What customers say
Customers highly value the Spectracide Concentrate for its potent, fast-acting weed killing power, often seeing results within 24 hours. It proves effective against tough vegetation like poison ivy. A major draw is the excellent value; being a concentrate allows users to mix large volumes affordably, significantly lowering the cost per application compared to ready-to-use options. Satisfaction is high due to this cost efficiency and performance. Users consistently emphasize the need for precise, careful application because the formula is nonselective and harms desirable plants. While the initial kill is fast, some deeply rooted perennials may need a second treatment for complete eradication. Overall, it is viewed as a high-performance solution when handled correctly.
Know before you buy
You can replant flowers, trees, and shrubs as soon as one day after the application, provided the treated weeds have been addressed.
This is a non-selective herbicide, meaning it will kill any vegetation it touches. Use extreme caution when spraying near desirable plants, as accidental contact can cause damage or death to those plants.
The formula becomes rainproof just 15 minutes after application. If it rains shortly after this window, the effectiveness of the treatment should not be compromised.
You should mix between 3 and 7 fluid ounces of concentrate per gallon of water, depending on the density of the weeds you are targeting. One gallon of this mixture typically covers 300 square feet.
For optimal results, apply this product when temperatures are at least 60°F. Application in cooler temperatures may significantly slow down the weed-killing process.
Yes, this product is highly effective for hardscapes like driveways, walkways, and patios. It is designed to kill weeds and grasses down to the root in these areas.
