Dylox 420 SL Insecticide is best applied when grubs currently present in the lawn and actively feeding. Apply at 6.9 fl oz in 2 gallons of water per 1000 sq ft. Refer to page 7 on the product label for more information.
For preventative grub control, Merit 0.5 G Insecticide Granules or Merit 2F Insecticide is recommended to get early control of grubs in the lawn. Apply in mid June – mid July prior to grub egg hatch. Typically grub egg hatch occurs in late July through August however timing can vary depending on the region.
View our White Grub Treatment Guide for more information and contact your County Extension Office for the most accurate timing recommendations for your area.
The mixing ratio for Dylox 420 SL Insecticide is dependent upon what you are treating for. Typically, you would use 4.6-6.9 oz per 1,000 square feet. Therefore, one 2.5-gallon jug of Dylox 420 SL Insecticide will cover 46,000-69,000 square feet, depending on the ratio used. The amount of water is not as important as making sure to mix the specified dosage of DYLOX 420 SL Turf & Ornamental Insecticide in sufficient water to provide adequate distribution during application to lawn, turf, or groundcover area.
