How to stop Army Worms
Armyworms show up in August or September and their numbers can grow rapidly. If your lawn appears to be dry and thinning, or you begin seeing brown patches, you could have Armyworm problems and the damage could get worse quickly. An advance indicator could be several birds feeding in your lawn. Depending on the damage, grow back times could be up to 1 month. Another advance indicator to watch for is armyworm moths flying around your lawn at night as your car headlights shine across your lawn. There can be so many that it looks like a light snow. This is a dead giveaway that they are laying eggs which soon will hatch into the voracious eating larvae.
Control Army Worms
Solving a lawn pest problem starts with identifying the pest. If you think you have an Army Worm infestation, look down onto a thinning area of lawn for the worms. They are about an 1 ½” long with a “Y”on their face. Fortunately, armyworms are easy to control with insecticides. It can be applied with a fertilizer spreader, but spraying liquid insecticide to control Army worms is the most effective. If your neighbors are having army worm infestations, chances are you will too. As a preventative measure, you could purchase insecticide and be ready to apply the minute you see the caterpillars marching through your lawn. Another option is to call a chemical licensed lawn contractor to treat your lawn with the appropriate insecticide to kill Armyworms.
“The good news is that armyworms will not hurt your lawn permanently. Fall armyworms rarely kill grass but some lawns may be severely weakened.”
