Where do roaches come from in the bathroom
Roaches usually enter bathrooms through wastewater drains. Since drains are directly connected to the sewer system, and American Cockroaches, a.k.a palmetto bugs, are extensively found there, they find a way to pop up through the drain holes, even if they have to swim through the commode S trap. They can also come through another hole or a gap in walls, doors, windows, etc.
Generally, roaches keep wandering in search of an ideal environment with plenty of food, a lot of humidity, and ideal warmth.
Bathrooms are humid and warm but a little scarce of food, although the tissue paper laying around is not less than a healthy meal they are looking for.
A cockroach can also land in your bathroom from somewhere else, like your kitchen or room, but the drain theory is why you have it most of the time.
If the cockroach lays eggs inside your bathroom, you can spot small roaches in the bathroom which are most probably the baby roaches. So don’t panic after spotting tiny roaches in bathroom, as they are not going to be a different kind, just baby roaches.

Can cockroaches come up through toilet?
The American cockroaches live in the sewer system (source); they can rarely come up through toilet drain pipes.
Roaches are not natural swimmers, but they can survive underwater for many hours and move through it. So a roach can cross through the small amount of water in the water trap inside a toilet. However, if the toilet is wet, a cockroach will find it hard to climb up. If it’s dry, it will quickly climb up.
Cockroaches will come up through toilets more frequently with P-Traps. However, S-Traps are tricky for roaches to cross.
Found one cockroach in bathroom, should I be worried?
There are a lot of chances that the cockroach hiding in your bathroom is alone. Because a single cockroach does not mean there will be more. Although, this can be an early sign of an infestation.
Generally, if you find one cockroach in the bathroom, it will not cause any problems or cause an infestation. Although roaches can cause health problems because they crawl through trash and sewers filled with bacteria and germs. However, exposure to a single bug won’t possess too much of a health risk.
So, don’t panic. This little creature will be more afraid than you. Almost incapable of biting back or sting. And there are a ton of ways to get rid of it.
Roaches in bathroom at night
A cockroach won’t get into your bathroom at night and will leave in the morning. The roaches you see in your bathroom at night are still there in the daytime, except they are hidden.
Interesting Read: Can Roaches see in the Dark?
Cockroaches are Nocturnal and active at night. So, you should adequately investigate all hidden spots inside your bathroom to find any hidden roaches, as the roaches you see at night in your bathroom are the same already living inside your bathroom.
You should look under and behind the sink, inside all cabinets, hinges, drawer slides, etc. Look around everywhere and make sure there are no baby roaches in a bathtub or around. Learn more about where do roaches hide here.
How to get rid of cockroaches in bathroom?

Step 1: Kill the roaches with BAITS
Step 2: Close every possible way for roaches to sneak inside your bathroom

Let’s discuss all these spets in detail.
Step 1: Use a bait
The first step is to use bait to get rid of any roach inside your bathroom. Baits are better than sprays as baits will kill the entire colony.
You can get your hand on many baits, but these are my favorite ones. Use each of them according to instructions on the pack.
– Bengal Roach Killer is a dry spray bait, very easy to apply and use. (How to use guide)
– Advion Cockroach Gel Bait is the most effective gel you can buy.
– Hot Shot Liquid Cockroach Trapper and Killer is the best trap you can get for cockroaches.
– Combat Max 12 Month Roach Killing Bait is the best bait out on the market.
Step 2: Close all openings
The next step is closing all openings into your bathroom; else, it will be impossible to stop an infestation. Use Loctite Foam Sealent (Amazon Link) to close gaps and openings like a pro.
Step 3: Use an IGR
Using an IGR is the last step to ensure the roach nymphs don’t grow into adults. An IGR alters the internal hormones of roaches to molt. This way, the roaches can not become adults and reproduce. Gentrol Growth Regulator (Amazon Link) is the only and the best IGR device for roaches.
Its very easy to use. Just purge one of them and place it in a hidden place inside your bathroom.
Methods to spot the hidden palmetto bug in you bathroom
There can be multiple places where a palmetto bug can hide in your bathroom. However, you can trace it by utilizing a targeted approach.
Start from one side of the bathroom and make your way to the other side. Use your smartphone flashlight to have a better chance to find them.
Look carefully in and around cupboards, cabinets, sinks, showerheads, bathtubs, and toilets. Door hinges are a good spot to hide. Do make sure to turn around all cosmetics items, bottles, and perfumes on shelves. When looking around sinks and bathtubs, make sure to look from the underside to cover every aspect. A cockroach can easily hide beside bathtubs.
Don’t miss under the toilet reservoir and around water valves. Also, check exhaust vents & openings. Damaged tiles, flooring, and fixtures can also be an ideal hiding place.
Tapping your feet on the floor may help scare this little beast and give you a chance to spot it.
If you are smelling a musty smell, you may have an infestation, and the source of the smell can lead you to the hiding colony of the ONE roach you saw.

How to make sure it doesn’t come again?
Getting rid of cockroaches is challenging as they are incredibly prolific. Unfortunately, there is no absolute method of controlling the infestation of palmetto bugs as they can come from any source because of their attraction to warm, humid climates. But here are some methods that can be effective.
- Place metal meshes on all drain holes with small holes.
- Keep your bathroom dry. Keeping the exhaust fan turned on can help keep it dry.
- Repair all cracks and fictures in your bathroom.
- Place door seals between the gaps of the door so that no bug can crawl into your bathroom.
- Good clean-up and sanitation practices are essential to prevent infestation.
- Avoid accumulation of water behind all possible hiding places. Fix water leaks and cracks to remove moisture sources by checking the plumbing system.
