Are you ready to turn over a new leaf in pest control? Let's dive into the world of plant-based solutions that not only protect your home but also respect the earth

1. Soybean oil: A robust, natural insecticide

Six Feet Under Non-Toxic Insect Spray harnesses the potent insecticidal properties of soybean oil, (turning this everyday kitchen ingredient into a formidable pest control weapon). Its 3.13% concentration in our formula effectively smothers insects by:

  • Clogs their spiracles
  • Hinders their respiration
  • Leads to their asphyxiation

This mechanical action is particularly effective against a broad spectrum of six-legged insects, ensuring a rapid and efficient kill.

By disrupting insect egg metabolism and feeding mechanisms, soybean oil reduces hatching success and starves pests, all without leaving toxic residues. This ensures minimal disruption to beneficial insects and reduces the likelihood of resistance development

2. Cinnamon oil: A powerful insect deterrent 

Six Feet Under utilizes the robust insecticidal properties of cinnamon oil, a key ingredient with a long history of repelling pests. This aromatic oil, at a concentration of 0.03% in our formula, has demonstrated high efficacy against pests like:

Its potent aroma and natural compounds make it an effective, safe alternative to synthetic insecticides.


Cinnamon oil's use as an insect repellent dates back to ancient times, (particularly for grain protection). In Six Feet Under, its combination with other essential oils—like soybean and clove—creates a powerful, lab-proven blend that disrupts the exoskeletons of various pests.

This synergistic effect not only enhances the absorption of the formula but also ensures rapid and effective pest elimination. 

3. Clove oil: A versatile insect repellent

As a crucial component in Six Feet Under, clove oil, with a 0.05% concentration, serves as an all-natural, rapid-acting insect repellent. This powerful oil has traditionally been used to repel bugs, including when applied to bed sheets. In Six Feet Under, its efficacy extends to repelling and killing a wide array of pests—like mosquitoes, ants, wasps, moths and flies

What sets clove oil apart in the realm of pest control? Its effectiveness derives from eugenol:

  • Neurotransmitter interferenceEugenol in clove oil affects the neurotransmitters of pests, particularly those involved in movement and metabolism. This disruption causes a rapid knockdown effect that incapacitates insects almost immediately upon contact.
  • Strong repellent aroma: The robust aroma of clove oil is naturally unappealing to insects, making it an excellent deterrent and adding an additional layer of protection by preventing pests from approaching treated areas.

The inclusion of clove oil in Six Feet Under aligns with our commitment to non-toxic, poison-free pest control solutions. Unlike synthetic chemical insecticides, which are increasingly facing resistance from insects, clove oil remains effective. Its natural properties ensure that Six Feet Under is a safer alternative for homes, free from toxic fumes, harsh chemicals and synthetic pesticides

4. Peppermint oil: A robust natural repellent

Peppermint oil stands out as a key active ingredient in our quest for non-toxic pest control. Known for its potent ability to repel a variety of pests—including ants, aphids, beetles, cockroaches and even mosquitoes—peppermint oil is a cornerstone of our safe and effective Dust to Dust Non-Toxic Insect Powder formula. Its major chemical compounds—terpene, alcohol and menthol—act as natural fumigants, deterring pests through their strong aromas.


Studies have demonstrated the impressive biocidal properties of peppermint oil, highlighting its potential as a natural alternative to traditional chemical pesticides:

In Dust to Dust, peppermint oil's dual role as a pest repellent and a family-safe ingredient exemplifies our commitment to harnessing nature's medicine in creating non-toxic, yet powerful pest control solutions.

5. Rosemary oil: A potent, natural insecticide

In our relentless pursuit of eco-friendly pest control solutions, rosemary oil emerges as a standout ingredient in Dust to Dust. Its potent insecticidal and repellent properties are attributed to compounds like camphor, cineol and borneol.


These components effectively:

  • Interferes with the nervous systems of insects
  • Disrupts their pheromone communication
  • Creates a suffocating barrier

The efficacy of rosemary oil against a range of pests is well-documented in scientific studies. An article published by the National Library of Medicine writes of its ability to cause complete mortality in spider mites without harming the host plant, whereas a study published by Cornell University speaks of its prolonged repellent effect on mosquitoes, highlighting its versatility. Further research by Research Gate underscores its remarkable insecticidal properties, demonstrating the complete eradication of adult rice weevils. 

6. Silica: A dual benefit for plants and pest control 

Absolutely, using bullet points can make the benefits of silica clearer and more digestible for readers. Here’s how you could structure this information:

Silica: Dual benefits for plants and pest control

In Dr. Killigan's Dust to Dust, silica serves a dual purpose that benefits both garden health and pest control:

  • Bolsters plant structure: Silica plays a crucial role in strengthening the structural integrity of plants, giving them the foundational support needed to flourish.
  • Enhances resilience and vigor: By providing essential nutrients, silica helps to enhance the resilience and vigor of plants, making them more robust against environmental stressors.
  • Acts as an abrasive nature against pests: The sharp, pointed edges of silica particles act as a physical deterrent to pests. When insects encounter these abrasive particles, they suffer physical damage leading to dehydration and death.
  • Provides nourishment for plants: Beyond its pest control properties, silica also nourishes plants. This mineral is vital for the healthy growth and development of plants, contributing to overall garden vitality.



    Silican's natural approach to pest control, backed by scientific research, ensures effective management without harming the environment. 

    7. Eastern red cedar: Nature's aromatic protector

    Dr. Killigan's Cedar Planks, crafted from 100% eastern red cedar, embody more than just pest repellence. This remarkable wood, with its natural properties, effectively wards off moths and other fabric pests, safeguarding your clothing and linens. Its inherent ability to repel bugs is just the beginning; cedar represents nature's ingenuity in providing solutions to modern challenges.

    Beyond its functionality, eastern red cedar infuses your home with a subtle, earthy aroma, akin to natural aromatherapy.


    This scent transforms your closets into havens of peace. Dr. Killigan's Cedar Planks not only offer pest protection but also enhance your living space with the timeless wisdom of nature. 

    8. Vinegar: The power of organic acidity

    In Sweet Surrender Fruit Fly Trap Refill Liquid, the inclusion of red wine vinegar plays a crucial role in pest control. Sourced from select California grapes, it undergoes a specialized fermentation process, heightening its effectiveness against fruit flies. This vinegar:

    • Targets the specific sensory preferences of these pests (with its aroma reminiscent of overripe fruits)
    • Lures fruit flies into the traps with the allure of fermenting fruits 
    • Disrupts their reproductive cycles

    By leveraging the natural allure of red wine vinegar, we offer a potent, sustainable solution to manage fruit flies, ensuring the safety and well-being of families and the environment. 

    9. Citric acid: Harnessing citrus power for fruit fly attraction

    Citric acid, originally sourced from lemon juice, is a key element in Sweet Surrender's effectiveness against fruit flies. This organic compound, particularly potent due to its terpene content—like limonene—is naturally appealing to fruit flies, as it mimics the enticing scent of citrus fruits – their preferred choice. The citric acid's combination of natural acidity and citrus aroma provides a powerful lure that fruit flies find irresistible.

    nature's medicine

    Citric acid's role extends beyond attracting pests; it also serves as a natural preservative, giving Sweet Surrender a shelf-life of two years when stored correctly. 

    10. Sucrose: The sweet lure for fruit flies

    Sucrose, a natural sugar, is a crucial component in Sweet Surrender. Its effectiveness in luring fruit flies stems from their innate need for sugar as a quick energy source for their constant flying. This natural lure satisfies their sugar cravings, making sucrose an efficient attractant in our traps.

    Incorporating sucrose into Sweet Surrender is in line with our philosophy of utilizing nature's medicine for pest control. This non-toxic and safe sugar ensures that our traps are not only highly effective but also pose no harm to humans or pets.
