Hilarious game. Might be a bit tricky for most people at first.
The way to go is : Wipe out any enemy colonies next to you (if any).
Do this by increasing the number of soldiers relative to the other kinds. Breed breed breed, get a small army together and attack their nest. Your goal is to kill their queen. Don't fight it out, (you'll probably lose) get their queen instead. Then kill the rest of them.
As soon as you're safe. increase the number of flying ants to a high ratio and spread spread spread. Try to enclose the red menace. Once your colonies are in contact with the red zones increase your soldier ratio again. While you fight red to a standstill, wipingout the occasional colony, your ants will spread all over the rest of the map without opposition. Oh yeah, never let your worker ratio go lower as 40% and right at the start turn it up as high as 80% for rapid growth.
