We believe nature knows how to fight bugs and can be used to protect us.


Rooted in Nature

At STEM, we believe that humans would be better off letting Mother Nature teach us a thing or two, because if we look closely, we’re clued into the subtle ways she equips the world with natural defenses. Like the citronella plant, filled with ant-repelling geraniol or the marvel of the plant world, the Venus flytrap.

Optimized by Science

We worked with a team of entomologists to decode nature’s most ingenious defenses and optimize each of our bug-fighting formulas.

Product of the Year 2022 and 2024

Don’t just take our word for it! STEM’s bug killers and mosquito repellents formulated with botanical extracts were recognized in 2022 by ‘Product of the Year’– the world’s largest consumer-voted award for product innovation.

In 2024, STEM was recognized again! This time, for the STEM Flying Insect Light Trap device.
