Safe Pest Control for Dogs and Children

Fall armyworms are surface feeders. They might conceal in the heat of the day, but they live above ground and feed upon the turf blades. You will not need to dig in the soil to find them. Fall armyworms are small and green with a black head when they hatch, however they grow quickly and become darker with age.

See image 2. Evaluate the turfgrass health and vigor, the size of the caterpillars, the amount of feeding damage, and the time till anticipated frost when identifying if insecticide treatment is warranted. Carefully scout to determine the number, size, and circulation of fall armyworms and the condition of the turfgrass. Little armyworms (greenish in color) are a lot easier to manage than caterpillars nearing their mature length of 1.5 to 2 inches.

Healthy turfgrass might endure low to moderate quantities of damage and can recover with watering and fertilization. See Recovery below. Mow high turfgrass before treatment to enhance insecticide coverage. Collect the clippings that build up on the surface area. Water lightly numerous hours before treatment to increase larval activity on the soil surface.

See Table 1. Pyrethroid resistance has actually been reported in other parts of the nation. If there is no fast control of fall armyworms after using a pyrethroid, consider using a different class of insecticide, or employ a lawn care business to use a chlorantraniliprole or tetraniliprole compound. Azadirachtin insecticides (Neem oil) can offer control of little larvae and are accredited organic.
