Lawn Grub Worms ,How to Get Rid of Them


UPDATE April 2008– if you are finding grubs in your lawn this Spring click here. But if you are reading this in summer or fall, then stay here and read the rest… free lawn care advice follows!… (and yes, I’ll tell you if BEER works on grubs too)
UPDATE JUNE 2009– see the video below for more info on a special grub worm killer that will work for many of you who have trouble watering your lawns in the hot summer months.
Lawn Grub Worms and How to Prevent or Get Rid of ThemHere in the Midwest and Chicago area (and many other parts of the USA), the dreaded grub worm (larvae of the June bug) is preparing for it’s annual late Summer feast. And, since you have been a regular reader of this blog, you certainly are a prime candidate because you’ve followed all of my advice to the letter, and your lawn is perfectly healthy and green; ripe for an all-you-can-eat frenzy.
With White Grubs, timing is everything
If you are reading this article in September or October, and seeing brown spots in your well-irrigated lawn, chances are that grubs are the culprit. All you have to do is lift up the outer edges of the dead spots and look for the “little shrimp” feeding underneath. If you find them, go get some Sevin or other granular insecticide and spread it across the affected areas and water it in. This will kill the grubs and stop them in their tracks.
But if you are reading this article and it is around the timeframe of June or July, then you should put down a preventative insecticide in your lawn to STOP the grubs. I have noticed grub worm populations rising in the last couple of years. 2007 was the worst year I have seen in decades of green industry involvement, and 2008 is poised to be the same or worse.
When buying a grub worm preventative, you should look for one containing a long lasting grub worm preventative! The product Merit is the industry standard grub preventing product. It must be watered in to the soil to be effective. Scott’s Grub-X contains Merit and is a good product for the DIYer. But there is an inherint problem with Scott’s grub X and that is that it contains high nitrogen fertilizer mixed with it and this is the worst thing you can put on your lawn in the hot summer! Nitrogen PUSHES overgrowth… not a good thing in hotter months! (see vid below)
There are also organic grub preventative products, such as milky spore, that do have some effect on grubs, but they must be applied several times over the course of the season. Plan to spend a few bucks to go organic in this particular area of lawn care. I respect you if you do!
