The girls decided to solve our ant problem yesterday. I was skeptical when they asked for play dough, but it seems to have sealed the entrance quite nicely. Now it's a matter of finding a permanent fix - maybe something a little less pink.
Hubby and the boys put together a sandbox today. Now my cornmeal, flour, sugar, and all other fine, powdery substances can actually be used for cooking again. (As opposed to a playground for trucks).
