They've ate stranger things....
I have a few suggestions, none are probably any good though.
1) set up some ant traps...............................................................................................................THIS IS THE EASY ROUTE OUT NO FUN !!!!!!!!!!!!!!!!!!!!!
2) get an anteater...................................................................GO WITH NUMBER 2 !!!!!!!!!!!!!!!!!!!!...........THIS WUD BE MY CHOICE
3) get a lot of magnifying glasses and fry the little bastards..........................................................YOU CUD MAKE THIS A EPIC BATTLE ON FILM !!!!!!!!!!!!!!!!!!!!!!
I wish I had a solution for you, I did my best.....
btw, I think you should get the anteater, I can see the most fun out of that option.
