If 4-5 per square foot are found, mow the lawn to a 2 inch height and apply carbaryl or permethrin according to label directions.
Inspect your lawn every other day, looking closely at the grass blades and crowns for feeding damage and the presence of small black/grey caterpillars. The reason that these pests are so newsworthy is that they feed in big numbers and cause lots of damage to lawns, marching across in “army infantry like” fashion, leaving dead plants in their wake. The abundance of weather events has brought them to Nebraska. They normally are isolated to the southeastern region of the US and move north in storms. They feed on ryegrass, fescue, bentgrass and bluegrass. Feeding should begin in the next couple of days and continue for several weeks or longer.
Well, put your tray tables on the upright and locked position and fasten your seat belts! Egg masses (40 in one yard) have been found in Lincoln and moths are flying abundantly in Omaha. Many of you may recall the devastating outbreak of Fall army worms in Nebraska decades ago.
