bird pest

Pigeons are found is almost every community in America. The population in Fairbanks
has grown overtime. It is quite amazing that these birds have been able to adapt to the
climate conditions. They do this by finding protective sites to roast such as open attics
and the eaves of heated buildings. Naturally pigeons are grain and seed feeders, but they
will also feed on garbage, livestock manure and insects, when food is scare. A major
food source is provided by individuals in our community that feed pigeons as a form of
recreation. Initially this may appear to be a good idea. But with a growing population of
pigeons comes the threat of diseases.
Diseases carried by Pigeons
Pigeon carry diseases that can be transmitted to humans and other animals. They also
cause conditions that encourage growth of disease organisms. Bacterial, fungal,
protozoa, and viral infections can be transmitted. In reviewing literature I found over 40
diseases that can be associated with pigeons. The skin parasites of pigeons, including
mites, fleas, ticks and bugs, may bite people or cause an itchy red rash. These birds also
carry diseases, which can be passed on to other domestic birds and wild birds such as
falcons. A bird of prey feeding on these feral birds can become sick. One way to protect
animal and human health is by controlling these pest birds.
Pigeon droppings
The droppings of pigeons are very alkaline and not only smell bad, but will damage
buildings. As manure accumulates over time, it attracts household pest, such as larder
beetles. Beetles will feed on the droppings in attics and when food supplies get low
move through light fixtures and other openings into the house.
Control Methods
If pigeons have decided to pick your home as an over wintering locations you have
several options for control starting with repellents and exclusion. Use a repellent to get
the pigeons to move to a new location. The most common repellent used is naphthalene
flakes (more commonly known as Moth Balls). As the flakes dissolve and evaporate they
produce a strong odor that repels pigeons. The flakes can be spread on the attic floor at a
rate of 5 pounds per 2000 square feet.
After the birds have moved to a new location, block access to indoor roosts and nesting
sites. Openings to steeples, vents, eaves and attics should be blocked with wood or heavy
screens. Porcupine wires can be put on ledges as a repellent. They are composted of
several sharp prongs. These sharp pointed wires inflict temporary discomfort and cause
pigeons to avoid landing on these surfaces.
Repellents and exclusion get rid of your problem but pass it on to someone else. There
are poisons that may be used only by a certified applicator. With some poisons you have
to worry about the flesh of animals killed with poison being toxic to other organisms that
may feed on the dead birds.
Trapping
If you wish to reduce the number of pigeons in the community, trapping may be a option.
Traps can be easily be built with 2 by 2's and poultry netting or chicken wire. Four to
five birds left in the trap will serve as a decoy to lure more pigeons into the trap. Decoy
birds should be provided with food, water and shelter. Traps must be tended daily and
moved to different locations to remain effective. The Alaska Cooperative Extension has
planned available for individuals interested in building a trap. We also have publications,
which explain the health hazards associated with these birds.
