Are there mosquitoes on the Amalfi Coast? Yes, on the terraces.

Yes. The Asian tiger mosquito lives along the whole coast, and it waits on the terraces, in the hotel gardens and in the lemon groves where visitors spend their days, from Positano and Ravello to Sorrento and Anacapri. It bites by day, night biters take over after dark, and August and September tend to bring the most. Disease is a small part of the picture, with a single West Nile case in Salerno province in 2026 and a 2-case dengue cluster on Ischia in September.

Terraces, gardens and lemon groves

The European Centre for Disease Prevention and Control (ECDC) says the tiger mosquito is established in most of Italy below about 2,000 feet (600 m), which takes in the coast's terraced towns. It tends to breed in plant saucers, cisterns and garden containers, so a terrace lined with potted plants suits it well. Forum posters say mosquitoes are fewer right by the sea than inland, turn up wherever there are plants or bushes, and are worst in the evening and after dark.

Put repellent on your ankles and arms before a garden lunch, then again before a terrace dinner. Picaridin 20% and DEET 20–30% both work. Many rooms open straight onto a terrace and tend to lack screens, so choose one with air conditioning and sleep with the doors shut, or bring a plug-in vaporizer.

June is the easiest month. Bites build through July and, by travelers' accounts, peak in August and September, which fits the late-July tiger mosquito peak in the northern Italy data ECDC cites. Late September and October nights are cooler and bring fewer mosquitoes, though not none. The tiger mosquito is out from May, so a spring trip still calls for repellent on warm afternoons.

West Nile near Naples, dengue on Ischia

The Amalfi Coast, from Positano to Maiori, is in Salerno province, while Sorrento, Capri and Ischia belong to Napoli province. Italy's national health institute (ISS) counted 41 locally acquired West Nile cases in Campania in 2026 as of October 21, with 22 in Caserta province, 18 in Napoli and 1 in Salerno, a blood donor. In 2025 Campania had 133, including 80 in Napoli province and 8 in Salerno, according to ECDC and the European Food Safety Authority. No town breakdown is published, so it isn't known whether any were on the coast or the islands. West Nile travels on Culex mosquitoes, which bite in the evening and at night. Most infections cause no symptoms, and ECDC notes that severe illness falls mostly on people 65 and older.

Ischia had the first locally acquired dengue in Campania in ECDC's records, a 2-case cluster with onsets between September 15 and 26, 2026. ECDC still listed it as active on October 21, because it keeps a cluster open until 45 days after the last onset. ISS reported no new onsets in the 24 days to October 20. Campania has never had local chikungunya, and Salerno province had no local dengue or chikungunya from 2023 to 2026. Dengue spreads through the daytime tiger mosquito, so the terrace routine covers it.

CDC has no travel notice for Italy and recommends no malaria medicine, and the yellow fever vaccine is neither recommended nor required. The Italy briefing covers the country's 2025–26 outbreaks in full.

What travelers report

Paraphrased from TripAdvisor threads and linked so you can read them in full. None is dated, and bites on this coast vary a lot from one person and one terrace to the next.

• Amalfi Coast · September

  In an older thread, one poster said they were eaten alive in September and told people prone to bites to cover up in the evening and use a repellent; another said their group of four had hardly any trouble with mosquitoes on two trips. TripAdvisor ↗

• Maiori · late September

  A reply said the cooler nights of late September mean fewer mosquitoes, though not none, for people who usually get bitten. TripAdvisor ↗

• Positano (Path of the Gods)

  In a thread about hiking the Path of the Gods, a poster mentioned that mosquitoes had been out quite heavily recently and advised bringing whatever helps with bites. TripAdvisor ↗

One rule outlasts the trip. A fever, rash or joint pain during or within two weeks after the trip means a doctor visit, and you tell the doctor you were bitten by mosquitoes in Campania.
