As with most tropical islands there is the risk of insect bites from mosquitoes and sand flies. So be sure to arm yourself with insect repellent especially if you will be visiting between September to November.

Mosquitoes can be a nuisance in Antigua, particularly during the "wet season" which typically runs from June to November. As a tropical island with lush vegetation and varying terrain, the presence of mosquitoes is a natural occurrence, especially at dusk and dawn. In 2026, health authorities on the island continue to manage and monitor mosquito-borne illnesses such as Dengue fever through regular fogging and community awareness programs. To minimize bites, travelers are advised to stay in accommodations with screened windows or air conditioning and to use an insect repellent containing DEET, Picaridin, or oil of lemon eucalyptus. If you are staying near stagnant water or in more rural, inland areas, the mosquito presence will be significantly higher than at the windy, beachfront resorts on the coast where the constant trade winds help keep the pests away. Most high-end resorts also perform their own pest control on the grounds, but it is always wise to pack lightweight long-sleeved clothing for evening dining to ensure your vacation remains itch-free.
