Ants invasion in Costa Rica

[Kailas]

Hi, we're visiting Costa Rica for a month and just got to our airbnb. In the evening, these ants started coming in and were everywhere, on the floors, walls, etc. Any idea what kind of ant these are?

Size: about 13mm and 10mm (specific ants from picture)
When: evening, around 9pm local time.
Where: inside the house in a jungle area, near the beach.
Appearance: red/amber with black bands on the abdomen
Behaviour: Some stationary on the wall for long periods of time. Others were exploring the area. They are quite fast when disturbed. Smaller one is incredibly fast.
Picture(s): https://imgur.com/a/bNAHxXc
Additionally: there appear to be 2 different sizes of them. One a bit smaller and thinner, and another a bit larger.

Thanks for your help!

That is Camponotus, but I am not sure about the species.

This morning, they are mostly all gone but a couple of interesting things to note. They left some dirt behind:

The locals call this ant 'arrieras'... Anyone know what that means? They say that the usually come in the winter months here and that they are considered good luck...

To elaborate on my last question about "arrieras", a search on google reveals that they are referring to leaf cutter ants... But these are obviously not that. So why call them arrieras?

Bring back turtle ants or Cephalotes spp.(Snap twigs to find them)

Also Atta cephalotes is in Costa rica too i believe

They'll be a bit more vibrantly colored
