Biting plankton occurrences in Nha Trang and Cam Ranh are common between May and October. It is often triggered by low tides and colder water. Recommended mitigation includes swimming early in the morning or applying coconut oil to the skin before swimming.

For skin reactions causing itching and swelling: apply a cream containing methylprednisolone aceponate (e.g., Advantan) once daily for 5-7 days.

To identify bed bugs in hotels, check for brown spots on bedding/mattresses and blood stains. Bites often appear on wrists, ankles, and neck. If confirmed, move to a different hotel property immediately. Applying hydrocortisone or taking antihistamines like cetirizine can manage itching. Photosensitivity or dermatitis can also mimic bites; differentiation is key.
