Your Flowrtron Mosquito PowerTrap emits a plume of
octenol-enhanced carbon dioxide which mosquitoes
follow in their search for a blood meal. Mosquitoes fly
up-wind toward the source of the plume in their at-
tempt to locate a host. Since the direction of the
plume is dependent upon the direction of the wind,
your unit should be positioned so it’s

4. This device was designed for use
with propane gas. Never attempt to
use any other fuel, including liquid
fuels or natural gas. Fire or damage
to your Flowtron PowerTrap could
result.
Check for gas leaks by wetting the connec-
tions with a solution of soap and water and
watching for bubbles. If bubbles form or if a
bubble grows larger, there is a leak and
connection must be tightened.

2. Insert one end of the
post into the post opening at the front of the tank
stand. Insert opposite end of post into the post
opening located at the bottom of the Flowtron
Mosquito PowerTrap®. Align unit in relation to the
tank stand. See Illustration 2.
For best results locate your unit 20 to 40 feet away
from areas of human activity in a location near (but
not in) bushes, wooded areas, or adjacent to standing
water (other than swimming pools). Select a location
which will result in the carbon dioxide plume blowing
toward the area where mosquitoes are likely to hide
and emerge. A proper location will ensure that
mosquitoes encounter the plume and follow it up-
wind to the Flowtron Mosquito PowerTrap before
they detect the presence of humans.
WARNING
Place a 20 lb. tank on the tank stand and install
tank wrap around the tank.
Check for gas leaks every time you disconnect and
reconnect a gas fitting.

When a timed mode is selected, the fan and LED
lights will come on immediately and remain on. The
unit, however, waits for dusk and then checks the out-
side air temperature to determine if it is sufficiently
warm for insect activity (above 55º – 60ºF). This is an
important feature to conserve propane fuel. The unit
will automatically begin its start cycle when the light
level reaches dusk and remains at the level of dusk
for ten minutes (thus avoiding the effects of transient
light sources) and if the outside air temperature is
above the 55º – 60ºF range.
Operation
Your Mosquito PowerTrap is fully automatic. It is
equipped with a photocell, temperature sensors and a
computer microprocessor.
Your Enemy – the Mosquito
There are some 2,700 species (different kinds of
mosquitoes) in the world with about 170 species in
North America alone.
How Your Flowtron
Mosquito PowerTrap Works
The revolutionary new Flowtron Mosquito PowerTrap
replicates the attractants mosquitoes use to locate, bite
and annoy humans. It does this by producing carbon
dioxide, heat and moisture and combining these stimuli
with octenol to create an attractant to mosquitoes.
The control panel is located on the top of the unit and
has the following operating modes:
Most mosquitoes live and die close to where they
hatch, although some can travel miles in search of a
host. Only the female mosquito bites as she requires
a blood meal to produce eggs.
•
•
•
24/7 (on 24 hours, 7
days/week)
Your Flowtron Mosquito PowerTrap:
•
Replicates the human attractants of respiration,
odor, body heat.
Mosquitoes require standing water in aquatic habitats
including fresh water, salt water marshes, brackish
water or in water found in containers, old tires, tree
holes, even flower pots. The female mosquito lays
her eggs on the surface of the water and if conditions
are right the eggs hatch and become larvae, then pu-
pae and finally adult mosquitoes; all in 10 to 14 days.
3 Hours (on at dusk,
off 3 hours later)
The start cycle is also repeated at dawn when the 3 +
2 hr or the 4 + 3 hr mode is selected.
•
Converts readily available propane gas into heat,
moisture and carbon dioxide, the acknowledged
leading mosquito and attractants emitted by hu-
mans.
3 + 2 Hours (on at dusk,
off 3 hours later; on again at dawn, off 2 hours lat-
er).
During start cycles, which are from five to ten
minutes in duration, the fan and LED lights operate
intermittently.
•
•
4 + 3 Hours (on at dusk, off 4 hours later;
on again at dawn, off 3 hours later)
•
•
Produces a powerful vacuum to draw mosquitoes
into a convenient, removable catch tray where
they quickly dehydrate and die for safe, clean dis-
posal.
Both male and female mosquitoes feed regularly on
nectar obtained from flowers, but females require
blood to produce fertile eggs. Therefore, she must
find a human or animal host to blood feed before she
can lay her eggs.
Off/Reset (manual off)
Ten to fifteen minutes after the unit detects a lack of
propane fuel (either due to an empty tank or due to
improper installation of the propane regulator to the
tank valve) the three green timed mode lights on the
control panel will flash. Simply switch the PowerTrap
off and refuel. If the unit is not out of propane and the
lights are flashing check that the tank valve is fully
open and that the regulator is properly attached to the
tank valve.
To select the desired mode, first push the button la-
beled “Off/Reset” to clear the computer memory.
Then push the button labeled “Mode”.
Contains state-of-the-art computer controlled elec-
tronics to operate automatically in one of four
modes selected by you.
Most mosquitoes that emerge in the wild never come
in contact with humans but obtain blood from birds
and other animals. Mosquito species that breed
around the home remain close to where they hatched
and are regarded as pests and carriers of disease.
For continuous operation press the “Mode” button
once. The green light labeled “24/7” will light and the
unit will operate continuously 24 hours per day until
the “Off/Reset” button is pressed.
Mosquito PowerTrap does away with ultraviolet lights
and high voltage killing grids. Most importantly, it kills
only female mosquitoe.
For timed operation, press and hold the “Mode” but-
ton. When the desired mode is selected as indicated
by its green light, release the button. No further con-
trol is necessary and your unit will function in the
mode selected every day until the “Off/Reset” button
is depressed or an interruption occurs in the electrical
power source.
Mosquitoes and biting flies are generally most active
shortly after dusk and again at dawn. Therefore, the 3
+ 2, or 4 + 3 timed modes are usually the most eco-
nomical settings.
Flowtron Mosquito PowerTrap uses an exclusive plat-
inum catalyst that converts air and propane gas into
heat, moisture and carbon dioxide. It does this in an
efficient, effective and economical manner. The cata-
lyst converter is completely safe, flameless and never
needs to be replaced.
Mosquitoes in search of a blood meal use visual,
thermal and olfactory (odor) stimuli to locate a host.
Of these, olfactory cues are the most important.
Out of the more than 100 compounds detected in hu-
man breath only two have been isolated and identi-
fied as significant mosquito and biting fly attractants;
carbon dioxide (CO2) and octenol (1-OCTEN-3-
OL). These attractants serve as long-range airborne
attractants and can be detected by mosquitoes and
biting flies at distances of 100 feet to 125 feet.
The 24/7 mode is desirable if day flying mosquitoes
are present or to operate at temperatures below 55º
F.
Note:
To resume operation following an electri-
cal disturbance or a loss of electrical
power, press the “Off/Reset” button to
clear the computer memory then reset
the unit to the desired operating mode.
At close range, body heat, moisture and lactic acid
serve as terminal attractants. Certain species show
strong preferences for biting different parts of the hu-
man body. This is thought to be related to local skin
temperature and lactic acid output.
In the event the PowerTrap fails to respond
to its controls (mode selection) unplug the
unit for a few seconds, reattach plug and
then reset to the desired mode.
Note:
As mosquitoes and biting flies pass through
the fan, most are killed and thrown against
the side of the internal screen-lined funnel.
Those that escape the fan’s killing action
end up in the catch tray where they quickly
dehydrate and die. See page 7 for instruc-
tions for removing the screen-lined funnel
and cleaning the screen.
The attractiveness of different persons to mosquitoes
varies substantially. Men are bitten more readily than
women, adults more often than children and larger
persons attract more mosquitoes perhaps because of
their greater relative heat and carbon dioxide output.
When the 24/7 mode is selected, the unit will begin
its start cycle and approximately three minutes later,
the fan and LED lights located in the entrance to the
trap will come on intermittently. Once the catalyst
has reached operating temperature, which will take
five to ten minutes, the fan and LED lights will remain
on and the start cycle will be complete.
