Could a simple device keep mosquitoes away better than spraying?
NCT ID NCT07387341
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests new devices called LASER that release a chemical to repel mosquitoes, comparing them to indoor insecticide spraying and standard prevention (bed nets, vaccines). About 22,800 people in 69 Kenyan villages will take part over two years. Researchers will check malaria rates in children aged 1-15 every six months to see if the devices work as well as or better than current methods.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transfluthrin (a chemical that repels and kills mosquitoes)
- What this could lead to
- If successful, LASER devices could offer a new, easy-to-use tool to protect communities from malaria, especially in areas where current methods are not enough.
- What could go wrong
- This is a large trial, but the devices are new and may not work as well as indoor spraying. The study is in one region, so results may not apply everywhere. Also, mosquitoes could become resistant to the chemical over time.
