M.H.
Ant traps are WONDERFUL!!! We get ants in our kitchen every year and these little babies are perfect. Unless your child puts everthing in his/her mouth I wouldn't be worried because they are virtually impossible to break, and the will get all of them in about a day (and keep them from coming back). You could also use an ant spray, but I would keep your family away from that area for a period of time just to be safe.
