VI. Bird Control General Considerations
A. It’s the scent
Bird control with the Avian Plus system is simple. The magic is in the Avian Plus fragrances which have
been designed to be pleasant only for humans.
B. Installation Objective
The objective of any Avian Plus bird control installation is also simple – deliver the scent to those places
where birds are likely to congregate.
C. How many machines?
The number of machines and the amount of scent (concentration) needed to clear the birds will depend on
two main variables.
1. Size of the space in cubic feet. That’s the entire enclosed space not just the area frequented by birds.
Step it off length x width gives you square feet x ceiling height for cubic feet.
2. Quantity of fresh air flow in the space because fresh air dilutes the scent concentration in the air. This
is an important variable but often very difficult to estimate accurately.
The rule of thumb is that one (1) Air/Q 1100-Avian will service UP TO 150,000 cubic feet. So you will need
at least one appliance for every 150,000 cubic feet. If the air flows are unusually strong with a lot of fresh
air, you may need more machines.
D. Positioning of the appliances for wall mounting must consider the following:
1. Direction of air currents in the space. It is important to not fight the natural air currents in a space.
The rule: always position the appliance(s) upwind so the natural flow of air helps to move the scent to
where the birds are.
2. Determining air flow takes a little time. Usually spaces, even quite large ones, have a natural flow of
air either into or out of the portals or openings. A space with “positive pressure” pushes the air to
the outside. A space with “negative pressure” pulls the air in. Make a rough map of the space on a
piece of paper. Stand near the door, light a candle and then snuff it out and watch the direction of the
smoke. Do this all over again in different locations drawing arrows to indicate the direction of air flow
until you can confirm a general directions. Keeping in mind where the birds are, this map will tell you
where to position the wall mounted appliances for optimal flow of scent to the birds.
3. Ceiling fans can help or hurt. If the birds are above ceiling fans pushing the air down, then there are
only 2 choices:
a) Reverse the fan direction so they are pulling the air up; or
b) Use the optional Diffusion Director so the output end is above the fans. (See p. 12)
