In 1953 US researchers tested aldrin and dieldrin on terrains with rats known to carry chiggers, at a rate of 2.25 pounds per acre (2.52 kg/ha). The aldrin and dieldrin treatment demonstrated a decrease of 75 times less chiggers on rats for dieldrin treated terrains and 25 times less chiggers on the rats when treated with aldrin.
