Abstract: A biodegradable paper cover that temporarily blocks the “eye” of a motion sensor on an automatic toilet providing complete flush control to the user: Motion sensor toilets often flush when it is not desirable, such as when a person is on it. This is especially true for young children because their stature does not block the sensor consistently. According to research, the unexpected flush is one of children's biggest fears. This can lead to refusal to use the toilet, high anxiety, or annoyance for any aged person. The blocker is placed over the “eye” to temporarily disable the automatic flush of the toilet. When the blocker is removed the toilet returns to normal functioning and flushes. The blocker is disposed of in the toilet where it dissolves. It eliminates the untimely flush, as well as the potential transfer of germs. The blocker provides complete flush control to the user.
