During the summer, a 46-year-old French woman presented with pruriginous dermatitis of the scalp. She reported feeling as if “small beasts ” were falling from her scalp, especially in the evenings, annoying her during her work and sleep. Antilice lotions were ineffective, as was oral ivermectin treatment at 200 μg/kg. Many bites and scratches were visible on her back (Figure 1). The dermatologist discovered insects less than 0.04 of an inch long and sent them for identification to the Parasitology Service of the University Hospital of Tours.
