The malaria-zone checklist, in departure order
Malaria prep has a timeline, and the most important item can't be bought in a store. Work backwards from your flight and nothing gets missed.
No spray replaces the pills. In real malaria country, prescription prophylaxis from a travel medicine clinic is the load-bearing layer — everything on this page reduces bites, but only the medication protects you when a bite gets through. If you take one action today, book the clinic appointment. The rest of this checklist hangs off that date.
Dengue prep is a habit; malaria prep is a project plan. The mosquito behind it — Anopheles, a dusk-to-dawn feeder — sets your nightly routine on the ground, but the decisive moves happen weeks before departure. Here's the whole sequence, keyed to the calendar.
The countdown
WKS
Book the travel medicine clinic
A clinician matches the antimalarial to your exact route — resistance patterns differ by region — and your health profile, and folds in any vaccines (yellow fever, typhoid) the itinerary needs. Four to six weeks out isn't bureaucratic padding: some regimens and vaccines need lead time to start working.
Why it can't slip: certain prophylaxis schedules begin 1–2 weeks before you enter the risk zone.WKS
Fill the prescription and set reminders
Get the pills in hand early and load the schedule into your phone — including the tail after you return. Missed doses are how protected travelers become case reports.
The classic mistake: stopping the pills when you land home. The parasite doesn't respect your return date — finish the course.HRS
Permethrin-treat the travel wardrobe
Evening shirts, trousers, socks, a buff — sprayed outdoors, dried completely, packed treated. The fabric now kills mosquitoes on contact for roughly 5–6 washes: your whole trip. Step-by-step at our sister site: treating clothes with permethrin.
Why 48 hours: full drying time plus a margin — and wet permethrin must never travel or meet the family cat.DAY
Pack the night kit
Skin repellent (20% picaridin or 30% DEET), a backup, long loose layers for evenings, and — if your lodging is rustic or unknown — a permethrin-treated bed net. Screened lodges and city hotels usually cover the net for you; tents and homestays don't.
Packing note: the repellent travels carry-on at 3.4 oz; the treated clothes fly checked, already working.GROUND
Run the dusk-to-dawn routine
Sundown is your cue, every day: treated long sleeves and trousers on, repellent on the skin that's left out (ankles, wrists, neck), then sleep behind a net, screens, or sealed air-con. Dawn game drives count as night — dress for them the same way.
Timing beats brand: a mediocre repellent applied at 17:45 outperforms a perfect one still in the daypack at 19:30. Our calculator tells you if last application carries you through dinner.+1 YR
Respect the fever rule
Malaria can incubate for weeks — occasionally months. Any significant fever after malaria-zone travel is malaria until a test rules it out. Say where you've been, out loud, to every clinician you see.
Why it matters: early treatment is highly effective; late diagnosis is the dangerous version. This line is the checklist's cheapest life-saver.Layer logic: why every piece stays in
It's tempting to treat this as either/or — pills or repellent or nets. The layers exist because each catches what the others miss: the net covers the hours you're unconscious, treated clothing covers dinner, repellent covers exposed skin, and prophylaxis covers the bite that got through anyway. Travelers on all four layers stack small percentages into very good odds. If your trip mixes malaria country with dengue cities — a safari-plus-beach classic — you'll also want the day-shift routine; same kit, opposite clock.

Can I skip the pills if I'm careful with repellent?
No. Bite prevention lowers the count; it can't guarantee zero, and one infective bite is enough. Prophylaxis is the layer that catches the miss — and it's prescription-matched to your route's resistance patterns, which no store product replicates.
When do malaria mosquitoes bite?
Dusk to dawn — the mirror image of dengue's day-biters. That's why this checklist concentrates on evenings and sleep rather than breakfast-time repellent.
Fever after I'm home — how seriously do I take it?
Completely. Get tested promptly and name your destinations to the clinician. Malaria's early symptoms imitate flu, incubation can run weeks to months, and the difference between early and late treatment is the whole ballgame.
