Remember, when installing the MICE | COCKROACHES
REPELLER HOME, that ultrasound waves do not penetrate
walls (brick, plaster, etc.), or wooden room dividers, glass,
plasterboard false ceilings or other solid materials. Hang the
MICE | COCKROACHES REPELLER HOME inside the space to
be protected, and avoid blocking the flow of the ultrasound
waves from the front part of the device.
The graph shows how ultrasound waves bounce back and
spread, creating a protective shield.
