The Science Behind the World's Only Repellent Patch
Any brand can claim its product is "natural".
Any brand can promise that it "works."
Not every brand can say this: Our repellent patch was tested by TECNALIA — the largest private technology center in Spain — and demonstrated real efficacy against Anopheles Gambiae, the mosquito that transmits malaria. That is the SAHHA standard. No promises. Independent science.

TECNALIA is no ordinary lab. With over 1,400 researchers and a presence in more than 45 countries, it is the largest private center for applied research in Spain. When TECNALIA signs an efficacy report, it is because the results support it. No nuances. No exceptions.
It is the deadliest mosquito on the planet — the main vector of malaria, responsible for more than 600,000 deaths per year according to the WHO. Validating against this species is the highest possible level of demand for a natural repellent.
