I moved to Tampa and I am trying to figure out what these mounds of grey dirt on my lawn are and how to solve.
Answers:
Ah, the Fire Ant. It makes mounds everywhere it digs. Get some lawn spreader products from Lowes or Home Depot. The products say Fire Ant on them, and they work for one season. Your neighbor will get the ants after you use this stuff, and if you quit using it, the ants will come back.
Careful not to step on the hills in the daylight! They bite really bad.

Could be moles, but more likely fire ant hills (don't walk around them in open toed shoes!--and that goes for the rest of FL--ALWAYS be aware of what's around your feet, cause those little buggers are NASTY!).
You can get some ant poison from Lowe's or Home Depot. I forget the brand name. This site also also has some ideas from someone who sounds like they know what they're talking about:
How do you know when it time to pick a lime from a tree?
