We have those Caribbean Crazy Ants too. They scatter all over the patio like ‘crazy’! They are an invasive species from the islands in the Caribbean and came her on fruit most likely. They don’t bother me much because they will actually drive off Fire Ants.
These so-called ‘Sugar Ants’ are so small that they can barely be seen. I’ve never seen them anywhere else. We spray along the base boards and the door sills and the foundation, but they eventually come back from somewhere..........
I looked up the Caribbean Crazy Ants ... those are too big for the ones we have had.
The ones we have/had are super tiny, black, and don’t march in lines ... they’re in more of a scattered pattern.
