Managing Japanese Beetles and Spider Mites Organically

Long-Term Beetle Control with Milky Spore; Mites with Soap

Japanese beetles: apply milky spore to soil for grub control (takes years). Spray adults with neem oil. Spider mites: blast with water or spray insecticidal soap. Keep plants hydrated—drought stresses invite mites. Avoid broad-spectrum insecticides that kill beneficials.
