4 Best Grub Killer For Lawns 2026 in the United States

The Scotts GrubEx1 Season Long Grub Killer appears to be a solid choice for preventing turf damage caused by grubs and other lawn pests. One of its primary strengths is its active ingredient, Chlorantraniliprole, which is effective in killing young grubs and preventing their development for up to 4 months. This makes it convenient for lawn maintenance with just one application in the spring or early summer, covering a substantial area of 5,000 sq. ft.

The granular formulation allows for easy application with a spreader on a dry lawn, ensuring even distribution and effective pest control. Additionally, it targets a wide range of insects, including armyworms, chinchbugs, May/June beetles, and Japanese beetles, which can be beneficial for comprehensive lawn care.

A potential drawback is the environmental impact of chemical insecticides, which may not be suitable for those seeking organic or eco-friendly garden solutions. Furthermore, the product's weight of 14.35 lbs. might be cumbersome for some users to handle. In conclusion, Scotts GrubEx1 is effective and convenient for users needing a reliable solution to protect their lawns from a variety of pests, though it may not align with environmentally-conscious gardening practices.

The Bayer Merit 0.5 Granular Systemic Insect Control is a reliable grub killer for lawns that comes in a 30-pound bag. Its active ingredient, Imidacloprid at 0.5%, is effective against a wide range of insects, including grubs, making it suitable for use on turfgrasses, trees, shrubs, evergreens, flowers, foliage plants, and ground covers. One of the key strengths of this product is its broad application range, allowing users to protect various parts of their garden and lawn from pests.

Additionally, it has received positive customer reviews, with a rating of 4.6 out of 5 stars from 570 ratings, indicating a high level of satisfaction among users. The product is not discontinued and is backed by Bayer, a reputable manufacturer, ensuring its availability and reliability. However, users need to be mindful of the application limit, as it cannot exceed 80 pounds per acre per year to avoid overuse of the active ingredient. Being in granule form makes it easy to apply, but it might require careful handling to ensure even distribution.

In terms of environmental impact, while Imidacloprid is effective, there are concerns about its potential effects on beneficial insects like bees. Therefore, users should apply it responsibly and follow all guidelines to minimize any negative impacts on the environment. The product's large coverage area and systemic action make it a strong contender for those looking to manage grubs and other pests effectively in their lawns and gardens.

This product utilizes lambda-cyhalothrin as its active ingredient, which is known for its effectiveness in killing a wide range of lawn pests. One of its biggest strengths is its season-long protection, starting to work immediately upon application and continuing to guard your lawn throughout the season. This can be very convenient for those who don’t want to reapply treatments frequently.

Additionally, it covers a substantial area, treating up to 5,000 square feet, making it suitable for medium to large lawns. The granule formulation is easy to spread, which can be a plus for ease of application. However, there are some environmental considerations to keep in mind, as products containing chemicals like lambda-cyhalothrin can have negative impacts on non-target insects and potentially on the surrounding ecosystem.

It's also worth noting that it is manufactured in the USA by SBM Life Science, and its compact package dimensions make it easy to store. For those prioritizing eco-friendliness, however, exploring more natural alternatives might be beneficial. In essence, this product is well-suited for homeowners looking for a reliable and long-lasting solution to grub and insect problems in their lawns.
