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).

A topical insect repellent with extended duration of protection was obtained from mixtures of molecules based on two or more volatile repellent organic molecular species occurring naturally on the human skin surface. The novel repellent comprises mixtures of lower, intermediate, and higher volatility organic molecules. Active ingredients for formulations are obtained from homologous series of carboxylic acids, alcohols, ketones, and lactones which span a similar range of volatility and which occur naturally on the skin surface. Volatile silicone fluid imparts mildness and water repellency to the repellent formulations. The new natural repellent exhibits the longevity and repellency that is comparable to N,N-diethyl-m-toluamide (DEET), a synthetic compound employed in almost all commercial formulations, but the inventive natural repellent is more acceptable than DEET, which has an unpleasant odor and imparts a greasy feel to the skin. The inventive insect repellent, formulated in a volatile silicone fluid, was shown to repel and incapacitate stable flies. This finding demonstrated that repellency was not limited to mosquitoes, but extends to other biting flies or insects, thus demonstrating the utility of the novel insect repellent for protecting pets and livestock as well as humans.

The present invention provides for, inter alia, novel topical formulations comprising at least one 1-N-arypyrazole derivative and amitraz and to methods for treating, controlling, or preventing parasite infestations on mammals or birds The inventive formulations include spot-on, pour-on or spray formulations and may include a further ectoparasiticide, such as an IGR compound, an avermectin or milbemycin derivative, or a pyrethroid insecticides, and anthelmintics, such as benzimidazoles and imidazothiazoles. The inventive formulation provides a larger duration of parasite control at a faster rate of control. The inventive formula remains effective up to three months from the first application. Moreover, the inventive formulations prevent tick attachment to the animal, thereby providing protection against tick borne diseases. The ectoparasites which may be controlled, treated or prevented by the present invention includes ticks, fleas, mites, mange, lice, mosquitoes, flies and cattle grubs.

A drone with a high-voltage trap seeks, identifies, pursues and destroys flying insects within a patrolling area. During its passive attracting mode, the drone lands on a designated ground site and attracts insects with light, sound, and scents. Once insects are lured, the high voltage screens trap will immediately electrocute targeted insects. In its active offensive mode, the drone hovers closer to insect nests using its high-velocity propellers, producing strong downdraft jet streams to disturb the nest and force insects, such as mosquitoes and the like, to evacuate their nest. Once insects are airborne, the drone pursues fleeing insects from below or behind, making use of its propellers and vacuuming the fleeing insects. Slow flying insects that come in contact with the high-voltage electrified screens are immediately electrocuted. Insects that are vacuumed into the fast-spinning propellers blades are knocked down and killed. A rectified charging pad recharges the drone batteries.

An apparatus for attracting mosquitoes to an electronic insect killing machine (i.e., bug zapper) is provided. The apparatus includes a converter device that fits over a fluorescent or ultraviolet light bulb of the bug zapper. The converter device controls radiant light and heat emitted by the light bulb to produce a desired level of heat to create a warm mass, or host simulator that simulates a blood host meal for biting insects. Mosquitoes and other biting insects, which have infrared vision, are attracted to the host simulator. When used with a scented lure that lures the mosquitoes and biting insects near the insect killer, the host simulator lures the mosquitoes and other insects to the killing device of the insect killer. The mosquitoes and biting insects are destroyed once lured to the killing device. The converter device also blocks most of the visible light emitted by the light bulb, and therefore does not lure beneficial insects, which are attracted to visible light, into the insect killer.
