Why You Shouldn’t Flush Spiders Down the Toilet—The Hidden Consequences

Many people think flushing spiders down the toilet will make them drown and kill them but that is not true. Spiders can live up to 4 or 5 days submerged in water and if not properly killed when flushing them down the toilet they could crawl back up the drains where you sent them down. Imagine sitting down on the toilet thinking everything is alright just to be bitten where the sun don't shine. Flushing spiders is inhumane, harmful to sewer systems, and often ineffective.

Spiders may seem like fleeting nuisances, but choosing to flush them down the toilet can lead to harmful consequences—for both the spider and your plumbing. While many households default to the flush method, this seemingly quick fix is often ineffective, potentially inhumane, and can even cause plumbing issues.Contrary to popular belief, spiders aren’t always killed instantly by the flush. Many species are remarkably resilient—some can trap air bubbles around their bodies or slow their metabolism to survive submerged for significant periods, sometimes up to 30 minutes or more. Even if they drown, their journey through the U-bend, pipes, and sewage systems remains fraught. Learn safer, eco-friendly alternatives for handling unwanted eight‑legged visitors.
