Studies highlight its ability to penetrate insect exoskeletons and impair critical functions, resulting in high mortality rates upon contact. These findings are supported by extensive testing detailed in Cornell University studies.

    • Mosquito control: Functions as a powerful larvicide, with research indicating significant effectiveness against mosquito larvae, including those of Anopheles stephensi and Aedes aegypti.
    • Houseflies and aphids: Demonstrates potent toxic effects on houseflies and is an effective control against aphids, impacting their survival and ability to thrive on treated plants.
    • Agricultural pests: Shown to reduce larval feeding and survival rates in pests like the Colorado potato beetle, providing a natural solution for agricultural pest management.
    • Storage pests: Proven to manage post-harvest pests such as red flour beetles and pulse beetles.

      Targeted application: Target specific pest entry points with Dr. Killigan's Dust to Dust Plant-Powered Insect Powder, infused with peppermint oil.

      Dual action efficacy of clove oil: Clove oil repels and kills pests on contact. According to research from Cornell University, clove oil is highlighted for its ability to cause high mortality rates among various insects, including those resistant to other treatments. This robust efficacy makes it an essential tool for natural pest control.

      Clove oil
      • Mosquito control: Effective as a repellent, clove oil has shown extended duration of activity against mosquitoes, including Aedes aegypti and Anopheles dirus, preventing bites for up to several hours.
      • Termites and mites: Proven highly toxic to termites and mites, clove oil causes 100% mortality in certain species within days.
      • Agricultural and storage pest management: Clove oil is effective against the Colorado potato beetle, the red flour beetle and the pulse beetle. It reduces larval feeding and survival significantly, offering a natural alternative to chemical pesticides in both fields and storage settings.
      • Stink bugs and vespids: Clove oil has been used successfully in traps to repel over 95% of brown marmorated stink bugs and effectively block the attraction of vespid wasps.

        • Storage and agricultural pest management: Cinnamon oil exhibits strong activity against various storage pests like the rice weevil (Sitophilus oryzae) and the bean weevil (Acanthoscelides obtectus), and agricultural pests including the cecidomyiid gall midge, which is a pest of shiitake mushrooms. It is particularly noted for reducing the reproduction and survival of these pests when applied directly to stored products or crops.
