The presence of several birds together with a lot of droppings is considered a great nuisance just as it poses hazards on health, property and even on the safety during the people’s everyday activities.
Birds, their droppings and even their nests can harbor over 60 types of disease-causing micro- organisms, which can be passed to humans and other animals through air (from the dried droppings) and direct contact. These viruses include West Nile virus and bird flu virus. The birds and their nest can also host mites and other parasites. And since these animals are persistent enough to defend their territories if they have been allowed to inhabit the place for a long time, then the people’s chances of exposure to and contraction of the diseases are increased.
The bird droppings can even cause seemingly absurd but equally dangerous hazards such as slipping of people who might step on them. Besides, the bird droppings are also highly acidic, and thus are capable of corroding and wearing away paint, wood, steel, concrete, tile and shingles. These birds can also indirectly affect businesses within their habitat vicinity. Their droppings, being corrosive, can ruin store signs and other facilities in the businesses, giving the establishments a dirty, soiled look. Consequently, the customers might think that the same shoddy image of the facilities speaks for the status of the business itself.
As solutions to the problem imposed by these tweeting animals, bird control was introduced. Generally, there are four main types of bird control: visual deterrents, taste aversion, barriers and sound-repelling devices, all of which have their own good and bad sides.
Controlling the aviary
An example of a visual deterrent is a scarecrow which has long been used to scare birds away from rice fields. Thus, this type of bird control pertains to the use of the scarecrow and other materials such as plastic owls and shiny tapes that are a pain to the bird’s eye. The only downside of this method is that birds do have the ability to realize that the owl is plastic and immobile, although the level’s not as good as a human’s.
Taste aversions are chemicals applied especially to garden plants to suppress the birds’ great vegetarian appetite This technique is effectual; however, there is a need for regular re-application of the chemicals.
Perhaps most common among the bird control methods, barriers such as spikes, chemicals and bird nets to keep them away from perching on your backyard beams and ledges.
Lastly, sound-repelling devices are outdoor devices which produce ultrasonic sounds that are only audible to birds and other animals with an extreme hearing frequency range. These devices tend to simulate distress calls, predator calls, and other loud, bird-annoying sounds, all of which are unnoticed by humans. These are very effective, but are also very expensive.
If the birds have been living in your place for a couple of bird generations, they have to be scared away, although it’s not easy because, as what was mentioned, birds are quite defensive of their nests and driving them away won’t make them any less stubborn. But after driving them out, there are certain safety measures to be observed. Clean up the whole area but make sure that you are wearing gloves to protect yourself from diseases. If you have a compromised immune system, try to ask someone else to do it for you. Disinfect the area using either bleach or ammonia, and water afterwards and then put up barriers or others to keep the birds away because they will come back and try to build a nest again.
