Characters:
01.
Sarcoptic Mange Mites are tiny arachnids (cousins of ticks and spiders) that are
parasites of mammals. They cause the disease known as
"mange" or "scabies."
02.
These mites are tiny, only 1/64 of an inch long. They are pearly
white in color and oval-shaped. They have spines on their bodies and legs. They
have no eyes.
03.
Sarcoptic Mange Mites spend their entire life on their hosts. The host is the animal that the mite
lives on.
04.
Sarcoptic Mange Mites are parasites of squirrels, rabbits,
foxes, dogs, humans, and many other mammals.
05.
Scarcoptic Mange Mites use small suckers on their legs to hold
onto their hosts.
06.
After mating, female mites burrow into the skin of the host.
They use their jaws and front legs to cut the skin. They mites tunnel in the
top layer of the skin only.
07.
Inside the burrow, the female will lay eggs. She lays two or
three eggs each day, for up to two months.
08.
Mite larvae hatch from the eggs in three or four
days. They immediately crawl out of the burrow onto the surface of the skin.
The will stay here, using the host's hair as shelter. Both larvae and adult mites eat skin cells from their hosts.
09.
Once a larva has eaten enough, it will molt (shed its skin). After it molts twice,
it has become an adult.
10.
Adult mange mites mate on the surface of the host's skin.
11.
The disease caused by these mites, called
"mange" or "scabies," starts with a substance from the
mites' bodies. This substance causes an allergic reaction in the host's skin, and it
becomes very itchy.
12.
When the host scratches itself, it makes wounds that
become infected by bacteria. The scratching also causes hair to
fall out and animals with mange will often have bald patches.
