Holy Moths Batman!

What are these Moths? For Pete’s sake, Pete, they’re everywhere.

Well, it’s not quite the invasion of Mothra, giant moth creature who flew over Japan in the 1960’s, but it seems almost as bad right now. Out of nowhere, all of a sudden there are literally thousands upon thousands of little white moths flying around.

Walk through your grass, mow your lawn or pick some vegetables and there they are, fluttering about like mad. Fortunately, they’re so small, they’re easily brushed aside. But still, so many, so late in the season. What’s going on?

These moths are Sod Webworm Moths, also known as White Grass Moths or Lawn Moths. There not big, and when they sit with their wings folded back, they look almost like large grains of rice.

They have appeared in massive numbers recently for any number of reasons including just the right weather conditions. We had very few miller moths this spring, so perhaps we’re paying the price for that now. I walked by a building today with literally tens of thousands of these moths on the walls and on the sidewalk.

Okay, so what else can we expect from these, Pete? Well, they’re just annoying to you, but are far worse to your lawn.  

These moths are the adult stage of the sod webworm. Sod webworms live under your lawn and eat away at the roots of your grass. Not good! This time of year, the moths are flying around and laying eggs for their young. When these eggs hatch, the hungry kids go underground and start chewing away. If you have a healthy, well fertilized yard, it may be able to fend off these attackers on its own. However, you may need to put down a grub killer also. Go to your local Ace Hardware store and ask the helpful hardware folks for GrubEx from Scotts or Grub Control from Bayer. Both are granules that you apply with a spreader and water in. It’s not too late to apply this right now, and doing so along with your winterizer fertilizer will give your lawn a good defense from the bazillions of little grub kids under your grass.

If you have small brown dead patches, they can start as small as a golf ball, that means you may have grubs. Pull up a slice of lawn and look under it to see if they’re hiding down there at your all-you-can-eat grass root buffet. If so, definitely apply grub control and water in well or those dead spots will spread quickly. If you normally wait until October to apply winterizer, you may want to move that up and apply it now. Healthy, well-fertilized grass will stand a much better chance at regenerating the roots that those grub kids may eat.

So, take it from me, Pete Moss, don’t be that mean old guy who yells, “Hey kids, get off my lawn”, be the guy who says, “Hey grubs, get out from under my lawn!”
