Scotts GrubEx1 Season Long Grub Killer, Protects Lawns Up to 4 Months, 5,000 sq. ft., 14.35 lbs.

Scotts GrubEx1 Season Long Grub Killer is designed to help homeowners protect their lawns from grubs and other insects such as caterpillars and beetles. The active ingredient, Chlorantraniliprole, effectively kills grubs before they can cause significant damage to lawns. One notable feature is the product's long-lasting effect, providing up to 4 months of protection with just a single application. This is especially convenient for those who prefer fewer applications throughout the season. Each 14.35 lb. bag covers up to 5,000 square feet, making it suitable for medium to large lawns.

The granular form of the product is easy to apply using a spreader on a dry lawn in the spring or early summer. This timing ensures grubs are targeted while they are still young and vulnerable. However, users should be aware that safety precautions are necessary, as the product should be kept out of reach of pets and children until it has been thoroughly watered into the soil and the lawn has dried.

While effective in controlling various insects, the environmental impact of Chlorantraniliprole should be considered, as it may affect non-target species and local ecosystems. This product is ideal for homeowners looking for an effective, long-lasting solution to grub problems but should be used with caution regarding safety and environmental impact.

Most important from
2659 reviews

Residual Effect
Provides excellent pest control but requires reapplication every two months for sustained effectiveness.

The Spectracide Concentrate Triazicide Lawn & Landscapes Insect Killer is a robust option for those looking to control lawn and landscape pests. One of its main strengths is its active ingredient, Gamma Cyhalothrin, which is effective against more than 260 lawn-damaging insects, including ants, crickets, and armyworms. This product offers significant coverage, treating up to 6,400 square feet of lawn, making it suitable for larger yards.

It also promises up to three months of pest control, which means less frequent applications are needed throughout the season. Mixing with water for application is straightforward, and once the treated areas are dry, it is safe for children and pets to return to the lawn. This safety feature is particularly important for families and pet owners.

However, it's worth noting that the product's environmental impact should be considered, as chemicals like Gamma Cyhalothrin can be harmful to beneficial insects and aquatic life if runoff occurs. Additionally, some users might find mixing and application slightly inconvenient compared to ready-to-use options. This insect killer is effective and offers extended control, making it an excellent choice for comprehensive lawn care, but users should be mindful of its environmental implications.

Buying Guide for the Best Liquid Grub Killers

Choosing the right liquid grub killer for your lawn or garden is essential to maintaining a healthy and pest-free environment. Grubs can cause significant damage to your grass and plants, so selecting an effective product is crucial. When picking a liquid grub killer, consider the following key specifications to ensure you get the best fit for your needs.
Active IngredientsThe active ingredients in a liquid grub killer determine its effectiveness against grubs. Common active ingredients include imidacloprid, chlorantraniliprole, and carbaryl. Imidacloprid is effective for long-term control and is often used in preventive treatments. Chlorantraniliprole is known for its low toxicity to non-target organisms and is also used for preventive measures. Carbaryl is a contact insecticide that provides quick results but may require more frequent applications. Choose an active ingredient based on whether you need immediate results or long-term prevention.
Coverage AreaThe coverage area indicates how much ground a single container of the product can treat. This is usually measured in square feet or acres. For small lawns or gardens, a product with a smaller coverage area may be sufficient. For larger properties, look for a product that offers extensive coverage to ensure you can treat the entire area without needing multiple containers. Assess the size of your lawn or garden to determine the appropriate coverage area for your needs.
Application MethodThe application method refers to how the liquid grub killer is applied to your lawn or garden. Some products come in ready-to-use spray bottles, while others may require mixing with water and using a garden sprayer. Ready-to-use options are convenient and easy to apply, making them ideal for smaller areas or for those who prefer a hassle-free solution. Products that require mixing may offer more flexibility in terms of concentration and coverage but can be more labor-intensive. Consider your comfort level with the application process and the size of the area you need to treat.
Residual EffectThe residual effect of a liquid grub killer refers to how long the product remains effective after application. Some products offer long-lasting protection, which can reduce the need for frequent reapplication. Others may provide quick results but require more regular treatments. If you prefer a low-maintenance solution, look for a product with a longer residual effect. However, if you need immediate results and are willing to reapply as needed, a product with a shorter residual effect may be suitable.
Safety for Pets and ChildrenSafety is a crucial consideration, especially if you have pets or children who frequently play on the lawn. Some liquid grub killers are formulated to be safe for use around pets and children once the product has dried, while others may require a longer waiting period before the area is safe for re-entry. Always read the product label for safety instructions and choose a product that aligns with your household's needs to ensure the well-being of your loved ones.
Environmental ImpactThe environmental impact of a liquid grub killer is an important factor to consider, particularly if you are concerned about the health of your soil, plants, and local wildlife. Some products are designed to be environmentally friendly, with low toxicity to beneficial insects and minimal impact on the ecosystem. If sustainability is a priority for you, look for products that are labeled as eco-friendly or have certifications indicating their environmental safety. This will help you maintain a healthy garden while minimizing harm to the environment.
