Pigeons and sparrows are two common bird species that can sometimes become a nuisance in urban and suburban areas of New Zealand. As a pest control company, it's important to understand their biology, habits, and potential problems, as well as the various control methods available for both species.
Pigeons (Columba livia):
Pigeons, also known as rock doves, are native to Europe, Asia, and Africa, but have been introduced to New Zealand and other countries worldwide. They are well-adapted to urban environments and often congregate in large numbers around human settlements.
Problems caused by pigeons:
1. Damage to property: Pigeons can cause significant damage to buildings and structures, as their acidic droppings can corrode materials like metal, stone, and concrete.
2. Health risks: Pigeons can carry and transmit various diseases, including salmonellosis, histoplasmosis, and psittacosis, which can pose a risk to human health.
3. Noise and nuisance: Pigeons can be noisy and create a mess with their droppings, feathers, and nesting materials, which can be unsightly and unhygienic.
Sparrows (Passer domesticus):
House sparrows are small, social birds native to Europe, Asia, and North Africa. They were introduced to New Zealand in the 19th century and have since become widespread and abundant. Sparrows are highly adaptable and can thrive in a variety of habitats, including urban areas.
Problems caused by sparrows:
1. Crop damage: Sparrows can cause significant damage to crops and gardens, as they feed on a variety of seeds, fruits, and vegetables.
2. Nesting and property damage: Sparrows can nest in roof spaces, gutters, and other building cavities, causing damage to insulation and other materials.
3. Health risks: Sparrows can carry and transmit diseases, such as salmonellosis and avian mites, which can pose a risk to human health.
Pest control methods for pigeons and sparrows in New Zealand:
1. Exclusion: Physical barriers like bird netting, bird spikes, and mesh can be installed to prevent pigeons and sparrows from accessing nesting and roosting sites.
2. Trapping: Live traps and baited traps can be used to capture and remove pigeons and sparrows from the affected area.
3. Repellents: Chemical and natural repellents, as well as visual and auditory deterrents, can be employed to discourage pigeons and sparrows from settling in a particular area.
4. Population control: In some cases, controlling the population through egg and nest removal, or even humane culling, may be necessary to manage the problem effectively.
As a pest control company in New Zealand, it is crucial to follow all local regulations and guidelines when implementing bird control measures. Additionally, it is important to educate customers about the importance of maintaining a clean and tidy environment, as this can help discourage pigeons and sparrows from settling in the area.
