Most electronic mosquito repeller (EMR) applications are developed from the misunderstanding that mosquito repellent may be similar to electronic pest repellent which emits inaudible high frequency sound for rats and mice. But it is simply wrong.
EMR is based on the theory that female mosquitoes tend to avoid male mosquitoes when they feed on human blood to develop eggs. Mosquitoes generate sound by wings while flying. Thus EMR should generate wing frequency of male mosquitoes.
The frequency of male mosquito is audible and not really very high.
The difficulty of the sound simulation lies in the difference of frequency according to the species and location of mosquitoes.

Mosquito Zapper generates intermixture of several wing frequencies of male mosquitoes to repel female mosquitoes for 3 different types of location.
Mosquito Zapper is the most advanced EMR application that is made by the result of co-work with ethnoentomologist in order to simulate frequency of male mosquitoes more precisely.

HOW TO USE
Choose one of three types of location. You don’t have to make the volume too loud. (Make it loud when you use earphones instead of speaker).

FEATURES (3-in-1)
- When you are in urban area.
- When you are near the seaside or lakeside.
- When you are in a mountainous or farming district

THEORY
Female mosquitoes bite human because they need supplemental substances such as protein and iron to develop eggs.
The frequency of male mosquito is not really very high and it differs by the species and location of mosquitoes.
EMR should generates intermixture of several flying (wing) frequencies of male mosquitoes to repel female mosquitoes.
Effectiveness of the sound of Mosquito Zapper is verified by demonstrations and resulted from the co-work with ethnoentomologist.
Female mosquitoes are sensitive to carbon dioxide, humidity, and vivid colors.
