Acaricides are pesticides that kill members of the arachnid subclass Acari, which includes ticks and mites. Acaricides are used both in medicine and agriculture, although the desired selective toxicity differs between the two fields.


More specific words are sometimes used, depending upon the targeted group:

  • "Ixodicides" are substances that kill ticks.[1]
  • "Miticides" are substances that kill mites.
  • The term scabicide is more narrow, and refers to agents specifically targeting Sarcoptes.
  • The term "arachnicide" is more general, and refers to agents that target arachnids. This term is used much more rarely, but occasionally appears in informal writing.

As a practical matter, mites are a paraphyletic grouping, and mites and ticks are usually treated as a single group.


Examples include:

Acaricides are also being used in attempts to stop rhinoceros poaching. Holes are drilled into the horn of a sedated rhino and acaricide is pumped in and pressurized. Should the horn be consumed by humans as in traditional Chinese medicine, it is expected to cause nausea, stomach-ache and diarrhea, or convulsions, depending on the quantity, but not fatalities. Signs posted at wildlife refuges that the rhinos therein have been treated are thus expected to deter poaching. The original idea grew out of research into using the horn as a reservoir for one-time tick treatments; the acaricide is selected to be safe for the rhino, oxpeckers, vultures, and other animals in the preserve's ecosystem.
