Backyard AVENGER™ - Theory of Operation
The patented Backyard AVENGER™ utilizes a number of design
features to attract and subsequently kill target insects. Heat,
moisture, chemical attractant, color, rhythmic release of the
chemical cues are all incorporated into the unit. Chemical attractants
can be changed to target specific insect types.
The Backyard AVENGER™ uses computer designed power electronics
to control the temperature and the rhythmic release of the chemical
cues. The chemical attractants can be varied depending on the
target insect to be controlled.
Insects will detect the chemical cues from great distances and
be drawn to the source. Those using chemical cues will find the
“source” behind the killing zone. Naturally, they
will fly to the “source” through the killing grid
and fall into the insect container. Garbage Flies (house flies)
and yellow jackets are common pests which can be targeted using
commercially available attractants or even food stuffs commonly
available in the home.
Since the Backyard AVENGER™ has precision thermal control
and the ability to use and disperse carbon dioxide (CO2), the
unit is irresistable to blood seeking insects like female mosquitoes.
Not only does the unit mimic the thermal patterns created by warm
blooded mammals, but its rythmic release of CO2 and other attractants
mimics the breathing of warm blooded mammals. Research has shown
that periodic release of CO2 produces much a better attraction
to female mosquitoes than does a steady release of CO2 like that
is produced by mosquito traps that burn propane to create the
The rate at which the CO2 flows into the unit is determined by
a user adjustable needle valve located at the top of the unit.
It is set at the factory for a release rate of 500 ml/min but
could be increased up to>4,000 ml/min (flow rate limited by
the pressure and restrictions of the gas flow path between the
CO2 tank and internal solenoid valve). Arguably, increasing the
amount of CO2 will increase the coverage area of the unit.
