Overview

• An unseasonably mild winter and abundant spring rainfall have accelerated mosquito breeding, sparking early outbreaks in Catalonia and beyond.
• Catalonia has activated its arbovirosis protocol to monitor and curb mosquito-borne diseases after last year’s dengue cases.
• Officials recommend AEMPS-approved topical repellents, mosquito nets and the removal of standing water to lower disease and allergy risks.
• Widely shared home remedies—such as lemons studded with cloves and potted citronella, lavender and basil—remain popular despite limited scientific backing.
• Non-chemical commercial products, including Amazon’s beer- or cola-baited BSí wasp trap, are gaining traction for capturing wasps and flies.
