Multiple approaches are necessary for controlling Japanese beetles. Adults can be removed by handpicking and destroyed. Japanese beetle traps are available commercially or can be homemade. They may be effective at reducing adult populations.
Keep traps at least 50 feet from the crape myrtle tree or you may create more of a problem by attracting them to the area. Milky spore, Bacillus popilliae, is a disease-causing bacterium that is effective against grubs of Japanese beetles but not the adults. It is commercially available for homeowner use. Carbaryl (Sevin 50WP) or neem oil (Bonide Bon-Neem or Green Light Neem Concentrate) or cyfluthrin (Bayer Advanced Garden Power Force Multi-Insect Killer Concentrate) or permethrin (Spectracide Bug Stop Multi-Purpose Insect Control Concentrate) are labeled for use by homeowners against Japanese beetles on crape myrtle and other ornamentals. As with all pesticides, read and follow all label instructions and precautions.
