As the National Day holiday wraps up, travelers are returning to their daily routines. However, you might not be coming back alone—mosquitoes could be hiding in your luggage, ready to invade your home. Uninvited guests like Aedes mosquitoes can transmit diseases such as dengue fever and chikungunya, posing significant health risks. Here's a straightforward guide to ensure you and your home remain mosquito-free during your return journey.
Before you leave: Pack smart
Begin by inspecting your belongings. Check jackets, backpacks, and other items to ensure no mosquitoes or their eggs are "stowing away." Upon your return, wash all worn clothes promptly. Pack light-colored, long-sleeved shirts and pants, as dark colors tend to attract mosquitoes. Additionally, carry effective insect repellents containing ingredients like DEET or picaridin. A 10% DEET-based repellent lasts about 4–6 hours, while a 20% picaridin repellent can provide protection for up to 8 hours.
On the way: Stay protected
Timing is crucial! Aedes mosquitoes are most active during early morning (7–9 a.m.) and late afternoon (4–7 p.m.). Avoid lingering near shaded areas, grassy spots, or stagnant water during these peak times. Apply repellent to exposed skin, such as your arms, ankles, and neck, and reapply every 2–4 hours, especially if you are sweating. For additional protection, wear loose-fitting clothing with tightened cuffs and pant legs to prevent mosquitoes from sneaking in.
Back home: Stay vigilant
After arriving home, monitor your health for the next 14 days. Be alert for symptoms such as sudden high fever, severe headache, joint or muscle pain, or rashes—common signs of dengue or chikungunya. If you experience any of these symptoms, seek medical help immediately and inform your doctor about your travel history.
Next, eliminate mosquito breeding sites around your home. Clear stagnant water from pots, buckets, and other containers, scrubbing them thoroughly. Change the water in vases or pet bowls every 3–5 days. Indoors, use mosquito nets, window screens, or electric mosquito repellents. When using insecticide, target hidden spots like behind curtains or under beds.
A smooth return trip sets the stage for a fresh start. By following these simple steps, you can protect your family and community from mosquito-borne diseases. Let’s prevent mosquitoes from hitching a ride—stay aware, stay healthy!
