Grubex spreader settings refer to the recommended application rates and settings for the efficient and effective distribution of Grubex, a popular insecticide used for controlling grub infestations in lawns and gardens. These settings play a crucial role in ensuring that the product is applied evenly and at the correct dosage, maximizing its effectiveness while minimizing waste.
Grubex, produced by renowned manufacturers in the pest control industry, is specifically formulated to target and eliminate grubs, which are the larval stage of various beetles. These pests can cause severe damage to lawns, as they feed on grassroots, leaving unsightly brown patches and weakening the overall health of the turf. To combat this problem, Grubex offers a potent solution that kills grubs upon contact, effectively protecting lawns from their destructive activities.
However, applying Grubex in the correct manner is essential to achieve the desired results. This is where spreader settings come into play. Spreader settings provide a standardized guide to determine the appropriate rate at which the insecticide should be distributed across the lawn. These settings take into account factors such as the size of the lawn, the type of spreader being used, and the concentration of Grubex in the product.
Grubex, a product developed by The Scotts Company LLC, is both an insecticide and soil treatment. It is widely recognized for its association with Scotts lawn spreaders. This versatile solution serves as an effective preventive measure for safeguarding your lawn against grubs and various other insect pests.
If you’ve been grappling with pest or insect issues in your lawn and have been attempting to address it independently, without seeking professional assistance, there’s a good chance that you’ve received recommendations to give Grubex a try. Grubex has gained significant popularity as a widely-used solution for insect problems throughout the United States. While it is true that using Grubex successfully necessitates understanding the appropriate spreader settings, these settings are also contingent on the type of spreader you employ for the application. It is crucial to note that without the correct setting, achieving favorable outcomes from each application is unlikely.

It targets the grubs in lawns and gardens, preventing them from causing damage and ultimately eradicating their populations. Grubex is effective against a wide range of grub species, including:
- White grubs (including larvae of):
- Japanese beetle
- Asiatic garden beetles
- Aphodius spp
- European chafers
- Green June beetles
- May/June beetles
- Northern masked chafers
- Oriental beetles
- Southern masked chafers
- Caterpillars
- Armyworms
- Cutworms
- Sod webworms
- Annual bluegrass weevils
- Billbug grub

- Chinch bugs
Grubex is formulated to target and eliminate these types of grubs. It works by disrupting the grubs’ nervous system upon contact, leading to their elimination. By controlling the grub populations, Grubex helps protect lawns and gardens from the damage caused by these pests, including brown patches, weakened turf, and overall lawn deterioration.
It’s important to note that Grubex is specifically intended for grub control and may not be effective against other types of insects or pests. If you are dealing with a different pest issue, it’s recommended to consult with a pest control professional or refer to appropriate insecticides specifically designed for that particular pest.
How and When to Apply Scotts Grubex
In addition to the customary guidelines such as selecting an appropriate spreader setting and cleaning the spreader after use, it is crucial to emphasize that Grubex should only be applied to dry lawns. Ensuring that the lawn is dry prior to application is an important consideration to achieve optimal results with Grubex.
If it becomes necessary to water your lawn before applying Grubex, it is important to allow the lawn to dry completely before proceeding with the application. Typically, this drying process takes approximately 2 to 5 days. The reason for this precaution is that after applying Grubex, you will need to water the lawn again. By ensuring the lawn is dry before application and then watering afterward, you can minimize the risk of erosion and prevent any unnecessary issues that may arise.
It is important to note that Grubex should be applied once a year, specifically during the spring to early summer timeframe. This timing is crucial as it targets grubs that are emerging from their winter hibernation as well as newly hatched grubs in the soil. It is during this period that beetles lay their eggs. By applying Grubex during this window, you effectively eliminate these early-stage grubs and prevent potential infestations.
Can I Use Grubex with Fertilizer?
Yes, it is generally safe to use Grubex in conjunction with fertilizer. In fact, many lawn care professionals and homeowners prefer to apply Grubex and fertilizer together to promote both grub control and the health of their lawns. This approach allows for the convenience of treating for grubs and providing essential nutrients to the turf in a single application.
When combining Grubex with fertilizer, there are a few considerations to keep in mind:
-
Read and follow the instructions: Always carefully read and follow the instructions provided on both the Grubex and fertilizer product labels. They will provide specific guidance on application rates, timing, and any precautions or restrictions.
-
Choose compatible products: Select a fertilizer that is compatible with Grubex. Ideally, opt for a slow-release or controlled-release fertilizer, as these provide a gradual and steady release of nutrients over time. This helps to avoid excessive growth spurts or nutrient imbalances.
-
Timing: Coordinate the application of Grubex and fertilizer based on the recommended timing for each product. Grubex is typically applied in spring or early summer before grubs become active, while fertilizers may have different recommended application windows. It’s best to follow the specific instructions for each product and consider local climate and growing conditions.
-
Application method: Depending on the specific products and the preferences of the applicator, Grubex and fertilizer can be applied separately or mixed together in the spreader. Mixing them in the spreader ensures even distribution and simplifies the application process. However, if the products have conflicting instructions on mixing, it’s best to apply them separately, adhering to the recommended rates and methods for each product.
Remember, always exercise caution when applying any lawn care products and follow the instructions provided by the manufacturers. If you have any concerns or questions about using Grubex with fertilizer, it’s advisable to consult with a lawn care professional or contact the product manufacturers for specific guidance.
How to Use Grubex with Children or Pets in the Home
Post-application procedures typically remain straightforward when living alone. In such cases, tasks like washing hands, cleaning the spreader, and clearing the measured pavement are usually sufficient. However, the situation can become more complex when there are children or pets in the household.
In such instances, it is crucial to ensure that they steer clear of the treated lawn or any areas where the insecticide has been applied until it has completely dried. Additionally, it is important to be vigilant and promptly address any spillage on driveways or sidewalks by thoroughly washing those areas as well. By taking these precautions, you can prioritize the safety of children and pets and minimize any potential risks associated with the insecticide.
