Can you bring bug spray on a plane?

Yes. Pump or trigger spray insect repellents up to 3.4 oz (100 ml) are allowed in your carry-on liquids bag under the TSA 3-1-1 rule. Full-size bottles belong in checked baggage. Pump sprays travel with less hassle than aerosols.

What insect repellent is best for travel to dengue zones?

Picaridin 20% is the skin repellent most travel clinics recommend for dengue and zika destinations — up to 12 hours of protection against the day-biting Aedes mosquitoes that spread them, with odorless options that won't damage sunglasses or gear. Apply sunscreen first, repellent on top, every morning.

How should I prepare clothing for a malaria-zone trip?

Treat your travel wardrobe with permethrin 0.5% spray at home about 48 hours before departure — it repels and kills mosquitoes on contact and lasts roughly 5 washes. Pair it with a skin repellent at night, and see a travel medicine clinic 4–6 weeks before departure for malaria prophylaxis.
