The Ortho BugClear Lawn Insect Killer1 is a versatile insecticide that targets a wide range of lawn pests including ants, spiders, ticks, fleas, grubs, beetles, and armyworms. It comes in granular form, which makes it easy to apply using a Scotts Spreader. Users will appreciate that this product covers a large area of up to 16,500 square feet, making it suitable for sizable lawns and gardens.

One of the standout features is its ability to provide up to 6 months of protection against ants, although it does exclude certain types such as pharaoh, carpenter, and harvester ants. This extended control can save users from frequent reapplications, adding to its convenience. Additionally, it is suitable for use on lawns, ornamental plants, home perimeters, flower beds, and specified vegetable plants, offering flexibility in its application. However, users should ensure they water the area after application to activate the granules effectively.

In terms of safety, it is important to follow the instructions closely to avoid any potential harm to pets or humans. While the product is effective against a broad spectrum of insects, it has a residual environmental impact, which might be a concern for eco-conscious users. The Ortho BugClear Lawn Insect Killer1 is a reliable choice for those dealing with various lawn pests.

Scotts GrubEx1 Season Long Grub Killer is a granular insecticide that uses Chlorantraniliprole as its active ingredient to target grubs and other lawn-damaging insects such as caterpillars, chinchbugs, and beetles.

This product is suitable for large lawns, as one 14.35 lb. bag can cover up to 5,000 sq. ft. It is designed to be applied to a dry lawn in the spring or early summer, which is convenient for seasonal lawn maintenance schedules.

However, the granular form requires careful application to ensure even coverage. Safety-wise, it’s important to follow the instructions closely, especially if you have pets or children who play on the lawn. While the product is effective, its environmental impact should be considered, as it involves chemicals that might affect the surrounding ecosystem if not used properly. This product is best suited for homeowners with larger lawns who are looking for a long-term, once-per-season solution to grub and insect control.

With a coverage area of up to 6,400 square feet, it is suitable for large lawns and landscapes.

Users need to mix it with water and apply it as directed on the label. Once the treated area is dry, it is safe for children and pets to re-enter, which is a significant safety advantage. The product enjoys high customer ratings and is popular in the Patio, Lawn & Garden category, being ranked #3 in Insect & Pest Repellent Spray Concentrates.

However, potential users should be aware of the environmental impacts associated with insecticides containing chemicals like Gamma Cyhalothrin. While it is effective in pest control, it may pose risks to non-target organisms and should be used responsibly. Additionally, the product does not provide immediate results and might require some time before its full effects are noticeable. It is a potent solution for those dealing with significant insect problems in their lawns but should be used with care considering its chemical nature.
