No, not really. Pico de gallo is a mild salsa. It will depend on how spicy your jalapeños are. If you happen to get a really spicy one you can tone down the heat by rinsing the sliced pepper under cold water and discarding seeds as well as the white inner veins or "pith". If you'd like your pico to be spicier you can add as much jalapeño as you like. I would also suggest throwing in some of the seeds which pack quite a bit of heat!
