Non-toxic pest control compositions and methods and uses thereof
The present specification discloses pest control compositions, articles of manufacture, containers or kits comprising such compositions, and methods and uses to control a population of invertebrate pests from a mammal, location, plant, structure treated of such pest control compositions.
1. A method of controlling a population of invertebrate pests, the method comprising applying an effective amount of a pest control composition to the population of the invertebrate pests and/or one or more locations where control of the population of the invertebrate pests is desired, the composition comprising a treated, fermented yeast supernatant including bio-nutrients, minerals and amino acids, and about 5% to about 15% by weight of one or more nonionic biosurfactants,
wherein the treated, fermented yeast supernatant lacks any active enzymes, activatable pro-enzymes, or any enzymatic activity, and
wherein the composition lacks any active enzymes, activatable pro-enzymes, or any enzymatic activity.
2. The method according to claim 1 , wherein the pest control composition comprises at least 35% by weight of the treated, fermented yeast supernatant.
3. The method according to claim 1 , wherein the pest control composition comprises at most 95% by weight of the treated, fermented yeast supernatant.
4. The method according to claim 1 , wherein the pest control composition comprises at least 6% by weight of the one or more nonionic biosurfactants.
5. The method according to claim 1 , wherein the pest control composition comprises at most 12% by weight of the one or more nonionic biosurfactants.
6. The method according to claim 1 , wherein the pest control composition comprises from about 7% to about 11% by weight of the one or more nonionic biosurfactants.
7. The method according to claim 1 , wherein the pest control composition further comprises one or more anionic biosurfactants.
8. The method according to claim 7 , wherein the pest control composition comprises from about 0.5% to about 10% by weight of the one or more anionic biosurfactants.
9. The method according to claim 8 , wherein the pest control composition comprises from about 1% to about 8% by weight of the one or more anionic biosurfactants.
10. The method according to claim 9 , wherein the pest control composition comprises from about 2% to about 6% by weight of the one or more anionic biosurfactants.
11. The method according to claim 1 , wherein the pH is at most 4.5.
12. The method according to claim 1 , wherein a yeast used in a yeast culture to produce a yeast supernatant used as a source to make the treated, fermented yeast supernatant is from a yeast genus including Brettanomyces, Candida, Cyberlindnera, Cystofilobasidium, Debaryomyces, Dekkera, Fusarium, Geotrichum, Issatchenkia, Kazachstania, Kloeckera, Kluyveromyces, Lecanicillium, Mucor, Neurospora, Pediococcus, Penicillium, Pichia, Rhizopus, Rhodosporidium, Rhodotorula, Saccharomyces, Schizosaccharomyces, Thrichosporon, Torulaspora, Torulopsis, Verticillium, Yarrowia, Zygosaccharomyces , or Zygotorulaspora.
13. The method according to claim 1 , wherein application of the pest control composition causes an adverse effect on the population of the invertebrate pests sought to be controlled.
14. The method according to claim 13 , wherein application of the pest control composition causes at least 10% mortality of the invertebrate pests in the population, causes at least 10% reduction in the size of the population of the invertebrate pests sought to be controlled, and/or deters at least 10% of the invertebrate pests in the population from entering or infesting the one or more locations.
15. The method according to claim 1 , wherein the invertebrate pests comprise an insect, an arachnid or a nematode.
16. The method according to claim 15 , wherein the invertebrate pest includes members in the egg, larval, nymphal, juvenile, pupal, and adult stage of development.
17. The method according to claim 1 , wherein the one or more locations comprises a plant or group of plants or part of a plant, a particular area of land, or a man-made structure.
18. The method according to claim 17 , wherein the particular area of land is a lawn, a garden, a nursery or an agricultural field.
19. The method according to claim 17 , wherein the man-made structure is a commercial building, a residential house, a community facility, a barn, a stable, a shed, a greenhouse or any other physical structure.
20. The method according to claim 1 , wherein the pest control composition is biodegradable.
