Actually AJ did.  After much pestering from me (sorry!) he bought 2 boxes (4 chalks all) for us to try out.

I’ve drawn lines already in all our kitchen cabinets.  Tomorrow I will continue with the cupboards.  I think it’s better to do that in the morning so I could draw the lines better. 

So there.  I hope I won’t see creepy insects crawling in there anymore. 

No more shrieking episodes for me, please.
