Chigger bites! Help?!

Actually, you're partly right....when this post came up i was curious because i'm constantly hearing and seeing chiggers on my parents ankles, and yet my kids and i never get them. They do not live on the blood of a host, they live on the skin which they inject with a venom of sorts that makes it "drinkable"...here is the info and link

Like ticks, they bite and hang on
One of the greatest misconceptions about chiggers is that they burrow into our skin and eventually die within the tissues, thus causing the persistent itch. This widespread myth has its origin in the southern states where pests with similar names such as jigger flea or the chigoe do attack by burrowing under skin. Chiggers are not equipped to burrow, and they are much too large to enter through the pores.

If chiggers do not burrow under skin or drink blood, what are they doing that itches so much? Chiggers do bite us, much like ticks do. Chiggers attach by inserting minute specialized mouth parts into skin depressions, usually at skin pores or hair follicles.

The chigger's piercing mouth parts are short and delicate, and can penetrate only thin skin or where the skin wrinkles and folds.

That's why most chigger bites are around the ankles, the back of the knees, about the crotch, under the belt line and in the armpits. The insertion of the mouth parts is not perceptible. The bite alone is not the source of the itch.

Chiggers suck up liquefied tissue, not blood
The reason the bite itches so intensely and for such a long time is that the chigger injects saliva into its victim after attaching to the skin. This saliva contains a powerful digestive enzyme that literally dissolves the skin cells it contacts. It is this liquefied tissue, never blood, that the chigger ingests and uses for food.

A chigger usually goes unnoticed for one to three hours after it starts feeding. During this period the chigger quietly injects its digestive saliva. After a few hours your skin reacts by hardening the cells on all sides of the saliva path, eventually forming a hard, tube-like structure called a stylostome.

The stylostome walls off the corrosive saliva, but it also functions like a feeding tube for the hungry chigger. The chigger sits with its mouthparts attached to the stylostome, and like a person drinking a milk shake through a straw, it sucks up your liquefied tissue. Left undisturbed, the chigger continues alternately injecting saliva into the bite and sucking up liquid tissue.

It is the stylostome that irritates and inflames the surrounding tissue and causes the characteristic red welt and intense itch. The longer the chigger feeds, the deeper the stylostome grows, and the larger the welt will eventually become. The idea that the welt swells and eventually engulfs the feeding chiggers is also a myth. Many people have seen a small red dot inside a welt (usually under a water blister), but this is the stylostome tube and not a chigger body.

The time required for a chigger to complete its meal varies with the location of the bite, the host and the species. If undisturbed, chiggers commonly take three or four days, and sometimes longer, to eat their dinner. This is not surprising when you consider that this is the first and last meal of the young chigger's life.
