Are there mosquitoes in Bermuda? A few, mostly in the garden.
The CDC lists no dengue, Zika or malaria for Bermuda. The Asian tiger mosquito bites by day in shady gardens, porches see a few bites on still, humid summer evenings, and the sea breeze keeps most beaches clear.
Yes, but not many, and the CDC lists no mosquito-borne disease for the island. The one you're most likely to meet is the Asian tiger mosquito, which bites by day in shady gardens. Porches see a few bites on still, humid summer evenings, and a sea breeze keeps most beaches close to bite-free.
No dengue on the CDC's list
The CDC's traveler page for Bermuda lists no dengue, Zika or malaria, and the CDC neither recommends nor requires a yellow fever vaccine. Chikungunya has shown up only in travelers. Three imported cases were confirmed in 2014, all in people who had been to affected Caribbean countries, and the Department of Health found no local spread. Bermuda's Royal Gazette has recalled a dengue outbreak in 1942, which followed the discovery of more than 3,000 mosquito breeding sites.
The Department of Health works with doctors and regional partners to watch for imported cases, given frequent travel to the Caribbean, and it has noted that the tiger mosquito can spread chikungunya. Its Vector Control team sets traps aimed at that species. For a visitor, that leaves bites as a comfort issue.
Summer bites: gardens, porches and still evenings
The Asian tiger mosquito bites in daylight, with peaks in the morning and late afternoon. In Bermuda the bites come mostly in gardens, on porches and in shady, sheltered spots after rain, on still, humid days. Complaints cluster in the humid late summer, and August has a reputation as the buggiest month. Beaches with a sea breeze are mostly bite-free, and sand fleas and no-see-ums, though present, rarely bother visitors.
For a June–September trip, put repellent on before an afternoon in a garden or dinner on a porch, reapply after a swim, and close the screens at night when there's no breeze. Our repellent timing calculator gives a reapply schedule for a long day out, and families can check our age-by-age guide for kids. Spring and fall trips, around May and October, tend to be milder.
Where you're going
Here is how the main stops compare for a June–September trip.
Royal Naval Dockyard & the cruise port
No local dengue to plan around on a port stay. Expect occasional mosquitoes on still evenings, so carry repellent for dinner ashore.
Horseshoe Bay
A south-shore beach with a steady sea breeze, which keeps biting insects down. Sand fleas and no-see-ums tend not to be a problem on Bermuda's beaches.
Hamilton
The capital and ferry hub. Expect a few mosquitoes on humid evenings, as elsewhere on the island; repellent before an outdoor dinner covers it.
What travelers report
Paraphrased from forum threads and linked so you can read them in full. None is dated, and a breezy week or a still, humid one changes the picture.
- Bermuda (general; Flatts Village hotel) · August
Most replies said biting insects are rarely a bother and credited the near-constant sea breeze and lack of standing water. One poster had problems only in August, when it was very humid, and another described bites on a porch at a Flatts Village hotel. TripAdvisor ↗
- Somerset rental house · sunrise, sundown, after rain
A visitor with several bites at a Somerset rental house wondered whether mosquitoes, sand fleas or bed bugs were to blame. Replies pointed to sand fleas or no-see-ums, which come out at sunrise and sundown and after rain. TripAdvisor ↗
- Bermuda beaches
A poster reported blisters from sand flea bites, but several replies said sand fleas exist in Bermuda without being a problem, and that no-see-ums are not a problem either. TripAdvisor ↗
The Bermuda kit
- Picaridin 20% travel sprays: odorless, layers over sunscreen and easy to carry for gardens, porches and outdoor dinners. One 3.4 oz bottle covers about a week of daily use for one person.
- Oil of lemon eucalyptus 30%: the EPA-registered plant-based alternative if you prefer one. Not for children under 3.
One rule outlasts the trip. Any fever during or after your trip means a doctor visit, and you tell them you were in Bermuda. If you stopped in the Caribbean on the way, mention that too.
Traveler questions
Is there dengue or Zika in Bermuda?
The CDC's Bermuda page lists neither, and it lists no malaria. Chikungunya has appeared only as three imported cases in 2014, in people who had traveled to affected Caribbean countries, with no local spread. The Department of Health watches for imported cases, since the island's tiger mosquito can carry chikungunya.
Will mosquitoes bother me at Horseshoe Bay?
Probably not much. Beaches with a sea breeze are mostly bite-free in Bermuda. Bites are more likely in gardens, on porches and in shady, sheltered spots after rain, on still, humid days, and late summer is the buggiest stretch.
Are there sand fleas or no-see-ums in Bermuda?
Both are present, and visitors say they rarely cause problems. No-see-ums bite low on the legs at dawn and dusk, and a breeze grounds them. If your ankles get bitten at a rental house, repellent on your lower legs before sunset is the fix. Our Barbados sand fly guide explains the insect.
Does the CDC recommend malaria pills or a yellow fever vaccine for Bermuda?
No. The CDC lists no malaria medicine for Bermuda, and a yellow fever vaccine is neither recommended nor required for entry.
