WHY MOSLOCK

MOSLOCK ultrasonic design principles

Which frequencies, at what sound pressure, and in which space? These are the three foundations of MOSLOCK's design.

EVERYDAY SCENES

In bedrooms, cars
and campsites.

Ultrasound travels directionally and reflects off surfaces. Placement, distance and reflective surfaces affect outcomes, so each space requires a different arrangement.

FAQ

Start with
your questions.

Do mosquitoes really have ears? Can they hear sound?

Yes. Mosquito hearing is mediated by Johnston's organ, which serves a role comparable to our ears. It sits at the base of the antennae and contains densely packed hearing-related nerve cells.

How does MOSLOCK work?

MOSLOCK delivers sound into a space using high-output ultrasound, continuously varying Multi Sweep frequencies, five high-output ultrasonic speakers and a 360° rotating head.

Where should I put it?

In a bedroom, place it near the head or feet and keep the front clear. Outcomes may vary with the size and layout of the space.

Are the results the same in every environment?

No. The results were measured under specific test conditions. Actual outcomes may vary with mosquito species, number of mosquitoes, space size, ventilation and other factors.

Can MOSLOCK's ultrasound kill mosquitoes?

No. MOSLOCK does not kill mosquitoes; it is a repellent device designed to reduce their approach. Research has also reported reduced approach behavior in mosquitoes seeking a blood meal under ultrasound exposure.

About MOSLOCK

Launched in April 2026 as a Kia KIA Collection product, MOSLOCK is a non-chemical ultrasonic mosquito repellent co-developed by MARKT Co., Ltd. and the Research Institute of Vector-Borne Diseases at Incheon National University. Its five high-output ultrasonic speakers, Multi Sweep variable-frequency technology and 360° rotating head are designed to deliver ultrasound at frequencies and sound pressures intended for mosquito repellency.
