From the Greek akares, short, small, tiny. Fear of mites or insect bites. Insects of our natural environment as wasps, mosquitoes or horseflies are relatively preventable, not so mites, our tenants by millions, but we can take some measures against them such as daily ventilation of the rooms, wash often linens, plush dolls, rugs, tapestries or prevent domestic animals. An acaricide proper is the tannic acid.
