Dylox 420 SL Insecticide provides fast acting grub control. Dylox 420 SL Insecticide treats surface feeding insects on lawns, landscape and recreational turf, such as golf courses. After irrigation or rainfall, grub control is established in as little as 24 hours and penetrates thatch up to ½ inch thick. Dylox 420 SL Insecticide works by both contact and ingestion. This kills insects on landscape flowers, trees and shrubs instantly within contact. This also works on lawns and turf against damage from predators such as birds, raccoons and skunks. 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.

Dylox 402 SL for white grubs
By Brent in Midland, MI on 05/14/2014
We tried GrubEx, Diazinon, and most other big box store products over the past 5 years or so with no noticeable impact on our lawn's grub infestation. This product killed the grubs overnight, after watering in. Birds no longer dig out grubs to eat, they just feed on surface insects now. Our lawn is coming back nicely. I applied this in May when the grubs were quite large and the product worked perfectly. I used the label suggested rate of 6.9oz/1000sqft.

QWhat is the ratio of Dylox Concentrate per gallon of water?
How many gallons of Dylox does each 2.5 gal of the concentrate make.
AThe mixing ratio for Dylox 420 SL Insecticide is dependant 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 specified dosage of DYLOX 420 SL Turf & Ornamental Insecticide in sufficient water to provide adequate distribution during application to lawn, turf or groundcover area.

QIs two gallons of water really the right amount for 1000 sq. ft.??
This question and answer is currently in the Q&A section, but I am curious if the amount of water is correct.
AYes, with Dylox 420 SL Insecticide, you will need to use enough water that is going to give complete coverage of the soil or turf. Two gallons of water will ensure that the product is getting into the soil properly. The type of equipment used will determine the concentration required. Please let us know if you have any additional questions.

I have grass seeds on the ground that have not yet germinated. If I spray Dylox before germination while it kill the grass seeds? If so, how long should I wait before spraying?
ADylox 420 SL Insecticide can be applied while you are seeind. In fact it would be a good thing, since you would be watering more often.
