Bermuda grass, torpedo grass, nimble-will or Alexander grass cannot be selectively treated.
This is because there are no available herbicides on the market that will selectively kill those types of weeds without harming the healthy grass that surrounds them. Since these weeds cannot be selectively treated, our recommendation is to use a non-selective herbicide, such as “round up”, which will kill the entire area, including the healthy lawn around the areas that are heavy with weeds. Once the entire area is dead from the root up, re-sodding the area with new St. Augustine/Zoysia grass will be the best next step. If any of these weed varieties are present in your lawn and you chose not to re-sod with St. Augustine/Zoysi, in time, the weeds will continue to spread to other areas in your lawn, creating a bigger problem in the future.
It is possible for the variety of weeds mentioned above, to regenerate themselves in the same area of the newly laid sod. The best defense against weeds returning is to maintain a thick and vigorously growing St Augustine / Zoysia lawn. A great way to discourage weed growth is to mow the area more frequently. This will prevent the weeds from growing too tall and will cause the lawn to grow faster and thicker. You should never let weeds grow higher than the grass blades. Your mower blade level / height should be between 3 ½ to 4 inches for St. Augustine and 2 ½ - 3 inches for Zoysia in areas where any of the aforementioned weed types were or still are present in your lawn. The taller growing St. Augustine and Zoysia grass will eventually shade the invasive weeds, such as Bermuda grass, which thrives best in the sunny and dry conditions.
Here are some steps you can take at home to help eliminate and prevent home invaders
Even though there's no indication of termites in your home, only a thorough termite inspection by a trained professional can determine if they are present. Termites can squeeze through gaps as narrow as 1/32 of an inch to get into your harm.
Those "Ants" Might be Termites
Winged termites are often mistaken for ants. Here's how to tell them apart:
Winged ants have two pairs of wings and the front pair is larger than the hind pair; bot pairs of termite wings will be the same shape and size.
