This means
removing all the nests
present in the area to be protected.
This is a fundamental step because resident birds, such as pigeons, will
never abandon the place where they live. Also, when possible,
eliminate
any source of food . Creating discomfort by breaking the habit of the
birds to be eliminated will make the use of the repeller much more
effective over time. The device should always be installed as close
as possible to the place where the largest number of birds are found
feeding or roosting. It is very important to try to scare as many birds
from the very beginning.
Before proceeding with the installation, find out about
applicable council regulations in order to use the device in line
with the urban setting.
Difference between electronic and natural sounds
of the BS-15 chip
It is practically impossible to eliminate 100% of birds.
Electronic
control of birds is aimed at deterring the majority of them at a much
lower cost than other methods. To achieve greater effectiveness with
the BS-15 acoustic repeller, it is necessary to use the distress and alarm
sounds in moderation, since excessive use may make the birds get used
to the sounds, and therefore ignore them. When the birds hear the cry
of a bird of prey followed by a distress call from a bird of the same
species, they will flee for their life.
Sometimes the distress call of an unrelated species may be effective
against a bird of its own species. This is called a “leader species”.
In some situations and places, certain natural sounds work wonderfully
by driving away, for example, seagulls. In other parts of the country,
perhaps due to the different local experiences, seagulls react better to
other natural sounds.
You have to try different sounds to find the one
best suited to the area.
