Mallorca, known for its nature and sunny beaches, is increasingly facing new challenges due to climate change. It's not just droughts and heatwaves that are causing the island problems - the spread of invasive pests is also a growing threat. From agriculture to urban areas: The problem has many faces.
Cockroaches: a growing urban problem
Long a problem in the cities of Mallorca, cockroaches are on the increase due to the rising temperatures and milder winters. Especially in Palma, but also in smaller towns and villages, residents are increasingly reporting sightings of these unwanted guests. The spread is facilitated by outdated sewage systems and a lack of hygiene. Local authorities have already reacted: they are increasingly using pest control measures and working on long-term solutions.
Asian hornet: Threat to bees and biodiversity
The Asian hornet (Vespa velutina), originally native to Southeast Asia, has reached Europe in recent years and is also spreading to Mallorca due to the changing climate. Their preference for bees makes them a serious threat to beekeeping on the island. "Without bees, we not only lose honey, but also important pollinators for agriculture," explains a representative of the Balearic Ministry of Agriculture. Measures such as detecting and destroying nests are being intensified.
Citrus thrips: a danger for Mallorca's orange groves
The citrus thrips (Scirtothrips aurantii) is a major concern in rural areas. This invasive pest attacks citrus plants and causes considerable damage, particularly in Sóller and Fornalutx. The infestation leads to deformed fruit, which severely affects sales. To reduce the pest pressure, farmers rely on ecological pesticides and close monitoring.
Pine processionary moth: health hazard and forest damage
The pine processionary moth (Thaumetopea pityocampa) is no longer an unknown guest in the pine forests of Mallorca. Its caterpillars have poisonous hairs that can cause skin rashes and respiratory problems on contact - a danger to humans and animals. The warmer winters have led to a sharp increase in the population, so new programs have been launched to contain it.
Fire ants: A new invasive threat?
The red fire ant (Solenopsis invicta) is another pest that could establish itself on the island. Their painful stings and aggressive behavior pose a danger to humans and animals. They can also cause damage to agricultural crops. Initial sightings in southern Europe have alarmed experts, who are calling for preventative measures to be taken on the Balearic Islands.
Solutions and prevention: a joint effort
Combating these pests requires cooperation at all levels - from government agencies and environmental organizations to the inhabitants of the island. Preventive measures such as the introduction of more resistant plant varieties, the modernization of sewage systems and educating the population are crucial to containing the pests.
The state government is also working to promote the use of environmentally friendly pest control methods. Experts agree that Mallorca can only meet these new challenges through a combination of prevention, monitoring and rapid response.
