10 Best Garden Grub Killers 2026 in the United States

The Scotts GrubEx1 Season Long Grub Killer is a solid choice for homeowners looking to protect their lawns from grubs and other pests. It contains granules that are easy to apply, especially when used with Scotts spreaders. One application in the spring or early summer can cover up to 10,000 square feet, providing up to 4 months of protection.

This makes it quite efficient in terms of both labor and coverage area. The product is not only effective against grubs but also targets a variety of other insects like armyworms, sod webworms, chinch bugs, and beetles, which can be advantageous for comprehensive lawn care.

While the product is highly effective in preventing root and turf damage caused by insects, it would be beneficial to check the specific active ingredient and any related safety information to ensure it aligns with your environmental and pet safety preferences.

The ST. Gabriel Organics Milky Spore Granular Natural Bacteria Japanese Beetle Grub Killer is a garden product designed to help control grub infestations in lawns and gardens. It uses Milky Spore, a natural bacteria, as its active ingredient to target and kill Japanese beetle grubs. This makes it an eco-friendly option for those looking to manage pests without resorting to harsh chemicals.

One of its standout features is the long-lasting protection it offers; a single application can provide up to 10 years of effective control, which is a huge plus for busy gardeners who prefer low-maintenance solutions. Additionally, it's safe for pets, children, and beneficial insects, aligning well with the need for products that promote a balanced ecosystem and are gentle on the environment. Application is straightforward, thanks to its granular form that can be easily applied using a lawn spreader.

This product also contributes to the health of your lawn by eliminating grubs that cause damage, leading to thicker and healthier grass growth. However, the product's effectiveness is specifically geared towards Japanese beetle grubs, so if you have other types of grubs or pests, this may not be the best fit. Additionally, some users might find the upfront cost higher compared to other chemical-based grub killers. This product is best suited for those who are looking for a long-term, environmentally friendly solution to maintain a healthy lawn free from Japanese beetle grubs.

Scotts GrubEx1 Season Long Grub Killer uses chlorantraniliprole as its active ingredient, which is effective in targeting grubs and several other common lawn pests such as caterpillars and Japanese beetles. One of its biggest advantages is that a single application can protect your lawn for up to four months, covering a large area of 5,000 square feet, making it convenient for those with medium to large lawns. The granular form is easy to apply on a dry lawn during spring or early summer, which helps kill grubs early before they cause visible damage.

This product is strong against multiple pests and should be used carefully around pets and wildlife, as with most insecticides. Users who prioritize eco-friendliness or have pets that roam freely may want to take extra precautions or consider alternative treatments.

The product comes from a reputable brand known for lawn care and is made in the USA, which may reassure buyers about quality. It is not a quick fix for already damaged lawns but rather a preventive treatment. If you’re looking for a reliable, season-long solution to protect your grass from grub damage with minimal reapplication, Scotts GrubEx1 is a suitable choice. Just keep in mind to follow application instructions closely to minimize any risks to non-target insects or animals.
