form large colonies that can number in the millions, enabling them to
outcompete native species for resources. Their diet is omnivorous, consuming
everything from sugary substances to small insects. Yellow crazy ants are also
known for their ability to produce formic acid, which they can use defensively

invasive nature, yellow crazy ants can negatively impact local ecosystems,
displacing native wildlife and altering habitats. Effective management and
control measures are crucial to mitigating their impact in invaded region
