One of the most invasive pests you can ever encounter is the fire ant. This type of ant is often lured near homes through surrounding plants, potted or not. They would want to invade your home when they detect fatty or oily foods.

They're those reddish-brown ants that have probably stung you one time or another. That's how common they are that for sure!

Fire ants got their name from the burning sensation that you feel when they sting you with their venom. Lucky you if you got away with it with just an itchy feeling. Some who have an allergy to insect bites would experience worse symptoms such as difficulty in breathing, swelling of the throat, and rapid heart rate.

When you see fire ants, avoid them at all costs. Get rid of them ASAP for your own good and to prevent further damage to your plants and home.

The good news is that it is quite easy to spot the habitat of fire ants. Just look for a mound. As fire ants dig underground for their nests, they push the soil upwards creating these mounds.

But this isn't where they live. They live deep under the ground and sometimes there are no mounds. You just need to observe and look for their presence.

Settling deep in the soil is one of their ways also to escape from human intervention. However, when the ground itself is hot and humid, you will see these fire ants making their way above the ground and that's when it's easy to spot them even without the presence of mounds.
