Little did I know that the volcano of dirt under some shrubs and extending into my lawn was from the same critters. I just kicked the dirt back and eventually the mound didn't grow any larger. I knew they were ants but not these guys.
Then there's the issue of a number of my plants not doing so well but I thought it was due to previous neglect, lack of water and I'm new to this climate. Maye some plants were going dormant for the winter.
So two days ago I was working in the garden and noticed the line of ants carrying parts of leaves much bigger than themselves. I followed them back home and sure enough it was where they had been pushing dirt into the lawn a few months before, yikes!!
All I have is a powder that I used on termites down in Melaque so I don't know if that will eliminate these or not. I found the following in an article on Yucatan Living. We'll see in the next few days.
The ultimate solution is pictured here. It is often called padrón by the locals, but this particular brand is called Extermirex. Only use it if you can find the entrance to the colony. Then, while wearing rubber gloves, pour the granules into any holes the ants are using and cover with dirt. The entire colony will be dead within five days. It is the most effective solution we’ve found.
Two openings to the nest with ant powder

An undisturbed nest entrance
So they don't like Bouganvilla eh?
Box shrubs are not immune
