5 Facts About Grubs That Can Help You Identify and Prevent Lawn Damage

Grubs are pesky insects that can seriously damage your lawn if they are not caught early or controlled before the larvae hatch. These 5 facts can help you identify and prevent lawn damage this season and in the future. 

1. First and foremost, to identify something, you need to know what it looks like and many people do not know what grubs look like. They are the C-shaped larvae of a beetle and definitely large enough to see with the naked eye. They can range anywhere from 3/8″ to 2″ in length and have a grayish-white body with a brown head. In their rested state, they will usually curl into a “C”.

2. A sign that you have grubs is if you see animals (birds, raccoons, skunks, moles, etc.) digging in your lawn. These types of animals eat grubs and are likely trying to uncover them for a snack. If you see this behavior, be sure to check underneath your grass for grubs!

3. The best time of year to apply a grub control application (preventative) is between June 1st and July 15th, depending on the weather that year. To be clear, a grub control application is meant to prevent grubs from showing up next season, NOT to treat grubs that are currently present. If you have had grubs in the past, a preventative treatment is the way to go. 

4. Grubs feed on the intricate and fibrous root system of your lawn, causing serious and visible damage. Brown spots will begin to appear during the spring and fall months if you do have grubs. If grubs have already caused damage, an insecticide treatment will be the most effective in getting rid of them. 

5. Most lawns have at least a few grubs in them every year. This is not necessarily a reason to apply something to kill them. 5 or less grubs per square foot should not cause damage to your lawn. So if you see a few of these pests, don’t assume it is a problem right away. Make sure to look thoroughly before you apply any chemicals to your lawn.
