a chemical attractant (24) and a physical attractant consisting of a dark panel (22), heated to e.g., 30 to 45 degrees Celsius. The chemical attractant may include carbon dioxide, generated for example by action of microorganisms on a fermentable substrate in aqueous medium, or it may be selected from fermenting yeast, yeast extract, peptone, acetone, lactic acid and carbon dioxide. The insects may be killed by adhesive applied onto the panel (22).
