How they get in: Frogs often slip in through small cracks in vent pipes or drains, eventually hopping their way to the toilet.

Prevention: Cover vent pipes with fine mesh screens and seal foundation gaps.

3. Snakes

How they get in: Some snakes follow the trail of prey like rats or frogs and end up inside toilets through plumbing lines.

Prevention: Snake-proof your vent stacks with mesh and keep outdoor vegetation trimmed.

4. Cockroaches

How they get in: Roaches can squeeze through tiny gaps and enter toilets through drainpipes, especially in older homes.

Prevention: Seal cracks around pipes, keep drains clean, and use drain stoppers when not in use.

5. Lizards

How they get in: Small lizards can enter through vent pipes or cracks in sewer connections, especially in warmer climates.

Prevention: Install mesh covers on outdoor vents and reduce indoor insect populations (their food source).

6. Spiders

How they get in: While they don’t typically crawl up sewer pipes, spiders can sneak into bathrooms through floor drains or gaps and hide in toilets.

Prevention: Regularly clean bathroom drains and apply silicone caulking to seal openings.

7. Crabs (in coastal areas)

How they get in: In rare cases near the coast, small crabs can crawl into drainage systems and end up in toilets.

Prevention: Use fine mesh drain covers and ensure sewage pipes are properly sealed.
