The Q&A Archives: grub control

Question: I use to have grubbs 3 years ago since i installed a sprinkler system I do not have any more should I put something down any way I am concerned with to much chemicals.

Answer: Sampling for grubs is a good first step in determining whether or not you need to treat your lawn. You can cut a square foot of turf out, pull it up and look on the soil surface and on the roots for fat, white grubs; less than six grubs per square foot can usually be masked by water and fertilizers. Populations between 10 and 15 per square foot can cause significant turf damage in September and October. Of course, populations occasionally reach 40 to 60 grubs per square foot and these levels can cause significant damage. If you find grubs you can treat your lawn with a product like Grubex or Bayer Advanced Season-Long Grub Control granules, applied according to label directions. If you don't find grubs, you won't need to treat your lawn. Good luck with your turf~!
