10 Best Weed Killers for Lawns of 2025

Tackle those weeds before they’ve even made an appearance. This is one of the best pre-emergent weed killers on the market for multiple reasons.

For one, it does prevent weeds. You can use this on nurseries, lawns, turfs, golf courses, and more. In terms of prevention, this works for henbit, knotweed, spurge, foxtail, annual bluegrass, chickweed, and goosegrass.

Suitable for use in spring or fall, each time you use it, this weed killer provides enough control to last throughout the season.

The active ingredient is prodiamine, which is a popular choice for pre-emergent herbicides ⁽¹⁾. It works by controlling weeds before they have sprung up — by stopping them from germinating. Even using it twice a year is enough to prevent weeds from taking over your lawn.

If you’ve left it too late and the weeds are already springing up, you need a post-emergence weed killer. Look no further than the Compare-N-Save concentrate grass and weed killer.

It uses glyphosate, an effective post-emergent herbicide. It kills down to the root when applied properly.

Make sure to spray the foliage, but work to avoid spraying plants you don’t want to kill. The glyphosate is then absorbed through the foliage as it travels down the root to kill the plant.

You can expect results in two to four days, so be patient. Before long, your lawn should be looking a lot neater!

You can use this for killing weeds, grass, stumps, brush, and vines. It’s suitable across lawns, driveways, buildings, fences, and walkways.

This particular bottle makes up to 85 gallons of spray solution when diluted. That covers up to 25,000 square feet! So you’re definitely getting a lot for your money because this is a pretty budget-friendly option.

I wouldn’t choose ineffective products for my top 10 list. But if you’re looking for something well-reviewed by thousands of customers who rave about its effectiveness, check out Roundup Weed and Grass Killer.

While you can certainly use this to kill your weeds, you can also use it to clean indoors as well. It’s suitable for cleaning oven doors, drains, tub scum, calcium deposits, and more.
