Are Chigger bites contagious?

Chiggers are the common name for the larval form of the Trombiculidae mite.  Trombiculidae mites lay eggs, and the tiny larva that hatches from the eggs migrates, in large groups, onto the tops of grass and small foliage.  They wait for a person or animal to walk and jump on them.

Chiggers then seek out open areas of soft skin, tear the skin open, inject an enzyme that begins to dissolve the soft skin and feed on the liquid skin mixture.

Chiggers can feed for 2-3 days until engorged, where they will drop off.  They leave behind a straw-like appendage used to feed embedded in your skin.

How do chiggers spread?

A widespread misconception is that Chiggers burrow into your skin and life.  

This is NOT true.  

Chigger bites often take a day or two to begin itching, which helps spread this rumor. By the time you begin to notice the bites and itching, the Chiggers have generally dropped off and moved on.

The remaining appendage, combined with the torn skin and allergic reaction to the enzyme, causes the “bite” area to swell and inflate.  This intensely leads to pimple-like marks on the skin, usually in large groups.  

Chiggers not only bite humans but pretty much all animals with skin, including reptiles.  This includes your pets as well, in particular dogs.

Those that have been bitten don’t forget and generally go out of their way to never get bitten again.   This causes many to search for answers to questions like:

Do Chiggers spread?

Chigger Close Up2The short answer is: No.

Chiggers aren’t a disease, so they are contagious in the true sense of the word.   They can, however, spread from one person to another, but the risk is low.  

Do Chiggers spread on your body?

When Chiggers are crawling around on your body or clothing, searching for a good place to attach themselves, they can spread from one person to another if they are close.

Chiggers only spend a few hours looking for an exposed skin area to attach.

Know More :

Most people often shower, especially after being outdoors.  Washing with warm water and soap (as most people do) removes and kills Chiggers.  So even if you have Chiggers still on you, a shower will kill them and keep them from spreading to others.

Once Chiggers find an area of soft skin that meets their personal preference, they latch on using their jaws.   Once they latch on, they generally will either stay or die.   They will not move to another person.

Once the bites are made and the Chigger is fed, the Chigger will fall off.  Chiggers are not contagious and cannot spread further on the same person or to another person.

The bottom line is no; chiggers are not contagious.  The rash or set of bites they leave behind will not cause an infestation on another person or animal.  

Chiggers also do not transmit or spread any diseases. So, this is where you can have a sigh of relief and take these mites as they are.

In fact, other than being so uncomfortable, Chigger bites are harmless.  The only real risk is an infection.  Infection can occur when a person or animal scratches the bites, causing open wounds.  These wounds can quickly become infected and can lead to severe complications.
