Rats are remarkably versatile and resourceful creatures. One surprising aspect of their behavior is their ability to swim and access toilets. This unique adaptation can be both alarming and startling for homeowners. Rats are strong swimmers, capable of treading water for up to three days. They can enter plumbing systems through sewer lines, swimming up pipes, and into toilets or drains. This ability to infiltrate homes through the sewage system is a potential health hazard, as rats carry diseases and can contaminate water sources. To prevent rat invasions via toilets, homeowners should ensure their plumbing systems are properly sealed and regularly maintained. Installing sewer guards and keeping toilet lids closed when not in use can also help lessen the risk. Rat-proofing plumbing is a crucial step in safeguarding against these resourceful rodents’ unwelcome visits.
