Frogs...no problem, Fire Ants like wise, but this.

diatomaceaous earth is good (and should kill semi-slugs too) but as you have a young child, don't apply it anywhere he can go.

I knew a woman whose pre-school kid inhaled some of it and he was hospitalized and almost died. The same sharpness that kills the bugs will slice up human lungs, so be very careful about applying it.
