Where Do Roaches Come from in the Bathroom?

These days, cockroaches seem to come from everywhere, especially if you are dealing with an infestation. Though one of the common places roaches appear are kitchens and pantries, with food left over as one of the things that attract them to your home.

However, you should know that there is no limit as to where roaches can appear. So in today’s post, I am going to answer the question a lot of ask as to where do roaches come from in the bathroom?

Why Do You See A Lot of Roaches in the Bathroom? 

Top Places Roaches Come From In The Bathroom

When it comes to roaches in the bathroom, they always come from the sewer, window frame, beneath the door, and cracks in the wall. For places like cracks in the wall, cockroaches lay eggs and it hatches, thereby leading to more roaches in the bathroom.

A lot of people think that insects are more common in the bathroom than other rooms in their house due to huge insect populations thriving in the sewer systems.

However, I have been able to observe roaches in the bathroom more frequently since they normally fall into sinks and bathtubs and find it hard to escape.

Note that roaches travel indoors because they seek food, water, and shelter, or the combination of the three. Meaning that any room in the house that has more water appliances like the kitchen, a basement with a plumbing system, or the bathroom may be more prone to attracting cockroaches than any other rooms in the house.

Like I said before, cockroaches are likely to fall into bathtubs, the shower, and kitchen sinks and won’t be able to escape. It simply means that you may see more cockroaches in your bathroom than any other room.

However, it doesn’t necessarily mean that there are more roaches in the bathroom than in other areas. So to answer the question of where do roaches come from in the bathroom, I will list and discuss the top places roaches come from.

Top Places Roaches Come From In The Bathroom

  • Under The Basin

Remember that water supply is one of the biggest reasons there are roaches in your home, so it shouldn’t surprise you if roaches appear from under the basin in your bathroom.

Since there are pipes supplying water to your house, which means there must be a small leak or gaps around the pipework that cockroaches use to gain access to your bathroom.

  • Under The Bath 

Similarly to the first point above, remember that under your bath has 2 major key things that roaches look for, they are:

  1. Entry gaps
  2. Water supply

Note that there is also the possibility of them feeling secure under your bath. This is because it is a good place for them to lay eggs faster.

  • Your Window Frame

Having gaps around your window frame gives roaches access into your home, and also offer a way out for them once they sense trouble coming. But not only that, any bathroom window may pick up condensation, which in turn offer roaches a drinking station.

  • Drains

Remember that in your bathroom, there are likely to drain running from your bath, basin, and shower,  and each of these will offer roach access to your home.

  • Around The Toilet Seat 

If you are among those asking, where do roaches come from in the bathroom? Then it is good you know that one of such places is the toilet.

Although cockroaches do not live in water, they can hold their breath for a long time. A time that is long enough to traverse your drain system and exit via your toilet.

Remember that your toilet is an entry point into your bathroom for any cockroach, and it also offers them a perfect drinking station.

Making use of both items will terminate cockroaches inside the pipework, and will act to deter them for a short time. Once you do this, as you pour water into the pipes, the scent of the deterrent will just disperse and will no longer be effective.

Once you have observed that roaches are coming up through the pipes, then try to use the plug or buying a cover for the drain hole in your basin, bath, or shower.

Try Fixing Any Leaks

Fixing any leak is the biggest and best thing that you can do to prevent roaches from getting into your bathroom.
