Keep accurate records of each scouting assessment to compare results from different scouting trips. Scouting weekly may again be necessary to decide if numbers are declining. Recheck these fields in the fall when temperatures start to cool since rust mites can become active again once temperatures drop. Many miticides are commercially available for the treatment of mites. However, some miticides, especially the newer materials, are only effective against the tetranychid or spider mites.
Rust mites are eriophyid mites and are biologically different from spider mites.
Be sure that a given miticide specifically controls rust mites before using it. Other chemicals have not given consistent or long lasting control of this pest. Rust mites are typically not difficult to control. Be sure to scout one to two weeks after trees are treated to learn if control was successful. Another factor that reduces the success of a pesticide application to control rust mites is mixing other insecticides or fertilizers with the spray.
