STEM is a new lineup of bug killer sprays and mosquito repellents that is powered by botanical extracts formulated in scientifically precise combinations to optimize effectiveness. The entomologist-tested and scientifically engineered one-stop pest control shop is designed to be effective in killing or repelling bugs, but safe to use around humans and pets, when used as directed. The plant-derived active ingredients like lemongrass, mint and rosemary oils help fight nature with nature.

From ants and roaches to yellow jackets and fruit flies, the STEM Bug Killer line conveniently showcases the bugs it is designed to kill within the name, making it easier for families to select the right product for their needs. The full line includes sprays for ants, roaches, flies, spkers, flies, mosquitos, gnats, wasps, hornets and yello jackets as well as a fruit fly trap. Additionally, the STEM Mosquito Repellent line includes two convenient options for protecting families during the peak season, including STEM bug repellent spray  and bug repellent wipes for mosquitos. The wipes use  plant-derived active ingredients and is safe for use on kids (6 months and older, when used as directed) to keep mosquitoes away. 


“We have been hard at work developing STEM for the last few years with the knowledge that certain botanical extracts contain chemicals that naturally immobilize bugs,” explainsan Entomologist at the SC Johnson Center for Insect Science and Family Health. “So, we used these extracts in scientifically precise combinations to optimize effectiveness on bugs, while ensuring they are safe to use around humans and pets, when used as directed. We then conducted rigorous testing to ensure the plant-powered products deliver the efficacy we know our customers expect.”


STEM insecticides and repellents have no added dye, fragrance or harsh chemical odor. The plant-derived active ingredients like lemongrass, mint and rosemary oils provide an effective solution, while the nozzles are specifically designed to target.

STEM was already named an official Product of the Year in 2022 for outstanding innovation through a national survey of 40,000 American shoppers conducted by Kantar, a global leader in consumer research. With a distinctive red seal that is globally recognized as the vote of confidence from consumers themselves, shoppers can easily cut through the clutter and trust that STEM demonstrated the utmost innovation in the pest control category for function, design, packaging and ingredients. 

“Given the continued flux and uncertainty over the past two years, we’re prouder than ever to provide consumers with the vote of 40,000 fellow shoppers as a guide they can trust when making important purchase decisions for themselves and their families,” said Mike Nolan, Global CEO of Product of the Year Management. “One of the great strengths of Product of the Year is that we champion products like STEM that use the latest industry innovations and insights to offer consumers much-needed solutions for common household needs like pest control.”
