Dylox 420 SL Insecticide, manufactured by Bayer, is a broad-spectrum insecticide that targets turf insects and delivers fast acting grub control. Dylox 420 SL Insecticide treats surface feeding insects on lawns, landscape and recreational turf, such as golf courses.

This product has a dual action formula, working via contact and ingestion. Best of all will not damage landscape flowers, trees and shrubs when sprayed upon to control the pests that are feeding on those plants.

Dylox 420 SL Insecticide is known to be the best product available for third instar grubs because it works later in the season and provides a longer effective application window than other competitors

Tools Needed

To use Dylox 420SL Insecticide you will need either a hose end sprayer, handheld pump sprayer, backpack sprayer, or spray rig. For smaller sized residential treatments, we recommend a handheld 1-gallon pump sprayer or a 4-gallon backpack sprayer.

How to Use

  • Step 1: Measure the square footage of the area you will be treating. You can do this by multiplying the length times width. After you have the square feet to be treated, divide by 1,000 to get the number of finished gallons of spray you will need to use. For example, if you have 3,000 sq.ft. to treat you will need (3,000/1,000) 3 gallons of solution.
  • Step 2: Determine your mix rate for the target insect. Dylox 420SL Insecticide can be mixed between 4.6 to 6.9 ounces per gallon of water. Specifics depend on the insect being targeted.
  • Step 3: Mix the required amount of chemical with water in your sprayer. Shake well to ensure the product is properly agitated and mixed.
  • Step 4: Apply the product according to labeled directions in the areas where you are having pest infestations. Completely cover foliage. If spraying a tree, treat stems and trunks up to 10 feet from the ground. You can use a coarse spray, drench, or broadcast.

Where to Use

Dylox 420SL Insecticide is meant to only be for outdoor use to control pests around trees and turf. You can treat areas outside of residences, places of business, hospitals, golf courses and anywhere you have insects that are doing damage to outdoor plants.

When to Use

Use Dylox 420SL Insecticide upon recognizing a pest infestation around your yard or if you notice turf or tree damage. This is typically around the spring and summer months when pest activity is very high.

Safety Information

Be sure to wear proper personal protective equipment (PPE) when applying. Keep pets and children away from treated outdoors areas until the product has completely dried.

Special Considerations

For best results, you will need to constantly agitate the sprayer to ensure it's well mixed.
