Imagine you are walking through a forest and all you can hear is the rustling of trees. The forest is silent and no native animal or critter can be seen, they are gone. The ants have destroyed the natural environment. You look down and the ground is moving, carpeted by hundreds of thousands of yellow ants. The ants move erratically and they’re heading for your feet, more and more ants follow and crawl up your leg so you run, hoping the ants won’t fall from the trees. You run out of the forest with great relief and the forest is silent once again.
That is the impact of yellow crazy ants once they are established in an ecosystem, which is why we need to eradicate them.
