You sit on your back patio, maybe even fire up the BBQ. You may even find yourself saying to yourself, “Wow, my lawn really looks nice this year.” However, possibly unbeknownst to you, there is a covert offense trying to destroy all the hard work you put into your lawn, and it will be lingering under the surface very soon! It’s the voracious and destructive White Grub (cues dramatic music)!
If you’re reading this in Spring or early Summer, NOW may not be the time you will see grub damage. However, NOW is the time to mount your counter-offensive, or defense to squash the mighty grubs and their plans for Lawn Domination!
Know Your Enemy: What is a grub? There are many varieties of grubs. They are the larval stage of beetles. In our area, we predominately see the white grubs of Japanese Beetles, Oriental Beetles, Northern Masked Chafers, and Green June Beetles. Most people can’t distinguish which larvae they have in their lawn, but that isn’t critical in mounting a proper defense against grubs.
Know Your Enemy’s Strategy: The timing of each species slightly varies, but typically, the adult beetles emerge around the end of June to mid-July in our area. Some species like the Japanese Beetle are easily spotted feeding on plants in landscapes such as roses and various trees. However, just because you aren’t seeing Japanese Beetles during the day, doesn’t mean you don’t have beetle activity on your lawn and landscape. Some species of beetles are nocturnal, and will be most active at night. Because beetles are flying insects, you can’t prevent them from running reconnaissance missions on your property (unless you have a giant plastic dome over your lawn). There are treatments that will reduce beetle damage on your plants, but this doesn’t mean you will be safe-guarded against grubs. Beetles will come to your property to eat and mate for approximately a month during the summer and will find soft areas of lawn to lay their eggs. These eggs will hatch out in the weeks that follow, and their young larvae, will have an abundant food source, YOUR LAWN!
The Inevitable Attack: Without any pre-planned defensive, your lawn will be gobbled up by the larvae. They feed beneath the surface, causing large areas of lawn to die, as they eat the root system right out from underneath. Most times, lawn owners don’t realize what is wrong with their lawn until they see it not recovering in the fall like neighboring lawns. A closer look will reveal the hidden army below. Your only chance to stop this attack at this late-summer or early-fall time frame would be to apply a Corrective Grub Control, such as Dylox, and then renovate your lawn. These materials, and obviously the cost of seeding will cost a great amount more than doing a Preventative Grub Control Treatment in the late-spring/early-summer.
A Turning Point in the War: If you had done your counter-intelligence in Spring, you would have know that was the time to apply Preventative Grub Control. There is an array of different materials, but the industry-preferred materials for years have been Merit (imadicloprid) or Acelepryn (chlorantraniliprole). Applying these materials in late spring through the end of July will be a defense that is no match for grubs. The material typically gets watered-in after application by Mother Nature. There it lays in the first couple inches of soil under your lawn, like a sniper in the grass waiting for intruders. When the young grubs hatch and go looking for food, it’s “Curtains” for their plans of lawn domination.
Joining the War on Grubs: We want YOU to join us in our fight to keep lawns beautiful! You would be wise to enlist a lawn program that controls grubs preventatively. Recruit a trusted, local lawn care company to perform this application for you. Some providers, like Tomlinson Bomberger, guarantee this service. Together, we can beat these lawn terrorists and keep our lawns safe and beautiful!
