Army Worm and Grub prevention can be done. However if you only have our Weed and Feed program which most people do. Then you will not get this application. The product we use is fairly new on the market and is called Acelepryn. This is not harmful to Bees like most other products used for this. In the 2016 Army Worm invasion we found that every person that received this product for grub control also had no army worms. Army worms come every year in the fall around August through September depending on the weather that summer. They WILL NOT KILL YOUR LAWN! like some people are saying. They eat the green off the top of the grass and then die off. Most people that get these pest have gotten them before but didn't even know it unless they had enough population to show browning.
