How to Avoid Mosquitoes and Leeches When Trekking in Quang Binh

When going trekking in the forests and mountains of Quang Binh, mosquitoes and leeches are two "uninvited guests" that can cause a lot of trouble. Understanding them will help you better prepare to avoid them.

Mosquitoes in the Forest

Everyone knows mosquitoes, but deep in the forest, they are even more worrisome. The Aedes aegypti mosquito species is often most active in the early morning and late afternoon, when dew still rests on leaves or dusk falls. Mosquitoes are attracted to our breath, specifically CO₂ gas, sweat, and body temperature. Besides causing itching and discomfort, mosquitoes are also the cause of many dangerous diseases such as dengue fever, malaria, or Zika virus. These diseases not only appear in major cities like Hanoi and Ho Chi Minh City but are also a concern in rural and mountainous areas.

What is a Forest Leech?

Leeches are "cousins" to water leeches; they look a bit scary but are familiar to anyone who has trekked through forests. Normally, land leeches are as small as a toothpick head, but when fully engorged with blood, they can grow as thick as a chopstick tip. They live mainly in damp places with plenty of decaying leaves or dense vegetation, such as the primeval forest of Phong Nha - Ke Bang National Park. During the rainy season, leeches become even more active, latching onto your skin unnoticed. They secrete an anesthetic, so their bite doesn't hurt at first, but by the time you notice them, they are already full of blood. The bite can bleed for a long time and is prone to infection if not cleaned properly.

If you go into the forest without careful preparation, you can easily become a "mobile buffet" for mosquitoes and leeches before you know it. But don't worry, in the next section, Sovaba Travel will guide you on how to prevent them so your trekking trip is complete and enjoyable!  

If you go trekking in the forests and mountains of Quang Binh without adequate preparation, it's very easy to become easy prey for mosquitoes and leeches. Therefore, before setting off, remember to keep these handy tips in mind to make your trip safer and more comfortable!  

General Prevention

• Wear protective clothing: When trekking in the forest, it is best to wear long-sleeved shirts, long trousers, and closed-toe shoes/boots. Choose thick, light-colored fabrics so mosquitoes and leeches find it hard to cling onto. You might think it's hot, but deep in the shaded forest, covering up is much safer.  
• Use insect repellent: This is an essential "weapon." Repellents containing DEET, picaridin, or orange peel oil are very effective in repelling mosquitoes, and DEET also works against leeches. In Vietnam, Remos and Soffell are two popular brands easily found at pharmacies or supermarkets like Pharmacity. Spraying it on your clothing and skin before entering the forest gives you complete peace of mind.

Mosquito Prevention 

• Avoid dawn and dusk: This is when mosquitoes are most active, so if possible, limit walking into the forest or resting in damp places during these times.  
• Use a mosquito net while sleeping: If staying overnight in the forest, especially when camping in a tent or staying at a homestay without air conditioning, remember to bring a mosquito net. Protection while sleeping is the best way to prevent surprise mosquito attacks.  

Leech Prevention

• Avoid sitting or lying directly on the ground: Especially in damp areas with lots of rotting leaves or dense grass. If you need to rest, inspect the surrounding area carefully or find a drier spot.  
• Check your body regularly: After passing through bushes or thick vegetation, remember to look closely at your limbs, neck, and back to see if any leeches have attached. If you spot a leech, do not pull it off forcefully as it can easily cause bleeding; instead, drop salt or vinegar on it so it detaches on its own.  
• Use anti-leech socks or gaiters: These are high, tight-fitting socks designed to prevent leeches from sneaking inside your shoes and attaching to your legs. If you don't have them, you can tuck your trousers tightly into your socks and tie them up.   

Many people apply salt, vinegar, or citronella oil to their feet and shoes to ward off leeches. It sounds simple, but it's very effective, especially when trekking during the rainy season.  

Even with careful prevention, when going deep into the forest, leeches and mosquitoes may still find ways to attach themselves to you. If you unfortunately get bitten, don't worry too much—handle it properly to avoid infection and other health issues!

When Bitten by Mosquitoes

• Clean the bite: First, wash the bite area thoroughly with soap and clean water to prevent bacterial infection. If it's very itchy, you can apply anti-itch cream or apply ice to soothe it. If you have sensitive skin, try applying a gentle soothing lotion or calamine cream to cool the skin.
• Monitor your health: If after a mosquito bite you experience a high fever, rash, or severe headache, seek medical attention at the nearest healthcare facility. These symptoms could be signs of dengue fever or malaria, especially when trekking in high-risk areas.

When Bitten by Leeches

Leeches attach to skin by secreting an anesthetic and an anticoagulant, so when they bite, we don't feel pain right away. Do not attempt to yank them off forcefully, as this can tear the skin and cause heavier bleeding. Instead, you should:

• Sprinkle a little salt, squeeze a few drops of lemon juice, or drip vinegar onto the bite site, and the leech will detach on its own.
• If you don't have these items, you can use a hard card or a blunt knife to gently slide under the leech's mouth parts to remove it slowly.
• Clean and bandage: After removing the leech, wash the wound thoroughly with soap and clean water. If medical alcohol is available, gently disinfect and bandage the bite to avoid infection. The bite may bleed for a prolonged period due to the anticoagulant in the leech's saliva, but don't worry—just apply a firm bandage and gentle pressure to stop the bleeding.
• Monitor for signs of infection: If you notice the wound becoming red, swollen, oozing pus, or if you feel feverish and fatigued, visit a medical facility for timely examination and treatment.

Mosquitoes and leeches may be small, but they can cause quite a hassle, so when going trekking in the forests and mountains of Quang Binh, remember to prepare carefully and treat bites promptly. Thorough prevention and knowing how to deal with bites will give you peace of mind to fully enjoy your nature exploration journey.
