Insects – they buzz, they crawl, and they can be a major nuisance. But did you know that some of these tiny creatures can make your body their home? While the idea of bugs living inside you might sound like something out of a horror movie, the reality is that certain insects and parasites have figured out how to survive in and on the human body. Don’t panic, though! Most of these critters are avoidable, and we can spot the signs early before they cause any real harm.
Let’s take a closer look at six insects and parasites that can live inside you, how to detect them, and most importantly, what you can do to prevent them from making themselves too comfortable.
1. Head Lice (Pediculus humanus capitis)
Head lice are tiny, blood-sucking parasites that love to live in your hair, especially on your scalp. About the size of a sesame seed, they feed on your blood, causing irritation and itching. These little critters are often spread through close contact, like sharing hats or coming into direct head-to-head contact with someone who’s already infected.
How to Detect Them:
- Itching: An intense itch on your scalp is usually your first sign. It’s caused by an allergic reaction to the lice bites.
- Visible Lice: If you look closely, you might see the tiny lice moving around, especially behind the ears or at the back of your neck.
- Nits: These are the eggs of the lice, and they look like small, shiny grains stuck to your hair shafts.
Prevention:
- Avoid close contact with others who may have lice.
- Regularly check your hair and your children’s scalps for any signs of lice.
- Wash clothing and bedding in hot water to kill any lice or nits that may be lurking.
2. Earwigs (Forficula auricularia)
Earwigs are often associated with their creepy name, but they are not usually dangerous. These nocturnal insects are most known for their pincers, which they use for defense or to capture prey. Though rare, earwigs can sometimes make their way into human ears while people sleep, seeking dark, moist places to hide.
How to Detect Them:
- Discomfort in the Ear: You may feel an unusual sensation or discomfort in your ear, especially if an earwig has crawled in.
- Visible Earwig: If you inspect the ear canal, you might spot the earwig itself, especially if it has lodged itself deeper in the ear.
- Buzzing or Itching: Earwigs inside the ear can cause an irritating buzzing or itching sensation as they move around.
Prevention:
- Sleep with your ears covered or use earplugs if you’re in an area with a lot of earwigs.
- Keep windows and doors tightly sealed to prevent earwigs from getting inside.
- If you suspect an earwig in your ear, visit a healthcare provider to have it safely removed.
3. Pubic Lice (Pthirus pubis)
Pubic lice, also known as “crabs” due to their crab-like shape, are small parasites that live in coarse hair, like around the groin area. These lice are most often spread through sexual contact, but they can also be transferred through shared clothing or bedding.
How to Detect Them:
- Itching: Severe itching in the pubic area is caused by lice bites.
- Visible Lice & Nits: You may spot tiny, crab-shaped lice in the pubic region or find eggs (nits) stuck to the hair.
- Dark Spots: Pubic lice bites can cause dark spots on the skin where they’ve fed.
Prevention:
- Avoid close, sexual contact with anyone who may have pubic lice.
- Wash clothing and bedding at high temperatures to kill lice or nits.
- Special shampoos and treatments are available to eliminate pubic lice if you do end up with them.

4. Botflies (Dermatobia hominis)
Botflies are tropical parasites that are, frankly, a bit terrifying. They don’t directly lay eggs on your skin. Instead, they use mosquitoes as “delivery services” to implant their larvae under your skin. Once inside, the larvae grow, causing swelling and discomfort as they mature.
How to Detect Them:
- Painless Bumps: A bump or swelling under your skin is often the first sign, along with a small hole where the larvae breathe.
- Itchiness & Pain: As the larvae grow, they can cause redness, itchiness, and even pain as they burrow deeper into your skin.
- Movement Under the Skin: It’s unsettling, but you might actually feel the larvae moving under your skin.
Prevention:
- If you’re traveling to tropical regions, wear protective clothing to minimize exposure.
- Use insect repellent to keep mosquitoes at bay.
- If you suspect you have a botfly larvae under your skin, see a doctor immediately for safe removal.
5. Tapeworms (Taenia solium)
While not technically an insect, tapeworms definitely deserve a mention. These long, flat parasites can grow up to several feet inside your intestines. You typically get them by consuming undercooked or contaminated meat, especially pork or beef. Once they’re inside, they attach to the walls of your intestines and can cause all sorts of digestive issues.
How to Detect Them:
- Abdominal Pain: Stomach discomfort or pain is a common sign of a tapeworm infection.
- Weight Loss: Despite eating regularly, you may start to lose weight because the tapeworm is stealing your nutrients.
- Visible Segments: You might notice segments of the tapeworm in your stool. These look like small, white pieces that resemble grains of rice.
Prevention:
- Avoid eating undercooked meat, particularly pork and beef, which can carry tapeworm larvae.
- Always wash your hands thoroughly before eating and after handling raw meat.
If you suspect a tapeworm infection, see a doctor for treatment. Medication will kill the parasite and get you feeling better in no time!
6. Scabies (Sarcoptes scabiei)
What Are They?
Scabies is caused by a tiny mite called Sarcoptes scabiei, which burrows into your skin to lay eggs, causing intense itching and irritation. Scabies is highly contagious and spreads through prolonged skin-to-skin contact or sharing infested bedding or clothing.
How to Detect Them:
- Itching: Severe itching, especially at night, is the hallmark of a scabies infestation.
- Rashes or Sores: You’ll notice red, pimple-like bumps or sores on your skin, particularly in the folds of your body (elbows, knees, armpits, and genital areas).
- Burrows: Tiny, thread-like tunnels may appear in the skin where the mites have burrowed.
Prevention:
-
- Avoid close, prolonged contact with anyone who has scabies.
- Wash all clothing, bedding, and towels in hot water to kill the mites.
- Scabies is treatable with prescription creams or oral medications, so see a doctor for treatment if you suspect an infestation.
In conclusion, Stay Vigilant and Clean! While the thought of insects and parasites living inside your body might make you cringe, the good news is that most of these pests are avoidable with the right precautions. Regular hygiene, vigilance, and taking extra care when traveling can help you avoid these unwanted guests.
By practicing good hygiene, regularly checking for signs of infestations, and seeking medical attention if necessary, you can keep your body free of these pesky critters. Remember, your body is your home, and it should only be filled with you!
