The First New Bug Spray in 25 Years: How Michelle Arnau Built Mimikai
We’re creating space for the brains behind the brands we love, and asking good questions along the way. The result is a deep dive into the how and why of brand-building, from blueprints to launch day, customers as community and the detours in between. Big lessons, easy listening.
the Show Notes
In this episode of Read Receipt, Sean sits down with Michelle Arnau, co-founder and co-CEO of Mimikai, the first plant-based insect repellent proven to match DEET and picaridin without the toxic chemistry.
Michelle traces an unlikely path to founder. She started in banking, turning around troubled real estate for Wells Fargo, then went to Kellogg for her MBA and spent twelve years at Method, helping scale it from an unprofitable startup to an SC Johnson acquisition. After Method she co-founded the clean pet care brand Rowan before winding it down.
Mimikai found her next. A college friend connected her to Stephanie Watson, who had spent years fighting the EPA to register undecanone, a compound derived from wild tomato plants and the first new repellent active in twenty-five years. Michelle got on a plane to Australia the following week and came on as co-founder to lead the U.S. launch.
It is a story about knowing a category cold, saying no to the wrong retailer, and building slow on purpose so the brand can last. From launching in Credo and REI to a Good Morning America moment that drove thousands of orders in a day, Michelle makes the case for patience as a strategy.

Takeaways
- Regulatory clearance is a moat. Undecanone took years and real capital to push through the EPA, but it made Mimikai the first new repellent active in 25 years, and that is something competitors cannot simply copy.
- Know the category before you enter it. Michelle had already worked on a natural repellent earlier in her career that failed because the chemistry was not there, so she understood undecanone's value instantly.
- Sequence distribution on purpose. Mimikai launched in two branded homes, Credo for clean beauty and REI for the outdoors buyer, before chasing mass shelf space, and led with velocity and repeat over door count.
- Saying no is a strategy. Michelle turned down a large retailer because the brand was not ready to support it well, backed by investors who wanted the long game over short-term revenue.
- Complementary co-founders travel far. Stephanie Watson owns product and innovation from Australia, Michelle owns the U.S. launch, brand, and go-to-market. Same values, different skills, different hemispheres.
Sound Bites
- "When people hear that there's finally an insect repellent that works just as well as DEET but is natural, non-toxic, and safe to put on my kids and my dog, it's an unlock. I don't have to convince them of anything."
- "She was fighting the EPA for five years to get this through, and what she got through was the first new active in 25 years."
- "You've got DEET from the 1940s, picaridin from the 1980s, and now you have undecanone. Same hours of repellency, but it's natural."
- "It's not about the short-term revenue gain. It's about the long-term category disruption and doing it right."
- "I hope that my niece's children never use DEET. If that's the legacy I can leave, that we finally changed a category my dad used as a kid, that's pretty cool."
- "We were on Good Morning America and had over three thousand orders in one day. It just told us how much need there is for this."
- "Mimikai comes from biomimicry, and the Kai part comes from the island of Boracay. But my dog's name is Kai too."
