Starlings were introduced in North America in 1890 by Eugene Schieffelin in an attempt to import every bird mentioned in the works of William Shakespeare. The original 60, released in Central Park, have grown to a staggering 150 million estimated individuals and span from Alaska to Central America as a result of minimal diet restrictions, and the ability to nest almost anywhere. This massive population from such a small genetic stock makes North American varieties of this starling particularly susceptible to widespread outbreaks of disease. Their large flock sizes and fierce territorial nature can also make them a very noisy pest to have in or around your home.
Sparrows, by comparison have become almost completely dependent on human civilization. Oversized populations anchor to large human population centers, far in excess of normal carrying capacities, for the unlimited supply of food as well as the availability of nesting sites. Sparrows tend to move in to a nest rather than carve out their own. Rather than fight with a current occupant, it is easier still to take advantage of empty cavities readily available in modern human homes. Also because of their close association with humans, this species is known for its tendency to carry many human diseases like E.coli, and surprisingly often Salmonella. Recent studies estimate around 13% of house sparrows may carry Salmonella. For comparison, the number of bats that carry rabies is around 1%.
What can we say about pigeons that haven’t already been said? Introduced in 1606, this scavenger found early success and developed large, seemingly boundless populations. Their dense community structure and rapid, year-round breeding cause them to completely take over any structure available from dusty rural barns to busy multiple lane bridges and overpasses. Their foul and often dangerous droppings can paint a floor from corner to corner, or accumulate to stalagmite like piles multiple feet in height. Scavenging and overpopulation also lend themselves to large outbreaks. Pigeons often foster Histoplasmosis, a respiratory disease caused by a fungus, and many different types of exoparasites like mites and lice. Read about pigeon infestation mitigation here.
Get Rid of Birds From Your House
Physical Deterrents – Many problems may be solved using physical deterrents like bird spikes or cables. By discouraging the birds from landing, devices like these eliminate roosting areas, and prevent nesting altogether. Once installed, these devices remain permanent to insure the problem remains at bay long into the future without requiring follow up services. Read more about optical gel bird deterrents here.
Exclusion – In cases where the birds have made their way into your home, we can remove them by “exclusion” similar to how we handle bat issues. “One-way doors” are installed over each entry point. When the birds exit to forage for food and water, the devices prevent them from reentering upon their return. Once we are confident your house is free of birds, we remove our devices and patch the entry points permanently, often utilizing chimney caps, protective screens, dryer vent covers, or metal flashing. These patches are always guaranteed for your peace of mind.
