Many homeowners assume that a healthy, green lawn naturally wards off invasive grasses. The truth is, some aggressive weeds, like Bermuda grass, treat your prized turf like an all-you-can-eat buffet.
It takes more than good intentions to keep these runners from creeping across your property. To help you regain control, I have assembled the Best Bermuda Grass Killers that strike the right balance of potency and precision.
Key Takeaways
- Prioritize selective herbicides if you need to eliminate weeds while keeping your desirable turf grass alive.
- Check the active ingredients for compatibility with your specific grass type to avoid accidental damage to your lawn.
- Consider a concentrate if you have a large yard, as mixing your own solution is often more cost-effective than buying individual ready-to-use bottles.
- Ensure the product label specifies that it is effective against Bermuda grass, as many general weed killers fail to suppress this stubborn species.
- Verify the required application method, whether you prefer a hose-end sprayer for speed or a spot-treatment bottle for precision.

Ortho Grass B Gon Killer
If you have Bermuda grass popping up in your flower beds or near your prized shrubs, this is the tool you want. It functions like a surgical strike because it targets grassy weeds without harming your broadleaf plants.
You should use this when you need to be highly selective near sensitive areas. Just keep in mind that it is not meant for broad lawn applications, so do not spray it over your entire yard.

Ortho WeedClear Ready-to-Spray
Think of this as your general purpose defense for a clean lawn. It excels at clearing out common weeds that ruin a uniform look, though it is more effective on broadleaf varieties than stubborn, encroaching Bermuda grass.
Apply this with a standard garden hose to cover large areas quickly. It works best when the weeds are small and actively growing, but do not expect it to eliminate deep-rooted invasive grasses overnight.
- Brand Name:Ortho
- Product Type:Weed killer
- Total Capacity:32 fluid ounces
- Application Method:Hose-end sprayer
- Formula Form:Liquid concentrate
- Additional Feature:Visible results in hours
- Additional Feature:Rainproof after one hour

Spectracide Weed Stop Concentrate
When you need to clear an area quickly, this concentrate provides a serious punch. It is designed to work fast, making it a favorite for those who dislike waiting weeks for results.
It handles many different weed types, but you must be careful with your application rate. Because it is a concentrate, you need to mix it accurately with water in a separate sprayer to avoid damaging your healthy turf.

- Total Capacity:32 ounces
- Application Method:Pump sprayer
- Formula Form:Liquid concentrate
- Additional Feature:Starts working immediately

-
Scotts Turf Builder Triple Action
This product is less of a spot-killer and more of a preventative strategy. It feeds your grass while keeping new weeds from taking hold, which helps your desired turf crowd out invaders like Bermuda grass.
It is best applied as part of a regular schedule rather than as a quick fix for an existing infestation. Use it when you are ready to invest time into thickening your lawn density.
- Brand Name:Scotts
- Product Type:Weed and feed
- Total Capacity:11.31 pounds
- Application Method:Broadcast spreader
- Formula Form:Granular

-
Fertilome Over The Top Killer
This is a heavy-duty option for getting rid of unwanted grasses in areas where you cannot afford to kill your flowers. It acts as a systemic agent, meaning it moves through the leaves down into the roots.
It is extremely effective, but you must add a surfactant to help it stick to the waxy surfaces of grass blades. If you skip that step, the liquid will likely bead up and roll off without doing its job.
- Brand Name:Fertilome
- Product Type:Selective grass killer
- Total Capacity:8 ounces
- Application Method:Pump sprayer
- Formula Form:Liquid concentrate
- Additional Feature:Kills many grass types
- Additional Feature:Effective in landscapes
- Additional Feature:Concentrated formula
-
BioAdvanced All-In-One Killer
This concentrate is designed to tackle a wide range of lawn invaders, including some of the tougher grasses that other products ignore. It serves as a reliable middle ground between specialized grass killers and general weed preventers.
Be mindful that it is highly potent. Use it only on established lawns, and keep it away from your garden beds, as it does not differentiate between good plants and bad weeds.
- Brand Name:BioAdvanced
- Product Type:Weed and grass killer
- Total Capacity:40 ounces
- Application Method:Pump sprayer
- Formula Form:Liquid concentrate
- Additional Feature:Rainproof in one hour

Frequently Asked Questions
How many applications will I need to get rid of it for good?
Bermuda grass is persistent, so you should expect to perform two to three treatments. Space your applications about three to four weeks apart to catch any resilient roots that survived the first round.
Can I use these products near my vegetable garden?
You must be extremely careful near food crops. Drift from a spray can kill your tomatoes or herbs, so use a physical barrier like a piece of cardboard to block the spray. It is safer to choose a natural-based product if you are working within a few feet of your vegetables.
Why does the grass turn yellow instead of dying immediately?
Most herbicides work by disrupting the plant's internal systems rather than burning it on contact. The yellowing is a sign that the chemical is working and the plant is starting to starve. Be patient and wait at least ten to fourteen days before you decide if a second application is necessary.
Should I mow the lawn before I apply the herbicide?
It is actually better to let the grass grow a bit before you start. You need plenty of leaf surface area for the plant to absorb the chemical effectively. Mowing too soon can reduce the amount of herbicide the grass takes in, making your efforts less effective.
Is there a way to stop it from coming back next year?
You can apply a pre-emergent herbicide in the early spring to stop seeds or dormant stolons from taking root. Keep your soil healthy and maintain a thick layer of mulch in your flower beds to choke out any remaining sprigs. Consistency is your best weapon against this aggressive grower.
