Abstract
Control or repellency of biting arthropods, particularly biting insects, is accomplished by bringing the biting arthropods into contact with combinations of compounds identical or related to those found on human/animal skin or in plants acting synergistically with one another, or in combination with conventional repellents like N,N-diethyl-3-methylbenzamide (DEET®), para-menthane-3,8-diol (PMD), sec-butyl-2-(2-hydroxyethyl) piperidine carboxylate (“Picaridin”), or other nitrogen containing repellents selected from amines, amides and nitrogen containing heterocyclic compounds, or any synergistic combination of DEET®, PMD, Picaridin, or other nitrogen containing repellents selected from amines, amides and nitrogen containing heterocyclic compounds.
Claims22
A method for the repellency of biting arthropods, the method comprising bringing the biting arthropods into contact with a synergistic biting arthropod repellent formulation, wherein the synergistic biting arthropod formulation consists essentially of:
- (I) any synergistic combination of two or more compounds (a), wherein compounds (a) are selected from the group consisting of methyl dihydrojasmolate, propyl dihydrojasmolate, methyl dihydrojasmonate, propyl dihydrojasmonate, delta-dodecalactone, gamma-dodecalactone, apritone, methyl apritone, and lactic acid;
- or
- (II) any synergistic combination of one or more of the compounds (a) with one or more repellents selected from the group consisting of N,N-diethyl-3-methylbenzamide (DEET®), para-menthane-3,8-diol (PMD), 1-(1-methylpropoxycarbonyl)-2-(2-hydroxyethyl)piperidine (Picaridin), and ethyl butylacetylaminopropionate (IR3535®);
- wherein the synergistic combination of two or more compounds (a) is present in an amount from about 0.5% by weight to about 20% by weight, based on the total weight of the synergistic biting arthropod repellent formulation;
- and wherein the synergistic combination of one or more of the compounds (a) with one or more of the repellents is present in an amount from about 0.5% by weight to about 20% by weight, based on the total weight of the synergistic biting arthropod repellent formulation;
- wherein the biting arthropods are selected from the group consisting of mosquitoes, bed bugs, biting flies, ticks, and biting midges;
- wherein the synergistic combination consisting essentially of a combination of two or more compounds (a) of (I) or a combination of one or more compounds (a) and one or more repellants of (II) produces, when biting arthropods are brought into contact with the synergistic formulation, a combined repellency effect, greater than the sum of the separate repellency effects, at essentially the same concentrations.

- and wherein the synergistic combination of one or more of the compounds (a) with one or more of the repellents is present in an amount from about 0.5% by weight to about 20% by weight, based on the total weight of the synergistic biting arthropod repellent formulation;
- wherein the biting arthropods are selected from the group consisting of mosquitoes, bed bugs, biting flies, ticks, and biting midges;
- wherein the synergistic combination consisting essentially of a combination of two or more compounds (a) of (I) or a combination of one or more compounds (a) and one or more repellants of (II) produces, when biting arthropods are brought into contact with the synergistic formulation, a combined repellency effect, greater than the sum of the separate repellency effects, at essentially the same concentrations.
