Pesticides formulated to kill mites and ticks, used on crops, stored products, livestock and in beehives against the Varroa mite. Common examples include amitraz, bromopropylate and fluvalinate. Because they are applied directly to food-producing plants and animals, residues can reach consumers through produce, honey, milk and meat, so regulators set maximum limits and beekeepers observe withdrawal disciplines. Resistance is a growing headache, driving integrated pest management that rotates chemical classes with biological and cultural controls. Acaricides sit at the intersection of crop protection, animal health and residue chemistry.
