French towns urge residents to curb tiger mosquito spread

The tiger mosquito, now common throughout the Bordeaux metropolitan area and beyond, is causing health concerns each summer. Because broad insecticide spraying is prohibited, only the state can authorize limited use when a clear health risk is identified. The regional health agency therefore carries out targeted interventions, while municipalities such as Eysines install anti‑mosquito stations, bat and bird nesting boxes, and provide a demoustication centre for residents to report breeding sites.

Public health officials stress simple personal actions: securely cover water sources, empty containers that collect rainwater, clean gutters, and maintain outdoor water points. Complementary natural repellents are also promoted. Five aromatic plants—citronella, geranium rosat, lemon basil, peppermint, and rosemary—release volatile oils that interfere with mosquito sensory receptors. When placed within a metre of sitting areas and regularly brushed or crushed, these plants can create a localized deterrent zone, provided standing water is eliminated.

Together, coordinated municipal measures and household‑level practices aim to limit mosquito breeding and reduce biting incidents during the summer months.
