Ortho Lawn and Landscape Insect Killer Concentrate 32 oz.

If your main concern is a few bugs near a doorway, a targeted treatment may be enough, if insects are showing up across the lawn, around the foundation, or in planted areas, this concentrate is designed for broader outdoor coverage. It lists ants, ticks, mosquitoes, fleas, spiders, and many other pests among its targets. The product starts working within minutes, while the longer-lasting claim is more specific: up to three months for ants, spiders (excluding black widows), and American dog ticks. You’ll need to mix it with water and apply it with a tank sprayer or Ortho Dial N’ Spray, following the label.

Where it shines

This is an outdoor treatment for several parts of a home landscape, rather than a ready-to-use spray for one small spot. The listed coverage is up to 5,300 sq. ft. of lawn, 1,400 sq. ft. of foundation or perimeter, or 2,700 sq. ft. of foliage. Those are different application areas, not one combined coverage figure, so match the stated area to the surface you plan to treat.

A practical use case: when ants are appearing along the edge of a lawn and mosquitoes are a concern near shrubs, one concentrate is intended for use across lawn, perimeter, and foliage areas. If you prioritize broad outdoor coverage, that flexibility may be useful, if you prefer a no-mix product for quick spot treatment, the need to dilute and spray is a drawback. Worth considering if you want one product labeled for a range of outdoor pests and surfaces.

Key points

The product lists 235 bugs, including armyworms and periodical cicadas as well as ants, ticks, mosquitoes, fleas, and spiders. Its “within minutes” statement describes how quickly it starts killing, it does not mean every listed insect receives the same three-month control. That longer-lasting claim applies to ants, spiders other than black widows, and American dog ticks.

It can be used on lawns, around the home perimeter, and on ornamentals, flowers, trees, shrubs, and listed vegetables and fruit trees. Read the label for mixing and application directions, especially before treating edible plants. Coverage depends on the area being treated: without that measurement, it’s harder to tell how much of the stated coverage applies to your project. The product is a concentrate, so it also requires suitable spray equipment rather than direct application from the bottle.

Best use cases

This may suit homeowners treating a lawn or several landscape areas for multiple listed pests, particularly when a longer control window for the specified ants, spiders, and American dog ticks matters. It is less aligned with someone who only needs a small, ready-to-spray application or wants a product that requires no dilution. It’s not for you if mixing and applying with a sprayer doesn’t fit your approach to outdoor pest control.

Is it worth it?

The case for this Ortho concentrate is its combination of multiple labeled outdoor treatment areas, a broad list of targeted bugs, and clearly stated coverage options. The trade-off is that those coverage figures vary by surface, and the three-month claim does not apply to every pest listed. Check the treatment area and label directions before choosing it. Buy it when you need a mix-and-spray treatment for lawn, perimeter, or foliage, choose a simpler spot-treatment format if you only need to handle an isolated area.
