Most mosquito repellent devices rely on airborne fumes to either kill mosquitoes or drive them away, or electric circuitry to zap mosquitoes out of existence… so you’re either left with a room that smells of repellent, or a device with dead mosquitoes gathering in the collection pan. Effective, yes. Elegant? No.
Baseus’s Mosquito Killer does a much better job without zapping or fumigating. Lure the critters in with a UV lamp set at a wavelength that attracts them, and suck the mosquitos in using a powerful 7-blade vortex. The result is an elegant looking device that feels more domestic than industrial, fitting well in most homes… not just because of its home-friendly contemporary design, but also because it’s a whole lot safer (especially around babies) than those poisonous repellents.
