Get Rid Of The Grubs In Your Lawn


Grub control is often one part of lawn care that is overlooked. Although they are out of sight, out of mind, the direct effects of their presents can be in clear sight. Understanding the lifecycle of a grub will shine light on why you need these little guys out of your lawn.


Let’s start in spring, where the adult grub worm has gorged himself for months on the root system of your soon to be struggling lawn. You can only eat the same thing for so long until you are looking for something else to eat. Now that June has arrived and the damage is done in the yard, it is now time to turn into a Japanese beetle and eat all the leaves off of your prized rose garden and your flourishing ornamental cherry trees. Grubs are the larva of Japanese beetles.


A treatment in May would have saved your lawn and reduced the amount of damage done to your plants. Lets not stop in the middle of this scenario though. After a month of snacking on your plants, its time to lay some eggs in the ground and make some baby grubs. After 2 or 3 weeks these eggs hatch and we go back to eating the lawn.


Only now your grub infested lawn is the perfect hangout for Mr. Mole and all of his friends. Moles feed on grubs and will carve tunnels across your beautiful lawn overnight. The damage to your lawn by grubs is now most noticeable in August, after the heat has took a toll on your root damaged lawn, leading to thinning and patchy unhealthy looking grass. Once cold temperatures move in in the fall, these grubs go deeper into the ground, below the frost line and out of the reach of most insecticides.

How do we fix this?


The fight is best fought when grubs are small in the late spring (May or June) or when there is a presence of Japanese beetles. Grubs are not only in the lawn but in your garden and islands as well.

For the lawn there are products like Bug B Gon, Triazacide and Bayer Advanced.


Ortho 10 lb. Bug-B-Gon Max Insect Killer for LawnsOrtho Bug-B-Gon 32 oz. Max Ready-to-Spray Lawn and Garden Insect Killer


Spectracide Triazicide 10 lb. Granules Lawn Insect Killer  Spectracide 32 fl. oz. Ready-to-Spray Triazicide Insect Killer for Lawns and Landscapes Concentrate


Bayer Advanced 10 lb. 24-Hour Grub Killer Plus Granules Bayer Advanced 1 Qt. Concentrate Complete Insect Killer for Soil and Turf


These products are available in long acting granular form that is applied with a spreader, and also in  liquid concentrates that can be applied with a garden hose. The liquids are more potent and will begin working immediately. The granular form requires water to activate the ingredient and will continue to release the active ingredient each time it gets wet.


Another, less toxic approach uses nematodes to naturally eliminate grubs. The Nema-globe Natural Grub Eliminator utilizes natural enemies of the grubs to kill them. Nematodes kill grubs without harming earthworms or other beneficial soil creatures. The time to apply nemetodes is in the spring or the fall, when the soil temperature is between 50° and 80°F. You will need to avoid all other insecticides when using nematodes since the insecticides will destroy the nematodes. Otherwise, nematodes will live for years in your soil, as long as there is a food source.

For around trees and shrubs use the Bayer Tree and Shrub or the Ortho Tree and Shrub. These products will protect your trees and shrubs from the beetles that come out after the grubs mature.


Bayer Advanced 32 oz. Concentrate Tree and Shrub Protect with Feed Ortho 16 oz. Concentrate Tree and Shrub Non-Neonic Insect Killer


Apply these products by feeding it to the roots of the tree, where it will travel up into the tree and protect it from the inside. When the beetles chew the leaf, they die. One application lasts all year. Read and follow all of the label instructions for best results.


If it has gotten so bad that moles have overrun the lawn, kill the grubs and then spray down a mole repellent, which is just castor oil and they should leave the lawn promptly.


Sweeney's 10 lb. Mole and Gopher Repellant  Tomcat 32 oz. Ready-to-Spray Mole and Gopher Liquid Repellent


Available in dry or liquid form, apply mole repellent in the area to repel the moles without harming the mole or anything else.
