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 :D

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 ).

Merit is a great product to prevent grubs, spring treatment to control fall feeders is how merit works

Mach 2, well Ive never had good luck with it cause certain species of grubs are not effected by it. And its alot cheaper, IMO you get what you pay for.

Many people think they need to control grubs in spring, but they do very little feeding in the spring, ( yes their present ) so a treatment is most likey a wasted treatment and unwarrented.

Dylox is a great product to apply in fall when their feeding, quick knock down but dosent last very long
