  • the efficacy data including the knockdown percentage (after 30 seconds) and mortality percentage (after 24 hours), was observed for one flying insect (Culex quinquefasciatus) and one crawling insect (Blattella germanica). The results from the efficacy tests are provided in Table 23 below.
  • the testing results showcase optimal propellant amounts that may be used in combination with the formulations of the present disclosure, if an aerosol formulation is desired. Although this testing was only performed for nitrogen, it should be understood that other propellants, including but not limited to, carbon dioxide or hydrocarbons, for example, may also be used in combination with the formulations of the present disclosure.
  • Formulations 47 and 48 were prepared according to the ingredients and weight percentages listed in Table 24. Formulations 47 and 48 are oil-based insecticidal formulations, rather than water-based insecticidal formulations and comprise about
  • Formulations 47 and 48 were tested according to the premises treatment procedures discussed above and the results are summarized in Table 25 below. Overall, the treated test systems exhibited 24-hour mean mortality of greater than 80%, while all untreated test systems exhibited 24-hour mean mortality of less than 10%, thereby exhibiting the efficacy of formulations of the present disclosure. In addition, this efficacy data exhibits the other carriers that may be used in the compositions of the present disclosure, as well as the ability of waterbased compositions to yield comparable efficacy results to oil-based compositions.
  • repellent efficacy data was collected for a formulation having an active component with at least one mint oil and a rosemary oil.
  • the ratio between the at least one mint oil (e.g., spearmint oil) and rosemary oil was kept constant, but the specific weight percentages of the at least one mint oil and rosemary oil was increased to produce a formulation that could be emitted from a device.
  • the number of other active ingredients e.g., sodium lauryl sulfate
  • other inert ingredients e.g., water, glyceryl monooleate, saponin, sodium benzoate
  • the formulation tested included an active component having only one mint oil (i.e., spearmint oil) and rosemary, and the inert component included only a solvent (i.e., ethyl lactate, butyl lactate, or isopropyl alcohol, or propylene carbonate).
  • a dispenser mechanism such as one of the insect repellency devices disclosed in U.S. application Nos. 17/837,110 and 17/878,629, the entire contents of which are incorporated herein by reference.

  • Table 26 Components of Formulation 49.
  • Test plots were constructed including two walls and a flat and level table was placed about 5 ft. from the vertex of the walls. Next, traps were placed around the perimeter of a 6 ft. diameter circle, centralized around the table. More so, two other traps were placed 120 degrees away from the initial trap around the perimeter of the circle.
  • a pre-count period was run for 30 minutes, after which collection bags were removed and replaced with new, collection bags for four intervals. After collection, mosquitos in the collection bags were taken to be counted.
  • Percent repellency versus the untreated control was calculated for each data point (each 30-minute collection over the 2-hour test period). The percent repellency was calculated by adding the number of mosquitos in the three traps at each test plot per time point and comparing that number to the total number of mosquitoes in the three traps of the untreated control plot per time point.
  • embodiments of the present disclosure also provided desired repellency effects. While timepoints at the beginning of the evaluation period showed lower repellency during protection buildup, the overall median percent repellency showed a significant reduction of captured mosquitoes in the treatment zone compared to an untreated area, thereby supporting the premise that the test substance is also effective at repelling mosquitoes.
  • Test #1 had a 6 ft. diameter and a 12/12 duty cycle (i.e., 12 seconds of dispending and 12 seconds not dispensing).

  • Test Site #3 had a 10 ft. diameter and a 12/12 duty cycle.
  • Test Site #4 had a 6 ft. diameter and a 6/18 duty cycle.
  • the embodiments of the present disclosure also provide desired repellency effects when used with dispensing devices. While timepoints and device failures occurred at some instances, the overall percent repellency showed a significant reduction of captured mosquitoes in the treatment zone compared to an untreated area, thereby supporting that the test substance is highly effective at repelling mosquitoes.
