Any advise on how to treat grubs if they have had grubs before.
when to treat and what mix (with fertilizer). Customer is asking so she can spread her self. What if they have'nt had grubs and want to prevent them. Thanks for the help
The best route is a preventive treatment of either Merit or Mach II
in June or July. Both products are available with or without fertilizer. If you listen to the radio ads, they will have you treating these in April ( way too early ).
