The product comes in granule form, which is easy to apply using a Scotts spreader, helping ensure even distribution.

It works over four months, targeting grubs at their young stage before they can cause serious root damage, which helps keep your grass stronger. Besides grubs, it also kills other common lawn pests like armyworms and chinch bugs. Its simple one-time application and good coverage make it user-friendly, especially for those who prefer low-maintenance lawn care.

This product is a solid choice if you want long-lasting grub protection and have a larger lawn, but users should consider environmental factors before using it.

The Ortho BugClear Lawn Insect Killer1 is a versatile product designed to address a wide range of lawn pests, including grubs, ants, spiders, ticks, fleas, beetles, and armyworms. With an active ingredient that kills insects by contact, it provides six months of control for certain pests, which is a significant benefit for long-term lawn maintenance.

One of its strengths is the broad coverage area, as the 10 lb. container treats up to 16,500 sq. ft., making it suitable for large lawns and garden spaces. The application is straightforward using a Scotts Spreader, and the granules need to be watered in after spreading, which helps integrate the product into the soil effectively. The timing of application is crucial – it should be applied at the first sign of insect activity or damage for maximum effectiveness.

The product appears user-friendly with clear instructions, but the weight of the container (10 pounds) might be cumbersome for some people to handle. The environmental impact is a consideration, as the product does not specify being organic or eco-friendly, which might be a concern for environmentally conscious users. This product is most beneficial for homeowners with sizable lawns looking for a comprehensive solution to a variety of lawn pests, including grubs.

The product covers a large area of up to 10,000 square feet, which is suitable for sizable lawns or gardens. The active ingredient, Trichlorfon, is effective for rapid pest elimination, but it's important to handle it carefully due to its chemical nature. The granule form makes it relatively easy to spread across your lawn using a spreader, which simplifies the application process. However, it is essential to apply the product as soon as grubs are detected to prevent further damage.

One limitation to note is that the product is not available for sale in California and Maine, which could be a drawback for residents in those states. Additionally, while the product is effective, its chemical composition may have some environmental impacts, so users should follow the application guidelines strictly to minimize any negative effects. Despite these considerations, the BioAdvanced 24 Hour Grub Killer Plus remains a popular choice for effective and quick grub and insect control.
