The blends contain, in a synergistic combinations, at least two ingredients such as Lilac Flower Oil, D-Limonene, Thyme Oil, Lime Oil, Black Seed Oil, Wintergreen Oil, Linalool, Tetrahydrolinalool, Vanillin, Isopropyl myristate, Piperonal (aldehyde), Geraniol, Geraniol 60, Triethyl Citrate, and Methyl Salicylate.

Claims (13)

1. A pest control blend, comprising, in a synergistic combination, Thyme Oil, Wintergreen Oil, and Isopropyl myristate, wherein the concentration of Thyme Oil is between 15% and 25%; the concentration of Wintergreen Oil is between 40% and 50%; and the concentration of Isopropyl myristate is between 30% and 40%.

2. The pest control blend of claim 1 , wherein the concentration of Thyme Oil is 20.6%; the concentration of Wintergreen Oil is 45.1%; and the concentration of Isopropyl myristate is 34.3%.

3. The pest control blend of claim 1 , having a coefficient of synergy of at least 1.5 for each active ingredient, as measured by a test on a target organism, wherein the test is selected from: knockdown time, killing time, repellency, and residual effectiveness.

4. The pest control blend of claim 3 , having a coefficient of synergy of at least 5 for at least one active ingredient.

5. The pest control blend of claim 4 having a coefficient of synergy of at least 10 for at least one active ingredient.

6. The pest control blend of claim 5 , having a coefficient of synergy of at least 25 for at least one active ingredient.

7. The pest control blend of claim 1 , wherein exposure to the blend disrupts cellular calcium levels within a target organism.

8. The pest control blend of claim 7 , wherein exposure to the blend disrupts cyclic AMP levels within cells of the target organism.

9. The pest control blend of claim 7 , wherein exposure to the blend results in binding of a receptor of the olfactory cascade of the target organism.

10. The pest control blend of claim 9 , wherein one or more components of the blend act as an agonist or antagonist on the receptor of the target organism.

11. A pest control formulation, comprising the blend of claim 1 .

12. The pest control formulation of claim 11 , further comprising at least one ingredient selected from the group consisting of: Hercolyn D, Mineral Oil, Soy Bean Oil, Piperonyl Alcohol, Ethyl Linalool, Hedione, Dipropylene glycol, Citral, gamma-terpinene, Sodium Lauryl Sulfate, Thymol, Alpha-Pinene, alpha-Terpineol, Terpinolene, Para-Cymene, Trans-Anethole, Linalyl Acetate, Beta Pinene, Camphor Dextro, Terpinene-4-ol, Span 80, Tween 80, Potassium Sorbate, Sodium Benzoate, Isopar M, BHA, BHT, dl-alpha-tocopherol lineaolate, Alpha Terpinene, Borneol L, Camphene, Decanal, Dodecanal, Fenchol Alpha, Geranyl Acetate, Isoborneol, 2-Methyl 1,3-cyclohexadiene, Myrcene, Nonanal, Octanal, Polyglycerol-4-oleate, Tocopherol Gamma Tenox, Xanthan Gum, A45 Propellent, Lecithin, a propellent, water, a surfactant, a cationic agent, Sodium Benzoate, Xanthan, and Ksorbate.

13. A pest control blend, comprising, in a synergistic combination, thyme oil, wintergreen oil and isopropyl myristate, wherein thyme oil : wintergreen oil : isopropyl myristate occurs in a concentration ratio of 1:2.19:1.67.
