Pest Alert: Grub Control


Keeping your lawn healthy and clean is a hassle enough but year after year pests can make it even more difficult. If you've noticed  thinning grass and/or patches in your lawn chances are its time to check for grubs. The easiest way to check for grubs is to simply dig up some soil of about 2 inches deep and examine it. 

Grubs are easily identifiable and it will be obvious right away if this is the cause of your thinning grass. These pests vary in size but are more commonly about 1/4" to 1-1/2" in length. In the mid-west, common grub species include the Japanese beetle, masked chafers, European chafer, Asiatic garden beetle, and the Oriental beetle. These belong to the white grub grouping and are typically white and C-shaped. When warm weather arrives these grubs begin moving closer to the surface and feeding on grass roots. Therefore the ideal time to check for grubs is during spring when the weather begins to warm, but they can be found at other times of year as well. Now that you've identified whether or not the problem is grubs we will talk about how to prevent and get rid of them.  


Thankfully there are plenty of pesticides that will fight off these grubs that are destroying your lawn, but picking the correct product is very important. The two main grub control chemicals include carbaryl and trichlorfon. These chemicals kill all life stages of grubs and should be applied in the spring through late summer as they will be more effective.  Once the grub control is applied it is still important that you began a preventative plan for the following year. Preventative grub control is more effective and efficient, but in order for it to properly prevent grubs, it must be applied in June or July. Preventative care is only needed if you have had a history of grubs in your lawn otherwise it's not necessary after a year or two of treatment. With both grub control and preventive care, you must water your lawn right after applying the pesticide to ensure the highest results. No matter what chemical you use, be sure to read the label completely to make sure you're applying it in a way that's safe for you and your pets, and also to do the least harm to beneficial insects such as pollinators.
