Tulsa Lawn Care Critical Alert – Armyworm Invasion


Tulsa and surrounding areas (all of our service areas) are currently experiencing a sudden explosion of armyworms.  This invasion is close to the magnitude of the devastating (to lawns) invasion of 2002.


Armyworms can eat an entire lawn overnight and leave you with a dead, brown lawn.

Why do we have them?  There isn't  really any way to know for sure, but the past mild winter may have contributed to the problem, since armyworms usually don’t survive freezing conditions.

It is critical that you inspect your lawn for any indication of army worms.  We have seen them in all stages of growth – adults, babies, and moths.


If you have them, they will be visible and look like little caterpillars if they are in that stage.


To All of Our Full Program Lawn Care Customers:


Your full program with GreenGrass includes free treatment for lawn damaging insects.

However, we are simply inundated.


If you see armyworms, call us and we will put you on the list.  We are getting to as many lawns per day as possible and are currently working full force on this issue.


We strongly suggest that if you see them and we unable to get out to your lawn  quickly, that you go ahead and buy something at the home and garden store and spray them yourself.


Most lawn and garden centers are knowledgeable and can advise you on what product to buy.


Following are some product recommendations from OSU extension fact sheets:


  • Ortho Bug-Be-Gon Max Lawn and Garden Insect Killer Concentrate (ingredient bifenthrin)
  •  Bayer Advanced Power Force Multi-Insect Killer Concentrate
    (ingredient cyfluthrin)
  • Enforcer BugMax Insect Killer Concentrate (ingredient deltamethrin)


Most of these products can be hooked up to your garden hose and sprayed on the lawn.


If you see the worms, don’t hesitate!  They call them armyworms because they travel in troops and march along, eating your entire lawn and then moving on to the next one!  They are BAD little guys!!
