    Posted this over in the general landscaping forum, but thought I'd get some of your opinions as well, thanks guys.
    I have had several customers in the past few weeks, whos lawns have suffered from grub damage. I'm assuming it happened last summer or fall (they weren't lawn customers at that time). Now they want me to take care of the grubs, and make their lawn come back. I've searched the boards and asked around and it is my understanding dylox, does not affect new seed and it should be safe to use in combination, do you guys agree?? Secondly, is now really the right time to treat for grubs?? Sodding is out of the question, and the lawns are both in the condition that allows them to easily be pulled up and leave nothing but dirt exposed, so I would probobly put down some add some fresh top soil, and then seed.

    Overall I'm curious if 1) Grub control and seed can be used at the same time?
    2) Would grub control have an effect right now?

    Thanks in advance? I'm pretty good with most lawn treatments, but grubs always leaves me with a few questions.

    It is very rare for Spring grubs to be damaging enough to warrent treatment. The generation that feeds in Late Summer/Fall are the ones to worry about. Areas could be reseeded now, but Dylox would do no good. An application of Merit In Summertime will take care of those grubs later on in the year.

    To answer your question on Dylox affecting seedlings...No, it doesn't affect them.

    Hope that helps, & make sure you're licensed if applying for hire:)

    I would do the job in May/june and use a merit combo. The early generation of white grubs rarely shows any damage do to the roots being able to out grow the damage.

    I am in the same position this year and although I haven't had the experience of it in the past a local repitable chem guy told me that the spring grubs won't do much and a heavy dose of merrit around the first week of july would do the trick however I don't think I'll be reseeding until the fall because seed in the spring just won't have very good results or last through the summer.

    See, here in my area, I have a whole different experience, all together. I do treat in the spring...especially if reseeding is done in the fall without a grub treatment, or if I do it in the spring. The majority of the damage is done by the end of fall...there is absolutely no question about that. But sometimes, when the grubs resurface after overwintering, as they come up with a veracious appetite, they can do a significant amount of additional damage - and fast. There is nothing worse than doing a grub damage repair, only to have the grass come up nicely but be surrounded by a ring area that looks like it it come in, when in fact, what happened was it was there, and is now gone. One benefit of having to treat at this time though, is that only the outer perimeter of the damage (and into the good turf, of course) needs to be treated. Now, if this repair is to begin late enough in the spring, or early summer, then there is really no need.
