The island of Mallorca has experienced an increase in biological nuisances. Initially, reports focused on a surge in summer pests, specifically the spread of invasive ants and tiger mosquitoes.

This was followed by reports from tourists in Mediterranean coastal areas, such as Illetes, Cala Comtessa, and Playa de Palma, regarding painful bites from small fish. Experts suggest species like sargus or lufar may be responsible, potentially driven by rising sea temperatures which increase marine metabolism and foraging activity near humans.
