Wet weather creates temporary pools, wet surfaces, and new paths for small and medium-sized wildlife. Frogs naturally seek calm, shallow water where their eggs can develop safely.
If a bathroom has an uncovered drain, a nearby open vent, a window crack, or other access point, frogs may accidentally enter the area while seeking moisture.
Once eggs are laid in stagnant water, they can hatch into tadpoles. Because toilets contain water and often remain undisturbed for periods of time, they can temporarily resemble a small pond.
Are they dangerous?
