Hello!
We are about to lay 5000 sq feet of sod, replacing an old lawn that was destroyed by grubs. We are going to amend the soil with a double mix and compost. Should we spread cyfluthrin granules prior to amending the soil and replacing the sod? Will we have to treat the new lawn as well? Thank you for your help.
First and foremost, I urge you to get a good PH read on the soil that will be underneath the new dirt you lay out. Proper PH is paramount to keeping a good lawn and many people ignore this vital component. You can read more on soil ph here:
Next, once the sod is laid, get into a good fertilizing program as outlined here:
Lastly, the grubs… Grub control is something that most any homeowner will have to deal with at some point as explained in our GRUB CONTROL ARTICLE. The good news is that you can control them with very little effort if the problem is maintained. This means taking the time to treat before they’re well established. Based on your message, it sounds like you’ve been dealing with them in the past. If this is true, getting a good liquid and granule application made to the underlying soil would be wise. I would do the following.
1) Apply the MERIT GRANULES to the soil.
2) Followup with a liquid treatment of the CYONARA RTS
These two products will take care of anything in the old or new soil and should provide protection for the rest of this year. Next year you should only have to apply the Merit once in the spring and if you maintain this grub treatment program, you should be able to stay grub free indefinitely. Good luck!

Can I treat the soil with grub killer before I lay new sod?
Tech Support says
Rubin,
If you review our grub control article, you’ll see we a product listed called Prothor. Its very gentle and can be applied anytime. I use it once a year for my Zoysia and it keeps my turf grub free for the whole season. I recommend using it in the spring (here in GA I get mine applied late Feb, no later than half way through March). Once in the ground, any grass or shrubs will pick it up over the coming months and in turn, the active will kill any insect that tries to eat the grass or its roots.
Prothor can be applied now, just before you apply the sod, after you apply the sod, etc. Its by far your best long term control for grubs and will outperform any granule.
