"Swarming Ant Effect" - How?

[Domokun]

How would I go about recreating this or a similar effect? I know I'd need to spawn the particles and have them follow some sort of path. I am wondering about the back and forth movement and almost like a seek, collide/acknowledge behaviour and the "ant" spawning in different places.

What I usually do in similar scenarios,  is creating inversed spherical wind, so it attracts particles, and then I animate wind movement. 
Other then that you will probably need object bind operator (so ants are stuck to the ground), shape operator with animation on (so ants are animated), rotation operator so they are rotating in the direction of travel, particle physics operator, so they collide with each other, and finally some turbulence applied in the force operator, so they go more random (creating swirling patterns).

Thank you so much for your help/suggestion. I am attaching a video of what I have so far. I am unfamiliar with the inversed spherical wind. Is this the standard Max wind with - values or a Tyflow operator?
Right now my particles get spawned in one area of the object (seen at beginning of video) I'd love for them to be more spread  out initially. I have tried to use FACE or VERTEX in the object bind to no avail. Finally are there any nodes I'm using here that are redundant ?
Thank you again for your help.
