Japanese Beetles

Japanese Beetles have arrived in the Twin Cities.  For quick knock down use Spinosad or Carbaryl.  For longer term effect try deltamethrin or bifenthrin.

To kill grubs apply a good grub killer to your lawn between July 15th and Aug 1st.  For best results dethatch lawn first then water grub killer in after application.
