The role of stearic acid in pest control


Today, we’re delving into a not-so-talked-about hero in the realm of non-toxic pest control—stearic acid. You might be familiar with stearic acid as a component in various products, but did you know it plays a crucial role in disrupting the life cycles of pests, offering a safer alternative to traditional chemical pesticides

Let’s uncover how this simple yet effective ingredient is making strides in our continuous battle against pests.

Understanding stearic acid

Stearic acid is a versatile saturated fatty acid that's widely used across various industries due to its beneficial properties. Found naturally in animal and plant fats, stearic acid is most commonly sourced from palm oil, cocoa butter and animal tallow. It appears as a waxy solid at room temperature and is often used in the production of soaps, cosmetics and detergents due to its ability to harden and thicken products. 

Benefits of stearic acid in environmental safety

Stearic acid is a key component in Dr. Killigan’s Dust to Dust Plant-Powered Insect Powder, chosen for its compatibility with our environmental and safety values. 

Here’s how stearic acid contributes to making our products a safer choice for both users and the environment:

  • Non-toxic formulation: By using stearic acid, which is derived from palm sources, we ensure that our products are non-toxic. This makes them safe to use around your family and pets.

  • Protection of active ingredients: Stearic acid creates a protective matrix around the essential oils and other active ingredients in our products. This barrier:
    • Prevents premature degradation: Ensures that the active ingredients remain effective longer, resisting breakdown from environmental factors such as light and air exposure.
    • Enhances efficacy: Improves the contact of active ingredients with insects, ensuring that the pest control agents are more effective at targeting and eliminating pests.

  • Enhanced user experience: The matrix formed by stearic acid also prevents clumping and ensures easy application. Users benefit from a product that spreads evenly and effectively, without the hassle of dealing with lumps or uneven distribution.

  • Regulatory compliance and safety: At Dr. Killigan's, we focus on the safety and compliance of our pest control solutions with stringent standards. Our use of stearic acid and other natural ingredients aligns with the U.S. Environmental Protection Agency’s (EPA) guidelines for "minimum risk pesticides." These substances are recognized by the EPA as posing little to no risk to human health or the environment, exempt from federal registration but rigorously assessed for safety. 

          These benefits showcase how stearic acid not only supports the effectiveness of our pest control solutions but also aligns with our core values of safety and sustainability. 

          Case study | Proven effectiveness against pests


          Recent research underscores the effectiveness of stearic acid in combating troublesome pests, such as the sugarcane aphid. This pest has historically caused significant issues, and studies show that stearic acid can serve as a potent component in pest control strategies. By incorporating stearic acid into Dust to Dust, Dr. Killigan’s ensures that you are using solutions backed by research for their efficacy against common pests.


          The role of stearic acid in pest control illustrates how traditional ingredients continue to be fundamental in solving modern problems. At Dr. Killigan's, we are proud to incorporate such elements into our products, ensuring they are safe, effective and environmentally friendly. Our commitment to sustainability and effectiveness is reflected in every bottle, backed by the power of nature and science.
