Over the last few weeks I’ve slowly noticed some brown spots appearing in lawns adjacent to my property. I am typically proactive when it comes to maintaining my lawn and I like to make sure weeds are in check and if there is a cooler period in the summer, I will take the opportunity to apply more nitrogen, (fertilizer) to insure a nice, thick green lawn. I kept thinking to myself, I am sure glad I do not have grubs in my lawn.
Well, all of that changed in the last couple of weeks.
I began noticing a few, small brown spots. I wrote it off as the lawn needing more water so I watered a little more the past couple of weeks. Last night as I mowed over these areas, I could see that not only were these areas brown, but they had spread and instead of a few, there were several brown spots. Meanwhile my neighbor’s lawns had particularly brown, dead grass and even more brown spots in their yard. If you dig up these areas, you will see those disgusting white wormy creatures.
The point here is that it does not take much for grubs to appear and spread. The ideal conditions of heat and humidity bring help accelerate the process. Normally, I see grub damage like this in the middle of August. With the higher temperatures and humidity in the midwest, we are about 2-3 weeks ahead of schedule. Normally in May I add some grub killer to areas where grubs have appeared in past years. I did apply grub killer to these areas and have not seen any grubs. Unfortunately, my back yard, where I had never had grubs before was the area that had the most grubs.
The good news is that grub killer is available at your local hardware store or Home Depot. Don’t mess around with an insecticide as some articles suggest. Go for the grub killer and address the bugs directly before more damage occurs. So if you are seeing some dry areas in your yard, make sure you get to the root cause. Most of the time it’s not about watering more, it’s about dealing with grub activity. If your neighboors have grubs, there is a good chance your lawn will be a prime canddidate for grubs.
