Is Malathion 57% the best for Japanese beetles?


Malathion 57% is labeled for Japanese Beetles and should do a great job for you when used as directed on the product label.  Malathion 57% is typically meant for treating large areas or crop land.  We would recommend Talstar P.  It is a insecticide that is labeled for lawn and ornamentals and is safe for plants, bushes, shrubs and trees.  Talstar will provide a 30 day residual on the plants that you spray and should provide relief against the Japanese beetles whereas the Malathion will only kill the ones that it makes contact with during application. Here is a great article on treating this pest for more information.
