Birds become a problem to humans when they set up home in our structures – our houses, buildings and monuments. They can also cause problems in rural situations but we will only deal with the urban areas.

No inhumane methods are allowed. Shooting is seldom an option and some methods of trapping and disposal are not acceptable.

Bird droppings are unsightly and over time can cause structural damage due to its chemical make up. There are also public liability issues in regard to bird droppings as they can make walkways and paths directly beneath bird zones slippery. The noises birds make are unwelcome and of greater importance - the likelihood of disease is much higher when there are large bird populations. Some 60 transmittable diseases have been found to have been associated with birds. The diseases range from Histoplasmosis, Cryptococcosis and Aspergillosis and can cause respiratory symptoms. Salmonellosis can be carried by bird droppings. Then too there is the problem of bird lice and most noticeably the odour that a large bird population can create.

PREVENTION METHODS AVAILABLE

There are a range of systems available which deter birds from entering a property, however prior to commencement of any work to exclude birds from a particular site it is critical that the pest manager carries out a detailed survey of the property.

That survey will provide valuable information which will enable the pest manager, in co-operation with the owner or tenant, to tackle some of the root causes of the bird problem. Matters as readily available as food and water, overhanging trees, loose roofing sheets etc.

Each site is different but by using a range of specially manufactured materials most problems can be overcome. Where there are large areas a netting system, anchored to stainless steel cables and then tensioned are ideal.

In other locations spikes, either fibre glass or stainless steel, can be used. The spikes are used for Pigeons and Gulls and the length of the spike is slightly longer than the birds legs when they attempt to land the spike digging into their sides makes them uncomfortable and they fly off.

Spring wire erected near landing areas makes the birds unsure of their footing and they fly off. Timber, Nails, Screws and Wire Netting all have their uses in building out birds. With the right application of materials and types of systems Birds can be excluded from properties permanently.

Subject to the seriousness of the bird problem stronger measures may be taken. However public perception and a whole range of available options will be considered by your Heritage technician when discussing solutions to your problem.
