Sarcoptic Mange is caused by a tiny mite called "Sarcoptes scabiei," that burrows under the skin to feed on the blood of the squirrel. It causes severe itching, a rash, crust formation on the skin and hair loss. The picture on the left shows an Eastern Grey with mange on it's lower back. Notice the red, crusty area in the center of each patch of missing hair. The irritation, rash and crusting of the skin is what differentiates mange from Dermatophytosis. This squirrel would do well by treating it with a small quantity of Ivermectin Paste spread on a Nut Meat. We give approximately 1/2 to 1 drop of Ivermectin 1.87% once a week for 3 weeks to make sure that all active mites and all newly hatched mites are killed.
