Why Are Lawn Grubs Such a Nuisance and How to Get Rid of Them

how to get rid of lawn grubsLawn grubs are pests that can damage your lawn especially if they are in large quantities. When they are in small numbers, the damage they do is masked by the growth of your grass. When your grass is not growing very much, or when they have large numbers, the damage that they do is much more substantial and can become permanent as they kill your grass.


The way that a grub worm subsists by eating the roots out on your plants. They do most of their damage in the late spring and early summer before they molt and turned into adults. White lawn grubs are the larva of beetles, moths and a few other types of insects. Because they eat the roots out on your grass, you can know that you have them if there is a yellow spot in your lawn where the grass tears out very easily. You also know if you have them, if all of your sod dies except tiny little pieces around your lawn.

In order to prevent your sod from dying and having to replace your lawn, it is a good idea to find out if you have an infestation.  If you do, use grub control to get rid of it. The easiest way to know if you’re going to have a major problem, is to a sample the soil and see how many grubs you have in it. Usually if you have four or five grub worms together, this means you have an infestation. You should use grub control to treat your lawn as soon as possible. For those of you who prefer to control grubs organically, you should use a pair of aerator shoes with 2 inch spikes on the bottom of them.


This method of organic grub control involves you walking over your lawn a half a dozen times with these spikes on your feet. This should allow you to kill enough of the grubs that they will stop damaging your lawn faster than it can repair itself. Otherwise, the poison seems to work pretty good. Depending on the time of year that you put the poison down, you may have to put it down twice, three weeks apart, to make sure that you kill the grubs that might be in different stages of their life cycles. Once you have had a lot of grubs in lawn, it is a good idea to check next year to see if they come back. If they do, treat them to get rid of them.
