I know I have a white grub problem. I had some landscape work done last fall and my grass was loaded with them. Especially under areas where the grass had just died. I thought it was the lack of water and had been watering trying to save the grass but that was a waste. There were thousands of grubs in there and I haven’t treated. When should I spray? Spring, like April? I want to get them under control early so the grass doesn’t die again.
Actually you should have started treating last fall when you first discovered the problem. White grubs are active year round as our GRUB CONTROL ARTICLE explains. And in the winter – especially mild winters – they’ll be extra active and right up top so they’re easy to kill. In fact, now is the best time to get them.
I suggest you get some COMPLETE LAWN GRANULES now and apply them over all your turf. Next spray some CYONARA RTS. Treat again in April the same way and by summer they will be gone.
Come next fall, you can reduce the treatments to just granules, no spray. Treating ever 3 months with nothing but the granules will keep them in check and they shouldn’t return. At that time you can change over to the MERIT GRANULES. These last 3-6 months and generally only need to be applied twice a year.
