I live in central FL. how do you get rid of ground moles?

If you have moles you have grub. Apply a grub control first.

Castor oil! It makes their food (could be grubs, or an bugs) taste bad, and they move on. There are garden products, both granular and liquid, that you apply and then water down heavily so it soaks into the soil. I've used both liquid and granular, and find the granular easier, but more costly. Both eliminated the problem in a few days. Best time to apply is right before you expect rain, you don't have to use as much water and let mother nature to the heavy work!

Mole Not worked for me many yrs. ago. Call Ace Hardware, Home Depot or Lowes and see if it is still manufactured.

I use these twirling lawn ornaments , when the wind blows it spins and vibrates the ground and they hate the noise and they move on

Gopher snake and they do good in Florida.
