Chiggers and scabies are both common skin conditions that can cause discomfort and itching, but they are caused by different organisms and have distinct characteristics.
Chiggers, also known as harvest mites, are tiny red mites that are found in grassy and wooded areas. They bite humans and animals to feed on their skin cells, causing intense itching and red welts. Scabies, on the other hand, is caused by a microscopic mite called Sarcoptes scabiei. This mite burrows into the skin, laying eggs and causing a pimple-like rash and intense itching, especially at night.
It is important to understand the key differences between chiggers and scabies in order to properly diagnose and treat these conditions. By recognizing the unique characteristics of each skin condition, individuals can better manage their symptoms and seek appropriate medical care.
What Are Chiggers?
Chiggers are tiny parasitic larvae of mites that belong to the Trombiculidae family. These larvae are red in color and are commonly found in grassy areas, forests, and gardens. Chiggers feed on skin cells by attaching themselves to the host’s skin, causing intense itching and irritation. Unlike scabies, chiggers do not burrow into the skin but instead inject enzymes that break down skin cells, feeding on the liquefied tissues.
| Chiggers | Scabies |
|---|---|
| Parasitic larvae of mites | Parasitic mites |
| Feed on skin cells | Burrow into the skin |
| Found in grassy areas, forests, and gardens | Spread through close contact with an infected person |
What Is Scabies?
Scabies is a highly contagious skin infestation caused by the microscopic mite Sarcoptes scabiei. These mites burrow into the skin, where they lay eggs and cause intense itching and irritation.
The main symptom of scabies is a red, bumpy rash that often appears in the folds of the skin, such as between fingers, wrists, elbows, and buttocks. The itching associated with scabies is typically worse at night and can be severe.
Transmission of Scabies
Scabies is usually spread through prolonged skin-to-skin contact with an infected person. It can also be transmitted through infested bedding, towels, and clothing. Scabies can affect people of all ages and socioeconomic backgrounds.

Transmission of Chiggers
Chiggers are mites that are typically found in grassy areas, forests, and other outdoor environments. They are most active in the spring and summer months. Chiggers can attach themselves to humans when they come into contact with tall grass or vegetation where the mites are present. Once attached, chiggers inject enzymes into the skin that break down skin cells, allowing them to feed on the skin tissue. This feeding process can cause intense itching and irritation.
Transmission of Scabies
Scabies is a highly contagious skin infestation caused by the Sarcoptes scabiei mite. The mites burrow into the skin, where they lay eggs and cause intense itching and discomfort.
The most common method of transmission is direct skin-to-skin contact with an infected individual. This can occur during activities such as close personal contact, sexual contact, or sharing bedding or clothing.
In some cases, scabies can also be spread through indirect contact with contaminated objects such as furniture, towels, or bedding. The mites can survive away from the human body for up to 72 hours, so it is important to properly clean and disinfect any potentially contaminated items.
Symptoms of Chigger Bites
Chigger bites typically appear as red, raised bumps on the skin.
The bites can cause intense itching, often worse at night.
Blisters or hives may develop around the bites.
Severe itching and discomfort are common symptoms of chigger bites.
In some cases, a rash or welts may form on the skin.
Symptoms of Scabies Infestation
The most common symptom of scabies is intense itching, especially at night. This itching is caused by the body’s allergic reaction to the mites and their waste products.
Other symptoms of scabies include a rash with small red bumps or blisters, usually appearing between the fingers, on the wrists, elbows, armpits, waist, thighs, genital area, or buttocks.
In severe cases, scabies can lead to a crusted, thickened skin that can be easily mistaken for eczema or psoriasis.
If left untreated, scabies can spread rapidly through close physical contact with others, making prompt diagnosis and treatment essential.
Treatment Options for Chigger Bites
If you suspect you have been bitten by chiggers, there are several treatment options you can try to relieve the itching and discomfort:
1. Wash the affected area with soap and water: This can help remove any remaining chiggers on the skin and reduce the risk of infection.
2. Apply calamine lotion or hydrocortisone cream: These over-the-counter products can help reduce itching and inflammation caused by chigger bites.
3. Take an oral antihistamine: This can help alleviate itching and reduce allergic reactions to chigger bites.
4. Avoid scratching: Scratching can lead to skin infections, so try to resist the urge to scratch the affected area.
5. Keep the affected area clean and dry: This can help prevent further irritation and allow the bites to heal more quickly.
6. If the itching persists or if you develop a rash, consult a healthcare provider: They may prescribe a stronger topical medication or other treatment options to help alleviate your symptoms.
Treatment Options for Scabies Infestation
There are several treatment options available for scabies infestation, depending on the severity of the condition. It is important to consult a healthcare professional for a proper diagnosis and treatment plan. Here are some common treatment options:
1. Topical Medications
- Permethrin cream: This medication is the most common treatment for scabies. It is applied to the entire body from the neck down and left on for 8-14 hours before washing off.
- Ivermectin lotion: This prescription medication is used for those who cannot tolerate permethrin cream or when the infestation is resistant to other treatments.
2. Oral Medications
- Ivermectin pills: In severe cases of scabies, oral ivermectin may be prescribed to kill the mites. It is usually taken as a single dose.
It is important to follow the treatment plan prescribed by your healthcare provider and to avoid re-infestation by washing bedding, clothing, and personal items in hot water and drying on high heat. Close contacts may also need to be treated to prevent the spread of scabies.
Prevention Tips for Avoiding Chigger Bites
- Avoid walking through tall grass and weeds where chiggers are commonly found.
- Wear long sleeves, pants, and closed-toe shoes when spending time in areas with chiggers.
- Apply insect repellent containing DEET to exposed skin to repel chiggers.
- Shower immediately after outdoor activities to wash off any chiggers that may be on your skin.
- Wash and dry clothes on high heat to kill any chiggers that may have attached to your clothing.
Prevention Tips for Avoiding Scabies Infestation
1. Avoid close contact with individuals who have scabies.
2. Wash bedding, towels, and clothes of an infected person in hot water and dry on high heat.
3. Keep personal items, such as clothing, towels, and bedding, separate if someone in the household is infected.
Personal Hygiene
4. Maintain good personal hygiene by bathing regularly.
5. Trim fingernails to reduce the chance of scratching and spreading the mites.
6. Avoid sharing personal items, such as clothing, towels, or bedding, to prevent the transmission of scabies.
