A interesting trick?

I have to share this tip/trick or what may you call it. 
On a show last night,I believe Extra? Not sure
 They claim that..Get this...they claim that put a out line of chalk around where you think ants are coming in...will keep them out. 

So this mama,of a older style house and a hater of ants...TRIED IT. Yes I was the crazy lady in the window,outlining it with chalk, I was the crazy lady outside my house with my chalk...

Now I am not sure if it works yet so stay tuned to see my "review" but accoring to people. They just will not cross chalk.

My art work in my daughters room lol.
Stay tuned. And let me know if you know it works or not.
