Comprehensive Information, Resources, and Support on Scabies
The life cycle of a scabies mite starts when the female burrows into the skin and deposits eggs. Larvae hatch from the eggs within 3 to 8 days and become nymphs. Nymphs mature into adults that further deposit additional eggs. Sabies mite causes a common skin disease called scabies.
Scabies is a skin infestation caused by a tiny burrowing mite known as the Sarcoptes scabiei. The eight-legged mites burrow and lay eggs just beneath the skin. When the mite larvae work their way to the skin surface, they mature and this causes itchiness or angry rashes. Scabies mite appear creamy in color or creamy white with brown sclerotized legs and mouthparts. Scabies is contagious and can spread quickly but it is also readily treatable. The burrows or tracks appear in folds in between the fingers, in the armpits, around the waist, on the inner elbows, on the soles of the feet, etc.

Scabies is an infection spread by tiny mite known as the Sarcoptes scabiei as they reproduce on the surface of the skin by burrow into it and laying eggs. Scabies rash can spread through direct skin-to-skin contact across the whole body particularly on the skin around the hands and feet (apart from the head). Scabies cause red rashes or blisters on the skin. Scabies on foot appear like scaly patches somewhat similar to eczema. They may appear on foot fingers and on sole of the foot.
The scabies mite Sarcoptes scabiei goes through four stages in its lifecycle: egg, larva, nymph and adult. The adult female burrows into the outermost layer of skin known as stratum corneum. In this layer, the mite (an adult female) deposits two or three eggs per day by make a tunnel. She can lay upto 30 eggs in the burrow and then dies. After the eggs hatch, lavae is released. Larvae then molts into eight-legged nymphs. Small nymphs work their way to the skin surface and mature into adults in molting pouches. When male penetrates, it results in mating. After mating process, impregnated mites search for permanent burrows and again lay eggs. Mating occurs once in a lifetime in female mite.

Symptoms of scabies in animals – Animal-transmitted scabies is most commonly spread by dogs that have sarcoptic mange. This type of scabies may be spread by the mites of other domestic animals too.
