Mosquitoes are a common nuisance in Costa Rica, especially in areas like the Ostional Wildlife Refuge. The warm and humid climate provides the perfect breeding grounds for these pesky insects, leading to high populations throughout the year.

In addition to being annoying, mosquitoes in Costa Rica can also pose a health risk to both locals and tourists. The country is home to various mosquito-borne diseases, such as dengue fever, Zika virus, and chikungunya. These diseases can have serious consequences if not treated promptly.

Visitors to the Ostional Wildlife Refuge should take precautions to protect themselves from mosquito bites, such as using insect repellent, wearing long sleeves and pants, and staying indoors during peak mosquito activity times. It is also important to be aware of any travel advisories regarding mosquito-borne diseases in the area.
