Why this exists

“While my son was receiving cancer treatment at MD Anderson, a maintenance technician came in to spray for insects. I read the label. It was petroleum-based and contained known carcinogens — chemicals that would linger in the very air my son was breathing.

That moment became a turning point.”

— Dr. Robert “Bob” Flournoy

He set out to build a safer alternative. It took years of research, formulation, and testing.

The problem

What we have been spraying in our homes

For decades, households relied on conventional bug sprays, trusting they were safe and effective. Today we know many traditional pest control products contain harmful toxins, and some contain carcinogens. The EPA has restricted certain ingredients, but many chemical-based sprays remain on shelves.

Today we’re exposed to environmental toxins in the air we breathe, the water we drink, and the products we carry into our homes. Dr. Bob’s offers a smarter approach — protecting your space without adding unnecessary chemicals.

The inventor

Meet Dr. Robert “Bob” Flournoy

Dr. Bob was born in Tulsa and has spent most of his life in north Louisiana. He is a professor, a research scientist and an entrepreneur — a man who has always been more interested in what a thing is made of than in what its label claims.

He taught bioscience, anatomy, physiology and endocrinology for a decade at Louisiana Tech, did postdoctoral work with NASA, and later founded an environmental laboratory that tested water, air and hazardous waste for cities and businesses across the region.

The throughline is simple: he has spent his whole life on the science of what’s in our environment. Dr. Bob’s Natural Bug Defense is that career, distilled into a bottle you can keep under the kitchen sink.
