If you are wondering why bugs and other pests pay your bathroom a visit, it’s because of all the moisture. And when we’re talking about the toilet seat, in particular, many people fail to clean it consistently and in detail. Flushing isn’t enough, since there is the residue left behind and that is enough to attract all the wrong guests.

Bright Side wants you to know that many pests can crawl into your house through your toilet and that there are ways to prevent this from happening.

1. Snakes

Snakes just love cool, wet, and dark places and that’s why your toilet pipes can be very intriguing to them. But, what drives them there in the first place is the sewer that has food remnants that they can feed on. When they are finished with their food in the sewer, they will look for a way out and the pipes are the easiest and quickest route. However, you shouldn’t be afraid if you live in a cold environment, since snakes will only sneak up in toilets in warm countries.

It’s usually harmless snakes that crawl through the pipes, like garden or tree snakes. That’s because these snakes are slimmer than venomous ones and can fit through the pipes. Although, some anacondas have appeared in people’s toilets in South America and Australia.

2. Rats

Like snakes, rats are also in constant pursuit of food and our pipes can be very appealing to them. In houses where the toilet and garbage disposal end up in the same pipes, rats are more likely to find a way in. And because their anatomy is very bendy, they can swim through the pipes and hold their breath for minutes before they need air.

So, it’s not just important to discard your food remnants in a trash bag but to also never flush food down the toilet. If there is no food in the pipes, rats won’t have any reason to try and enter your sewage system. You should also keep the toilet cover closed at all times and maybe install a rat guard. This allows water to exit the pipes whenever you flush, but nothing can come up in the opposite direction.

3. Spiders

With spiders, things get a bit more complex, since they can’t swim in your pipes, but they can appear in your bathroom through another passage. And when they get in, they will probably sit outside the toilet seat. Only black widows will crawl inside the toilet and weave their web from side to side. But, that will happen only in an outdoor toilet that doesn’t have plumbing and that isn’t connected to a sewer system.

That’s where these venomous spiders thrive since there are many flies that they can catch for food. That’s also why you need to always check the seat thoroughly before using an outhouse toilet. Spiders, like the black widow, the brown recluse, and the hobo spider won’t have any trouble biting you.

4. Lizards

In the Southwest United States, lizards coming through the toilet pipes are a quite common occurrence. That’s because these creatures love water and they try to find food wherever they can. Crickets and other insects (like flies) can be found a lot in your toilet’s plumbing if it’s not kept decently clean. The lizards that can achieve this are usually small enough that they can fit through the pipes.

5. Possums

In 2008, a man was in his bathroom in Australia when he saw the water in the toilet gurgling. Moments later, a baby possum appeared and this is not the first time this has happened. On another occasion, a woman found a dead possum in her toilet. These unusual guests are excellent swimmers and can hold their breath for a long time — that’s why they can crawl into your toilet.
