Advantages of Using bird Repeller Devices

Date : 31st May 2016

 This standard identifies different types of bird deterrent systems available and includes a brief description of how each system is intended to work by outlining their advantages and limitations.

 Anti-Roosting Wire System, "Pin and Wire" or "Trip Wire": 
-    Used primarily for deterring pigeons.  
-    Consists of a series of parallel wires supported by narrow pins and held under tension by small springs.  The spacing between the wires is intended to prevent pigeons from gaining a strong foothold on ledges.  
-    The wires are sometimes installed at differing heights in order to come in contact with the bird's wings, making comfortable roosting difficult.

   Advantages:

    1.   Causes minimal damage to building.  The narrow stainless steel pins used for support are small enough to be drilled into the mortar joints.  If and when the pins need to be removed, the holes made can be refilled with mortar, avoiding any further damages to the masonry or stone.  In places where this method cannot be applied directly to the building, Plexiglas may be used to provide a means of contact.
    2.   Can last up to 10 years 
    3.   Environmentally safe
Plastic Netting Systems or "Chicken Wire":
-    An old method developed initially for agricultural use, the netting system has been adapted for the protection of buildings.  
-    This system is intended to eliminate the bird control problem by exclusion, preventing birds from nesting in recessed portions of the building, in light wells, or under eaves. 
-    Two fibers:  Polyethylene or Polypropylene is recommended to make the netting.  Unlike other fibers, both of these materials withstand tension without stretching.  Both fibers can hold up to 30 lbs of tension and should be installed holding at least 20 lbs to prevent sags.  Sagging speeds up deterioration and makes the system more noticeable.  Netting to match building colors is available and, if hung correctly, can be fairly inconspicuous.  


   Advantages:

    1.   Suitable for large areas
    2.   Environmentally safe
    3.   Effective against most species of birds
    4.   Can last up to 15 years

Rows of Metal Spires or "Porcupine Wire":

-    A physical barrier repellent consisting of rows of needles or spikes pointing vertically upwards. These spikes are intended to make it difficult for larger birds such as pigeons to land. 
     -   This product is generally used on horizontal surfaces such as ledges and window sills, where birds are known to roost or nest.

 

 Advantages:

    1.   Easy to install
    2.   Long life-span
    3.   Environmentally safe

Ultrasonic’s:

-    Marketed for hearing ranges above 20K Hz; Used to produce high frequency sounds as a means of deterring birds from roosting or nesting in certain locations.

Distress Signal Call Systems:

-    Birds naturally warn other birds of potential danger.  This system intends to mimic this idea by producing sounds that will signal to surrounding birds the danger of coming near particular building.  
-    Its effectiveness depends upon the type of technology.  Birds can differentiate between a real distress -    Distress calls are best suited for use against flocking birds such as starlings which search for a winter roost.  Once the designated spot has been located, the digitized distress calls are played repeatedly sometimes as long as two weeks. 

   Advantages:

    1.   Does not obscure the building aesthetics
    2.   Does not impact, alter or damage the building
