Pros

  • Effectively kills most weeds within 24 hours, with visible drying and control when used properly.
  • Uses a surfactant that helps the formula adhere longer to weeds, improving overall effectiveness.
  • Works much faster and better than common vinegaased, pet-friendly weed killers.
  • Comes with a reusable sprayer and wand powered by 2 AAA batteries, making application convenient and easy.
  • The spray wand folds out effortlessly and has an accessible battery compartment for quick replacements.
  • Refill bottles are compatible with the original sprayer, simplifying refills and reducing waste.
  • Safer alternative to harsh chemical herbicides, making it suitable for homes with kids, pets, or wildlife.
  • Safe for well water supplies and around vegetable gardens.
  • Mild herbal odor that dissipates quickly, though it may be unpleasant during application.
  • Tube design inside the container helps extract nearly every drop, minimizing product waste.

Cons

  • Less effective on mature wild grasses and tougher, established weeds; may require multiple treatments.
  • Slower acting compared to strong chemical herbicides like Roundup, with some users noting it takes longer than one hour to see full results.
  • Strong herbal smell during application can irritate eyes and may require wearing gloves and a mask.
  • Although considered safe for pets, it’s recommended to keep them away during spraying due to odor and potential irritation.
  • Somewhat expensive relative to generic alternatives, though many consider it worth the price.

Bottom Line

The Spruce Weed Killer Spray offers a safer, pet- and kid-friendly weed control solution with solid performance on most common weeds, especially younger ones, and a reusable, user-friendly sprayer setup. If you are looking for a non-toxic option that works fairly quickly and don’t mind occasional reapplication for tougher weeds, this kit is a great fit. However, if you want something ultra-fast or stronger on old grasses, more potent chemical-based options might be better suited. For a balance of safety and effectiveness, the Spruce kit is worth considering.
