Aversion Technologies is the world’s premier source of aversive masterbatches and chemicals. We offer both naturally occurring compounds and synthetic chemicals to companies around the world, making their products safer and less likely to be damaged by animals.

Our masterbatches and specialty chemicals render products unpalatable to animals and humans. They prevent insects from attaching plants and invading homes. They protect children and pets by preventing them from consuming dangerous goods liquids and pastes. Exposure to aversives chemicals results in future avoidance - behavior modification that leads to long-term protection of people, pets and plants.

Our Repela™ masterbatches are primarily incorporated into plastic materials, such as electric and fiber optic cables, plastic pipes, and agricultural mulch. The active ingredients in Repela are incorporated into ethylene vinyl acetate (EVA). This makes Repela a compatible with a wide range of polymers. Typical letdown rates are 3-5% for Repela™ for Rodents, Repela™ for Insects, and Repela™ Combi.

Chief among our chemical aversives are products are the synthetic bitterants denatonium benzoate and denatonium saccharide; the naturally hot and spicy capsaicin derived from hot peppers, nonivamide, a synthetic analogue of capsaicin, and the naturally occurring bitterants colocynth and andrographolide.

Protect people and pets by changing their behavior and without causing any harm? What a great idea!

Living on planet Earth with millions of other species creates all sorts of frictions. We want our pets protected; we want our crops protected; we want our loved ones and ourselves protected. But protection can often mean harm. Sometimes it means vigilance, or inconvenience, or inaccessibility. But we think the best way to achieve protection is through behavior modification. Make dangerous liquids unattractive to children and pets, make pests choose to not eat ornamental plants, make rodents choose to not chew on wires.

This concept of harmless protection became the philosophy, the animating idea, behind Aversion Technologies. Founded in 2005, we are the only company in the world that exclusively offers products to modify behavior, thereby providing protection through avoidance. We believe that behavioral change can be accomplished through conditioning in the form of distasteful - but harmless - consequences. We have found that it rarely takes more that one or two encounters with our products to cause an avoidance reaction in the future. We aspire to provide protection for people, pets and plants through the addition of these harmless substances to potentially dangerous products.
