Allen, Your suggestion about an acaricide meaning only refering to acarine
disease should be modified a mite (couldn't resist, excuse me).
An acaricide is a pesticide that is used to kill mites of all
kinds.
Ths mites fall under the scientific class name Acari, therefore acaricide
literally means "mite killer".
Another example, insecticide - a material that kills insects
I know this was mitey picky of me ...
