The answer to 'signs of fire ant' is that the most common signs of fire ants include small mounds of soil in your yard, often with a hole in the center, as well as seeing the ants themselves. Fire ants are reddish-brown in color and typically build nests in open, sunny areas like lawns, gardens, and around structures. They are aggressive and will sting when their nest is disturbed.
If you notice fire ant activity, it's important to act quickly to eliminate the infestation before it spreads. For small infestations, you may be able to treat the mounds yourself using fire ant-specific baits or insecticides. However, for larger or more widespread problems, it's best to call in a professional pest control technician who can properly identify the issue and implement a comprehensive treatment plan.
