How to make ants vanish?

They're everywhere!! I'd burn down their ant hill, but they're all under trees.
They crawl all over our patio and sidewalk ; they keep us from sitting outside and enjoying the birds. Oh! And these stupid red-headed ants are taking over a few of our...

favorite trees and (oddly) supporting these aphids. Funny how the ants will bite and eat anything in their way except these dumb aphids which are bad for the trees!

Help! Is there anything that would rid these ants that are taking over??

Thanks!

Spray some bug repelent stuff on it. just make sure its not bad for the tree!

AMDRO, ORTHO Max, or D.E. (if you don't like using pesticides)

Go to walmart or some store and get some bug repellant it works, but if you have kids or animals make sure there not around most bug repellants are poisonous! Good Luck!

THATS A GREEEAAT IDEA!!!

Ok, I'm going to go outside and Stomp on 1 Million Ants.
