They have a warning on it while dormant spray is recommended as the best solution to spider mites.
It is not recommended that you use Bonide All Seasons Horticultural Spray oil on Red Maples as they may be damaged by the oil. Red Maples are very sensitive to oils, soaps and other insecticides and for this reason we do not make product recommendations for this type of tree. You should contact a local arborist in your area for product recommendations.
