Can I also use Merit or Dylox with this?
I have a new lawn only two years old, but already see the grubs and the beetles. I need the best solution, please advise.
For Milky Spore Powder to work, live grubs have to ingest it and Dylox 6.2 Granules and Merit Granules will kill them. For long term treatments, we would recommend using Milky Spore Powder. This is a slower acting product, but it will last about 15-20 years in the soil after one application.
With Merit Granules, it is most effective when applied prior to, or just after, egg lay. In most cases, adult emergence occurs in early summer, often after significant rainfall or irrigation, followed by mating and egg laying. This usually continues for four to six weeks. Under normal circumstances, Merit will provide residual white grub control for four months or longer in turf.
