Here's tips on repellents, toiletries, birdwatching tools, rain gear, and more to keep your footprint tiny.

Insect repellents first, because mosquitoes sandflies ticks are relentless, especially dawn dusk rainy season. Go for DEET-based ones 20-50% concentration, effective longest, or picaridin if you prefer less harsh smell feel. Apply to skin clothing, reapply after sweating or swimming. Natural options like oil of lemon eucalyptus work decent but shorter protection, layer with long sleeves pants. Permethrin-treated clothing huge help, spray on before trip, lasts weeks through washes, repels on contact. Pack a head net for super buggy trails or boat rides. And citronella candle or coils for camp evenings if allowed, but check lodge rules.
