Product Description

MORRIS Si product background:
It is known in the art of pests control that such pests as rats, cockroaches and insects, e.g., mosquitoes, spiders, fleas and flies are very sensitive to ultrasonic vibrations. Such ultrasonic vibration of sufficient intensity and duration can affect the nervous system of these pests and eventually cause disabling or mortal effects. As a consequence, when exposed to such ultrasonic vibration, these pests either attempt to avoid it or suffer the other consequences.It is also well established through Entomological research in many countries that pests are responsive to particular ultrasonic frequencies and may be repelled by these ultrasounds in a variety of situations.As shown in figure 1, mosquitoes, black flies and mites are repelled at frequencies ranging from about 30 kilohertz to 48 kilohertz and whereas house flies, rats, beetles and moths are repelled at frequencies ranging from about 20 kilohertz to 37 kilohertz. For further available laboratory test findings.

Please refer consults the research book:
(1) H.C. Fringe "The physical Effects on High Intensity Air Borne Ultrasonic Waves on animals and Insects".
(2) E. Kent "An Ultrasonic UCS" Physiological Behavior.
(3) R.G. Bushel "Some Examples of Ultrasonic Frequency Sensitive and Frequency Insensitive Biological Reactions".
(4) K.D. Roeder "Moths and Ultrasound".

The MORRIS product is a solid unit. It should not abuse. Is the
careful whereabouts it also does not let. It with the water, or the
use relates outside it. The absorption common sound material and will
absorb the supersonic wave. The hard surface will reflect the sound
wave. Using the wave reflection character, lets the supersonic wave
get up by the MORRIS product launch sound wave along the room wall is
the lily is filled until the room the supersonic wave. Remembers,
maintenance all gates and the window are closed manages for the MORRIS
product the room to cover covers the sound wave to satisfy up to.
