That’s why we’ve compiled this list of Vietnam’s most common bugs and insects to watch out for, and where they can be found. So you can be prepared for what to expect when visiting this beautiful country.
20 Bugs & Insects in Vietnam That Bite & Sting
1. Bumble Bees
Bumble bees are a common sight in the jungles of Vietnam. They range from black to yellow, and their bodies are covered with dense hair which gives them a fuzzy appearance. Bees are generally found in shrubs or trees where they build their nests by burrowing into the side of the bark.
The sting of a bumble bee can be painful and itchy, but it doesn’t usually need to be treated. However, if you have an allergy to bee stings or if your skin becomes red and swollen after being stung, then you should seek medical attention immediately because it can cause severe reactions if left untreated over time.
2. Vietnamese Giant Centipede
The Vietnamese giant centipede is one of the largest species of centipede in the world and can grow up to 8 inches long! These creatures are usually found under rocks or logs in forests, caves, grasslands, and farms. They are also common in villages and homes because they feed on cockroaches, worms, and termites.
The insect’s venom contains toxin that can cause pain, swelling, and tissue damage at the bite site. Although the bite is painful, it’s not considered life-threatening unless it becomes severely infected. If you get bitten by a Vietnamese giant centipede, you should seek medical attention immediately because it can be fatal if left untreated, mainly if a severe allergic reaction occurs.
Hornets are a type of wasp, and their bodies are black or brown, with yellow-orange stripes, thin waists, prominent eyes, and a stinger at the end of their abdomens. They can be found all over Vietnam, but they’re most common in the northern and mountainous regions of the country. These insects usually build their nests on tree branches, homes, and buildings.
If you get stung by a hornet, you may experience pain similar to a bee sting. The venom injected into your skin will cause swelling, redness, and swelling in your lymph nodes.
See a doctor immediately if you feel like that pain is getting worse or experience shortness of breath or difficulty breathing. They can prescribe an antihistamine or steroid cream to help reduce swelling and itching.
4. Fire Ants
Fire ants are stinging insects that can be found all over Vietnam. They are small, red-orange in color, and have thin waists and six legs. These common Vietnam bugs can be found under rocks, logs, or debris near their nests. They are usually found on the ground, but they can also be found on trees and other vegetation.
Fire ants have a painful bite that can cause swelling, itching, pain, and burning sensations at the site of the bite.
While most people experience only mild symptoms after being bitten by fire ants, some may develop an allergic reaction. It is essential to treat your wound with an antiseptic cream or an antibiotic ointment as soon as possible after being bitten by a fire ant so that you don’t get an infection from it.
Yellowjackets are wasps that are found throughout the world, including in Vietnam. They have a long, thin body that is brownish-yellow in color, a black-and-yellow banded tail, and elongated wings.
Yellowjackets are often found in areas with lots of vegetation, including forests, grasslands, and woodlands. They are commonly found along the edges of parks and gardens in urban areas.
These Vietnam bugs have a painful sting that can cause swelling. The sting is usually not dangerous but causes an allergic reaction if you’re allergic to it. If you get stung by a yellow jacket, apply ice packs or cold compress to reduce swelling. If you suffer a severe allergic reaction to their venom, you may need medical attention immediately because this may indicate an infection has set in.
6. Bed Bugs
Bed bugs are small, flat insects that feed on the blood of humans and animals. They are reddish-brown in color, oval, wingless, and have flat bodies which enable them to hide in cracks and crevices. Bed bugs are often found in beds but may also be found in nightstands, headboards, dressers, carpeting, floors, and walls.
The bite of a bedbug isn’t painful or itchy at first. It usually takes a few days for the bite to develop into itchy red dots or bumps that resembles a mosquito bite. If a bed bug has bitten you, wash the area with soap and water and put some ice on it for about 15 minutes. If the bite does not improve after 24 hours or if it gets worse, see your doctor immediately.
Fleas are tiny, wingless insects that feed on the blood of mammals and birds. They are prevalent in Vietnam, and they tend to hide in places where it is warm and dark, such as under furniture or in bedding.
They are most common in rural areas where dogs and cats roam free, but they can be found anywhere there is a high density of animals. Fleas can also live outside in shrubs, trees, and leaves of other plants.
The bite of a flea is often painless, but it may cause itching and irritation. Fleas can also cause an allergic reaction, which may be severe enough to require medical attention. If a flea has bitten you, you will want to treat it as soon as possible. That will help prevent infection and relieve symptoms like itching or swelling.
8. Black Flies
Black flies are small, black insects that are quite common bugs in Vietnam. These insects have huge compound eyes, large wings, and short antennae. They can be found in humid areas, near rivers, ponds, and lakes, as well as in forests and grasslands.

Some people experience a rash after being bitten. If you are allergic to black flies, it’s essential to treat the bite immediately with an antihistamine or steroid cream to prevent a severe reaction.
Midges are tiny, blood-sucking flies that can be found throughout the world including Vietnam. These little insects are small and have a brown or greyish color, often with dark markings. They are usually found near water and grassy areas, as they need trees and bushes to lay their eggs.
The bite of a midge isn’t painful but can cause itching and a burning sensation. These bites can also leave behind large welts that may take days to heal and become infected if not properly cared for. If a midge bites you, wash the area with soap and water as soon as possible to reduce irritation. You can also apply an antiseptic cream or spray to reduce pain and swelling, but this will not prevent infection if bacteria gets into the wound.
10. Vietnam Forest Scorpions

If you are stung by a carpenter bee, it may leave behind a small red bump on your skin accompanied by itchiness, swelling, and pain. In some cases, the sting may cause nausea or dizziness as well as headaches and difficulty breathing due to allergic reactions.
