Pest birds can become a problem once they find an access pathway in a building as they are searching for food or for shelter. They can disturb the space they settle in and they can also cause health issues by spreading disease in the area.
Birds can cause damage, can provide an infectious risk, and can lead to the occurrence of additional insects that can damage textiles or can cause bites. Nevertheless, the main visible problem remains bird droppings.
The main elements that alert you about having a problem with birds are bird droppings, nests, various insects such as fleas and flies, and odors. As the birds live comfortably in any city or urban location, they tend to look for food everywhere, usually being social and living grouped in larger numbers. To be able to reduce the control risk of pest birds, you first need to know what type of specie you are dealing with, as you will need to adapt to several details when dealing with an infestation, or when trying to prevent one from happening.
Under optimal conditions, the specie known as pigeons can breed all year round. Pigeons carry and can transmit diseases such as salmonella to humans. They were also known for carrying diseases such as psittacosis Chiamdiosis, which is a diseases similar to influenza and pneumonia.
One of the most widespread animals on the planet, the invasive sparrow, takes full advantage of the opportunities humans supply. They are aggressive toward native songbirds in competition for resources, and can invade the crevices of homes such as dryer vents, building crevices, attic vents, the areas around window-mounted air conditioners, barns, sheds, and chimneys.
Crows are native birds throughout North America, but they may also be found on all temperate continents worldwide, with the exception of South America. These are large, intelligent, jet-black birds which can cause disturbance through their loud, hoarse voices. They’re well-known destroyers of corn crops, with fruit and plant matter making up about two-thirds of their diet.
Prevent damage done by pigeons
They are responsible for millions of dollars of damage each year in urban areas. The uric acid in their faeces is highly corrosive. Also, debris from roosting flocks can build up, backing up gutters and drains thus causing damage to roofs and other structures. Besides physical damage, the bacteria, fungal agents and ectoparasites found in pigeon droppings also represent a health risk. Pigeon infestation often occurs on rooftops of buildings, window sills, ledges and other convenient surfaces. The corrosive droppings then deface walkways, equipment, and vehicles below.
The best solution for pigeon problems, is complete exclusion with a mesh, bird wire or bird spikes. Flock dispersal alone is not a long term solution especially in medium-heavy pressure situations like when there are food/water/shelter sources at the site. Prevent pest pigeons from landing on surfaces by installing pigeon control spikes which are 100% effective everywhere installed. For preventing them to enter enclosed areas, you can use bird netting systems.
Pigeons often accumulate in public areas like parks and plazas, attracted to discarded food & trash left by tourists and other passersby. By keeping a clean area around your building or in your yard you can have very effective results in keeping pigeons away.
Prevent damage done by sparrows
Their ability to nest in urban structures, eat urban scraps and have a large breeding capacity are some of the sparrows’ adaptive traits. Gutters and drainage pipes clogged with sparrow nests can backup and cause extensive water damage and fires have been attributed to electrical shorts caused by machinery housing sparrow nests. The same as with the pigeons, feces buildup and the uric acid in their droppings can cause structural damage.
These noisy sparrows crowd out native songbirds at bird feeders, bird baths, and bird houses. They gather in large numbers making messes, in trees above cars, along building ledges, and they can even invade attic spaces or get inside of walls if there is an opening. House sparrows often evict other birds from nest holes, and defend their nests from other birds with surprising aggression.
House sparrows eat massive quantities of insects and spiders, including mosquitoes, and bring avian life to some of the harshest urban living environments.
However, should you be dealing with them as pests, you can use spikes to prevent them from landing on surfaces. Also chemical repellents can be used, in order to deter birds from landing on a particular place. After a longer period of time of using the repellent, the birds tend to avoid the area and so will no longer appear.
Blocking bird access by installing missing windows, or filling in plugging holes in walls or installing protective nets over larger holes can also do the trick. You can also set up traps with nets that are installed in a high place and where the birds get caught in their flight.
Prevent damage done by crows
Crows have a scavenger’s diet and will eat a wide variety of things. Such food items include insects, frogs, small snakes, eggs, mice and dead animal carcasses. They will also eat newly planted crops such as corn and other farm crops.
Should your crop suffer from a crow invasion, hunting or capture them will be very difficult as the crows are social birds and the flock is in constant communication. They have been found to not only use, but create tools. Crows are capable of remembering and recognising human faces, can count numbers, and are also skilful at solving puzzles. Crows are known to harass both humans and animals, being even aggressive toward larger birds including hawks, herons, or owls.
In order to repel crows away, you have to make the area seem threatening by using anti bird cannons. Naturally-recorded predator sounds create the illusion that the area is not safe. Visual deterrents, like scarecrows work best in combination with other tactics, such as netting and also making the crops or other food sources taste bad.
