With milky spore, it takes 3 to 5 years. Should I use another product in addition to get faster results?
No. Do not use any other products for grub control when using milky spore. It does take up to 2 years to see the full effect of the product but it will start working on the grubs right away. When you apply Milky Spore the existing grubs must eat the spores and digest them which in turn will multiply and spread the spores. If you kill off the existing grubs the spore will not have a way to multiply.
