Rentokil Initial Warns About the Growth of Seagulls in Cities and Their Impact on Health and the Urban Environment.

Seagulls, birds traditionally associated with coastlines and the sea, have found a new habitat in Spanish cities that provides them with abundant resources. This adaptation has led to a considerable increase in their population, resulting in a growing problem that affects both the daily lives of citizens and the economy and public health.

According to experts, seagulls have learned to find food and nest in urban environments, where resources are more accessible. This behavior has extended their breeding season and expanded their distribution to inland areas, such as the Community of Madrid, where they were not previously common.

The consequences of this proliferation are varied and concerning. The constant noise and aggression of seagulls—especially during the breeding season—contribute to discomfort in urban areas. Additionally, the accumulation of debris they use for nesting affects the cleanliness of these areas. Their droppings, which are highly corrosive, cause rapid deterioration of buildings, vehicles, and public furniture. For businesses, particularly in the hospitality sector, the presence of seagulls on terraces can deter customers from visiting, resulting in significant economic losses.

On a health level, the situation is equally concerning. Seagull droppings can harbor bacteria and viruses, and the nests create an environment conducive to the proliferation of fungi and mites. This increases the risk of disease transmission, including Avian Flu, Salmonellosis, Histoplasmosis, and Cryptococcosis, particularly when there is contact with contaminated remains.

Historically, controlling seagull populations has relied on traditional methods, such as placing nets and spikes in resting areas or using falconry to scare them away. However, the adaptability of these birds has highlighted the need for a sustained implementation of various techniques.

To effectively address this challenge, Bird Alert has been introduced, an innovative system that allows real-time detection of seagulls using microphones that emit sounds of natural predators to deter them. This device not only individually identifies the birds, adapting its response, but also allows for remote monitoring via mobile devices. The effectiveness of this approach has been demonstrated in various international contexts, from landfills to hospitals, achieving immediate and sustainable long-term results.

In light of the growing challenge posed by seagulls in urban environments, it is clear that innovation and adaptability are key to mitigating their impact and safeguarding both public health and the economic interests of cities.
