Getting Rid of Tiny Bugs in Bathrooms: The Quick Answer

If you’re looking to get rid of tiny bugs in the bathroom, you should set up a bug trap or bait as soon as possible and try to fill in any open cracks or crevices to keep new bugs from coming in.

You should also aim to keep your bathroom a bit more clean, as tiny bugs like to thrive in damp, dark places.

If you’re looking to prevent tiny bugs from taking over your bathroom in the first place, make sure you keep your drain and sink clean and keep your bathroom moisture level low, which can attract pests.

How to Get Rid of Tiny Bugs in the Bathroom

Depending on the type of bug, level of the infestation, and location where you’ve found them, there are a few different ways you can troubleshoot the issue of tiny bugs infesting your bathroom.

Use these troubleshooting tips to solve the problem and keep them from coming back again.

1. Keep Your Pipes and Sinks Clean

The first thing you should do to create an environment that is hostile to tiny bugs in the bathroom is clean out your pipes and sinks. 

Both shower and sink pipes as well as the sink itself are hot spots for holding onto sticky and gross things like spit, toothpaste, products, and mold. Bugs are attracted to the smell and will often flock to the shower or tub drain or the bottom of the sink. 

If you’re seeing bugs around these areas, it may also mean that they are coming in through these pipes.

If possible, turn your water off and take out your sink plumbing and give it a good clean-out. You may also want to clean out your shower drain by snaking it with an old wire hanger or drain unclogging tool, as bugs may be coming up and inside through here.

2. Deep Clean Once a Month

Another strategy to get bugs out and keep them out of the bathroom is deep cleaning the space at least once a month. It’s easy to get into a basic cleaning routine and neglect some of the more hidden parts of the bathroom, but these areas can be exactly where the bugs thrive.

In addition to your basic bathroom clean, you should also wipe down all surfaces from ceiling to floor, including the corners and crevices where moisture and bathroom products tend to accumulate, like the base of the sink, grout lines in the tile, and even baseboards.

You may also want to incorporate a monthly pipe cleaning if the bugs are a recurring issue. Deep cleaning will also allow you to find any bugs (or dead bugs) that might be hiding out so you can slowly eliminate their presence.

3. Use a Bug Trap

If you’re having trouble catching the bugs that are in your bathroom currently, save your energy and time and get a high-quality bug trap that can do the work for you while you handle your other tasks. 

You may want to get a few depending on the size of your bathroom. Place them near the areas where you think the bugs are getting in as well as near where they are congregating for best results.

4. Empty the Trash Regularly

Bugs thrive on dirt, and many, like silverfish, also like to eat paper. Keeping your trash cleaned out is a good way to prevent them from making a home in your trash or near it in your bathroom.

Don’t put any wet items in the trash can, either, as this extra humidity is the perfect way to attract more pests and give them a comfortable place to hide.

5. Reduce Bathroom Moisture

Reducing the overall moisture in your bathroom can be an effective tool to eliminate bugs from your bathroom, as they thrive on wet, damp spaces. You can get a dehumidifier as a good start or add a fan to your bathroom if you don’t have one already.

6. Fill in Cracks and Crevices

If you have any open cracks, crevices, or gaps in your bathroom, these could be the sneaky locations these tiny bugs are hiding or even how they’re getting in.

Eliminate these areas as possible entryways by filing them with grout or sealer, and you’ll never have to worry about them sneaking back in this way again.

Things to Consider

Before you get to your pest control, there are a few things you should consider to understand what kinds of bugs you’re dealing with and how they got there in the first place.

Common Bathroom Pests

The most common types of tiny bugs you’ll find in the bathroom include:

  • Roaches – The classic cockroach, can be small or large, a dark brown to black color, can carry disease with them
  • Silverfish – Small, long, silver, flat bugs that tend to congregate near sinks, toilets, wet spaces, or spaces with paper
  • Drain flies – Small, fuzzy-looking flies that flock to shower and sink drains
  • Gnats – Tiny black flying bugs that often travel in groups

How They Get Into the Bathroom

Next, you need to consider how these bugs have gotten into your bathroom.

Are they coming in through the drain of your shower or sink?

Are they creeping in through an open window that doesn’t shut all the way?

What about cracks in the baseboards or tiles?

Being able to identify where they’re coming from will help you cut off this entryway as a possibility and prevent more bugs from coming in this same way.

You may need to clean a drain, patch a hole, and re-grout some time, but they’re all pretty quick and easy fixes.

Frequently Asked Questions

Learn more about how to deal with tiny bugs in the bathroom through frequently asked questions.

How do you know if you have tiny black bugs in the bathroom?

You’ll know you have tiny black bugs in the bathroom because you’ll either see them or their dead bodies lying around your bathroom, often in areas close to the bath or shower drain as well as the sink.

What are the most common tiny black bugs in the bathroom?

Is there a natural way to get tiny black bugs out of the bathroom?

While bait traps and pest control sprays can be effective, simply removing the bugs, eliminating their path of entry, and making the bathroom a hostile environment for them by keeping it clean and removing humidity is the best way to get rid of tiny black bugs in the bathroom naturally.

What are the risks of tiny bugs in the bathroom?

There are some associated risks with the presence of these tiny bugs in the bathroom. Cockroaches, for example, are known to carry diseases with them, such as giardia, typhoid fever, cholera, staphylococcus, as well as other bacterias, funguses, molds, viruses, amoebas, and parasites. 

If not removed from the area and you come into contact with one of these bugs or touch an area where the roach has been, there’s a risk of contracting these diseases and illnesses.

Silverfish can also cause allergic reactions among many, so you want to keep these pesky bugs out of your bathroom entirely if possible. While the risks from these bugs aren’t high, it’s still there, and the best way to eliminate the risk is to eliminate the presence of the bugs.

Where do tiny bugs in the bathroom hide?

Another thing to consider is where these bugs are hiding out in your bathroom. Finding bugs in the trash with toilet paper and other paper products, for example, might help you to identify the bugs as silverfish since these bugs like to eat paper.

Knowing where they hide also gives you more opportunity to kill them or remove them from the bathroom as you see them since you’ll always know where to look.
