Packing mosquito repellent for Bali? Start with the active ingredient and readable directions, not the tropical picture on the bottle. DEET and picaridin are two established options included in CDC guidance. Follow the directions for your particular product, including reapplication and age restrictions. Do not borrow a timing rule from another bottle or assume that more product always means a better plan. When you need both, apply sunscreen first and insect repellent second, following each label. Keep them accessible in your day bag. They do different jobs, so applying one does not replace the other. Bite prevention matters during the day as well as at night. Include garden breakfasts, shaded walks and waiting outdoors in your plan. Do not save your only precautions for the evening restaurant. Look at the screens and doors you will actually use. Ask about suitable sleeping protection if the room is open to the outdoors. Protective clothing and accommodation measures complement repellent rather than replace it. Review current Indonesia travel advice before departure, especially when personal circumstances affect travel decisions. The full guide below turns these steps into a compact packing list and a practical daily routine.
