STEM harnesses nature's bug-fighting power and engineers it safely* into your hands.
Most bug problems are solved using conventional chemicals and pesticides. Or not solved at all by ineffective formulas. STEM is different. Our formulas are powered by plant-derived active ingredients, scientifically engineered into effective bug-fighting formulas. So you can fight bugs safely* and effectively.
Safe for use around
people + pets*
No added dye,
fragrance or harsh
SAFE* FOR PEOPLE & PETS
STEM is harsh on bugs, but safe* around humans. Our formulas are extensively tested for effectiveness and safety, and powered by plant-derived active ingredients, so your curious kids (and fur-babies) don’t need to evacuate the room when you’re treating a bug problem.

Effective plant-derived active ingredients that work even better as a precise formula.
Our insecticides are thoughtfully designed for specific bugs with specific formulas. And our bottles and sprayers are selected to target specific bugs types.SEE ALL BUG KILLERS
Our bug repellents are made with plant-derived active ingredients and, like our insecticides, have been extensively tested for effectiveness and safety (when used as directed).SEE ALL REPELLENTS
