By Dr. Killigan

Welcome to Dr. Killigan's realm, where nature's medicine is the cornerstone of our pest control philosophy. Our commitment to harnessing the healing powers of the Earth guides our selection of 12 vital plant-based ingredients. These natural wonders are not only effective in battling pests but also embody our pledge to eco-conscious living. Join me on a journey through nature's medicine cabinet, as we explore each ingredient's unique role in our non-toxic pest control products. 

1. Soybean oil in Six Feet Under: A robust, natural insecticide

Mechanical action of soybean oil: 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 clogging their spiracles, hindering respiration and leading to asphyxiation. This mechanical action is particularly effective against a broad spectrum of six-legged insects, ensuring a rapid and efficient kill.

Eco-friendly and sustainable pest control: Our use of soybean oil in Six Feet Under exemplifies Dr. Killigan's dedication to eco-friendly and sustainable pest management. By disrupting insect egg metabolism and feeding mechanisms, it 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. Our approach with soybean oil not only guarantees high efficacy against household pests but also embodies our commitment to utilizing nature's resources responsibly and sustainably.

2. Cinnamon oil in Six Feet Under: A powerful insect deterrent 

Insecticidal efficacy of cinnamon oil: Six Feet Under harnesses the robust insecticidal properties of cinnamon oil, a key ingredient with a long history of repelling pests.

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


Historical and modern usage: 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, including ants, cockroaches and moths. This synergistic effect not only enhances the absorption of the formula but also ensures rapid and effective pest elimination, adhering to our commitment at Dr. Killigan's to provide eco-friendly and non-toxic solutions for pest control.

3. Clove oil in Six Feet Under: A versatile insect repellent

Clove oil's multifaceted insect repellent properties: 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, such as mosquitoes, ants, wasps, moths and flies. This makes clove oil an essential ingredient in our formula, offering a safe and effective means to keep bugs at bay.

Natural and resistant to insecticide immunity: 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. This not only makes it an environmentally friendly choice but also a future-proof solution in the ongoing battle against pest resistance.

4. Peppermint oil in Dust to Dust: A robust natural repellent

Peppermint oil's comprehensive pest repelling abilities: Peppermint oil stands out as a key active ingredient in our quest for non-toxic pest control.

Its major chemical compounds—terpene, alcohol and menthol—act as natural fumigants, deterring pests through their strong aromas.

According to a study by the National Library of Medicine, peppermint oil demonstrates a high efficacy against various pests, including a 97.2% mortality rate in brown-banded cockroach nymphs. Furthermore, in an additional National Library of Medicine study, its comparison to DEET in repelling mosquitoes underscores its potential as a safe and natural protective measure. 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 in Dust to Dust: A potent, natural insecticide

Recognized for its non-toxic, biodegradable nature, rosemary oil is a compelling alternative to chemical insecticides.

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.
