Ultrasound consists of high-frequency sound waves which are
perceived by the mosquitos, flies, mice and cockroaches, but
cannot be heard by humans.
The ultrasound waves fan out uni-directionally from the
PEST
COMPLETE REPELLER HOME like fluorescent light. Hard substances
(walls, ceilings, furniture, glass, etc.) promote better spreading out
of the sound waves, as they bounce off these surfaces, whereas
soft materials (cardboard, curtains, carpeting, etc.) absorb the
sound waves.
When installing the
PEST
COMPLETE REPELLER HOME, take
into account that the ultrasound waves do not penetrate walls
(brick, plaster, etc.), or wooden room dividers, glass, plasterboard
false ceilings or other solid materials. Hang the
PEST
COMPLETE
REPELLER HOME inside the area you wish to protect. Avoid
Human
Mosquitos
Flies
Cockroaches
Rodents
