Seattle, Washington – After weeks of heavy storms and widespread flooding across parts of Washington state, public health officials are warning residents about an unusual but alarming post-storm risk: rats entering homes through toilets.
The Seattle and King County public health department issued the warning in a social media advisory, explaining that intense rainfall and flooding can disrupt underground sewer systems and force rodents into unexpected places inside homes.
Floodwaters Can Drive Rats Into Sewer Systems
According to health officials, heavy rain and flooding can sweep rats into sewer lines, where they may survive and move through the system.
“The heavy rain and floodwaters may sweep rodents into the sewer systems,” the department said, noting that rats are strong swimmers and can navigate plumbing pipes. Once inside, they may follow food or grease odors and emerge through household toilets.
While such incidents remain rare, officials stress that residents should be aware so they can respond calmly and safely if it happens.
What To Do If You See a Rat in Your Toilet
Health officials urge residents who encounter a rat in their toilet to close the lid immediately and shut the bathroom door to prevent the animal from escaping into the home.
After securing the area, residents are advised to take one of the following actions:
- Try flushing the rat back down: Officials recommend adding dish soap to the toilet bowl, which can make the surface slippery and help push the rat back into the sewer when flushing. Multiple flushes may be necessary.
- Call for professional help: If flushing does not work, residents should contact a licensed pest control company. Officials also recommend calling Public Health at 206-263-9566 or visiting the county’s rat control resources page. In some cases, a plumber may be needed to inspect sewer connections and toilet seals.
Officials Emphasize Prevention and Awareness
Public health officials say sightings are uncommon, but storm-related sewer disruptions increase the chances temporarily. They emphasize that awareness helps prevent panic and allows residents to act quickly and safely.
Inspecting sewer lines, avoiding grease buildup in drains, and ensuring toilets and plumbing connections are properly sealed can reduce the risk of rodents entering homes during extreme weather events.
Storm Impacts Extend Beyond Flooding
The warning highlights how severe weather can create secondary public health concerns beyond visible flooding damage. As storms become more intense and frequent, officials encourage residents to stay informed about lesser-known risks tied to infrastructure strain and changing environmental conditions.
Health officials say they will continue monitoring reports and advising residents as recovery efforts from recent storms continue across the region.
