This guide is helpful for you, here you can find five baby bugs in shower grout that are make your bathroom infested. You’ll learn what causes these bugs in shower grouts and bathroom floors, where they come from, and how to get rid of them.

It is common for cracks to form on bathroom floors, tiles, and shower grout due to high humidity.

Cracks serve as breeding and feeding grounds for many tiny bugs.

Why Do You See Bugs On Shower Grout?

Honestly, let’s face it. Moisture and dampness attract bugs. You’re probably using the bathroom quite a bit. 

Weak grout in the shower is caused by dampness. Cracks form in the shower grout. There are different types of waste that get stuck in these cracks, including hair, foam, and nails.

As a result, sludge and molds form. These tiny bugs feed on slime and mold, which you’ll discover in a moment.

As time passes, these gaps widen. These gaps provide a perfect hiding place for many bugs.

Additionally, clogged drains play a role in attracting these bugs. Clogged drains are breeding grounds for a particular flying bug about which we’ll talk in a moment. 

The worst part?

You don’t have to worry about these bugs in your bathroom. 

They multiply quickly. If you fail to act quickly, these bugs will spread throughout your home in no time.

However, excessive dampness inside your home is where it all starts.

Kitchens, basements, bathrooms, and laundry rooms that are damp and have drains are where infestations start. 

Another thing that plays a significant role in keeping these bugs thriving.

As a result of excessive water, mold forms on the shower grout and on the walls and floors of the bathroom.

Mold is the food source for these tiny insects.

Fortunately, none of these tiny bugs in the shower grout are harmful. They also do not bite.

There are many ways for these bugs to enter homes and bathrooms.

Your yard provides some of them. Some of them can latch on to items you bring inside.

Those that fly can also get inside your home if your neighborhood’s drainage system isn’t up to snuff.

So, what are these tiny bugs in the shower grout?

Let’s find them out.

5 Baby Bugs In Shower Grout That Spread Fast

  1. Psocids mites 
  2. Mold mites
  3. Drain flies or sewer flies
  4. Silverfish
  5. Worms

Let’s find out what these bugs are and how they land up in the shower grout and bathroom. 

Shower grout and bathroom floor infested with psocids

Mites known as psocids feed on mold that grows on wet surfaces such as shower grout and bathroom floors.

The mites, also referred to as grout mites, are common in poorly maintained bathrooms with water leaks.

Your bathroom is not the only place where they live. The presence of Psocids mites in your home can occur anywhere that has dampness and mold growth. 

So, places like the kitchen, basement, and laundry room are where you’ll find them most often. 

From stored grains like rice to books, psocid mites infest a wide range of materials. 

A booklice or paper mite is one of the species of psocids that infest books.

Psocids mites appear as tiny brownish-gray bugs on the shower grout and the bathroom floor.

Up to half a millimeter long, they grow. There are some that are even smaller. 

Psocid mites have six legs and thick hind legs. If you examine them under a magnifying glass, you’ll see they look like termites. 

The psocid mites have a well-developed mouth that allows them to scrape away molds and fungi from the shower grout. Despite this, humans are not at risk of being bitten by them. 

You can find these tiny mites outside your home. Mites are always looking for damp places to live and breed. 

Psocid mites seek out new food sources and shelter when the weather becomes dry outside, or when their numbers increase.

During that time, they move into the house through thin gaps and cracks in the windows and doors.

It is also possible for them to enter homes by latching onto things like cardboard boxes or plant pots you bring into your house. 

The Psocids mites reproduce quickly, and if you don’t eliminate them, their numbers will explode. 

The larvae of the psocids mite take ten days to become adults.

Mold Mites On Shower Grout 

Mold mites are tiny white bugs that feed on mold that grows on damp surfaces. Some mold mites are brownish in color.

Their size grows only up to 0.03 mm. Mold mites are also common in the grouts on bathroom floors, just like psocids mites.

The mold mites have bristles on their bodies. They use the bristles as sensory receptors to detect mates and food sources.

Mold mites don’t limit themselves to eating molds when it comes to feeding. They are also a problem in pantry cupboards.

Food stored in jars and containers in your kitchen pantry will be invaded. 

Mold mites damage food, which emits a foul smell. The food also appears dull and stale.

Mold mites are difficult to see with the naked eye. Apart from being microscopic bugs, they’re also transparent white and blend well with shower grout.

As a result, it may be difficult to detect them when they’re few in number. However, as they grow in numbers, their presence becomes noticeable in the form of discoloration on surfaces infested by them.

Mite dust, also referred to as white dust, forms on surfaces infested with mold mites.

As they grow across the gaps between the tiles, grout mold mites appear as whitish brown patches.

Humans cannot be bitten by these mites. As with dust mites, mold mites can also trigger allergic reactions in some people, especially in the elderly and young.

As a result of their hairy bristles, they cause allergic symptoms.

A mold mite’s hairy bristles can cause itching and reddish welts when they crawl onto your skin.

Mites like these spread quickly. An egg takes less than three weeks to mature into a mature mold mite ready to reproduce.

An adult female mold mite can lay 300-400 eggs in her lifetime. Mold mites live between 10 and 30 days.

Any object that is damp can be infested by mold mites, including books and furniture.

As well as wood mites, these mites live on the wood.

Bathroom floor tiles and shower grout infested with drain flies

Do you have fuzzy moth-like bugs on the bathroom floor? Those are drain flies.

On the bathroom floor, drain flies will look like tiny black specks. However, when touched, these tiny black bugs will fly away.

In your bathroom and throughout your home, drain flies mean you have clogged drains

The waste stuck in the shower grout attracts drain flies. If there are molds, they will eat them as well.

Drain flies may even lay their eggs in the cracks of the bathroom floor and on the grouting.

Despite having wings, drain flies are weak fliers, unlike house flies and fruit flies.

They can’t fly in one direction. So, drain flies jump from one place to another in an erratic fashion. 

Many people confuse drain flies with springtails in the bathroom, but springtails are larger. They also have different shapes.

On top of that springtails are jumping bugs in your bathroom. As drain flies jump too, so many people can confuse springtails with drain flies.

The most common cause of drain flies in the bathroom and home is choked drains.

Your home will be infested with drain flies from the outdoors if you have open doors or windows.

You will find drain flies laying eggs in the wastes that clog your drains inside your home.

Those wastes are wet, so drain flies can lay their eggs there.

Larvae from the eggs feed on the scum that develops on the inside of drains.

When the larvae grow into adults, they emerge from the drain holes. The reason you see adult drain flies near drain holes in sinks, bathtubs, and toilets is because of this.

As drain flies are dampness-seeking insects, they can also get inside electrical appliances such as dishwashers and refrigerators. 

The sight of dead drain flies and gnats inside the fridge is not uncommon when the house has a massive drain fly infestation.

They spread quickly. Drain flies soon become an irritating nuisance within your home if you don’t get rid of them.

But drain flies are harmless. They don’t bite.

However, they feed on the most unhygienic wastes such as food wastes and sewers.

The pathogens from these places remain on their bodies. Drain flies transmit these pathogens to food they sit on.

Infections caused by these pathogens make humans ill. Getting rid of drain flies and their sources is crucial.

Silverfish In Bathroom Grout

Silverfish eat dampness when the weather outdoors becomes too hot and dry for them. Silverfish enter homes to find dampness when the weather is too hot and dry outside. 

The silverfish in the bathroom are tiny, wingless black bugs

Silverfish are nocturnal creatures. So, they perform their feeding activity during the night.

Your bathroom has dark gaps and corners where silverfish hide during the day.

The silverfish feed on dead insects, molds, organic wastes like hair and nails, and sludge that accumulates in the shower grout.

They can even hide in cracks in the shower grout if they are wide enough. 

Molds and fungi thrive on damp surfaces. Molds can grow on anything that develops molds, including books and paper.

Silverfish have silvery scales on their bodies and are tiny silvery bugs. Their appearance is similar to that of shrimp. A pair of antennae are on their heads and they have two appendages at the back of their bodies.

The heads of these animals are larger than the abdomens. These are thin, long, thin bugs that you can find in your home.

Additionally to mold, silverfish will eat stored dry foods such as grains and cereals, fabrics, paper, sugary stuff, and things high in starch and protein.

They can also be found in your kitchen pantry.

The kitchen is also a perfect place for them to infest. In the kitchen, there is both stored food and dampness that silverfish need to thrive and multiply.

Despite this, they do not cause a lot of damage. 

The silverfish do not bite humans. They also don’t spread any diseases to humans and pets.

Worms On The Bathroom Grout

Nowadays, there are no specific worms that infest bathrooms and shower grouts. Infesting bathrooms and homes are these worms, larvae of flies and beetles.

Your bathroom floor and shower grout can serve as an egg-laying ground for many types of bugs such as weevils, beetles, and drain flies.

Once their eggs hatch, the larvae venture out in search of food. 

There can be various reasons for this, such as when the larvae do not have enough food or the adults have not laid eggs on their food source.

As a result, you will see larvae crawling on the shower grouts, bathroom floor, bathtub, and even bathroom sinks.

The worms that you see in your bathroom and home are probably drain fly larvae if there are drain flies present.

These worms are brownish or blackish, and they crawl slowly on the bathroom tiles and grout. They feed on the scum sticking in the thin crevices of the grout and tiles.

Maggots can also be these worms, which are larvae of house flies. You can also find house fly eggs in cracks and gaps inside your home. In addition, they won’t miss out on your bathroom if there are enough gaps there.

How Can You Get Rid Of Tiny Bugs In The Shower Grout?

Bugs in the shower grout and bathroom floor are part of a larger problem in your home. The cause is excessive moisture. 

All your efforts will be for nothing if you do not fix the dampness in your home and bathroom.

Now let’s take a look at the five steps to getting rid of tiny bugs from the shower grout and bathroom floor.

Step#1 – Repair Leaking Pipes

Leaking pipes are one of the reasons for high dampness in the bathroom floor, walls, and even in your house.

The constant dripping of water from leaky pipes in your plumbing area increases the dampness in the structure of your home. 

Bugs are attracted to dampness, as you know. 

Make sure that there are no water leaks under the sinks, faucets, and in the plumbing area of your bathroom.

Home foundation leakages and dampness in areas like the kitchen and basement also contribute to overall dampness inside homes.

Fix any errors you find. It’s best to hire a plumber if you can’t fix the leak yourself.

Step#2 – Clean And Unclog The Drains

Drain flies are attracted to clogged or choked drains, as you probably already know. Drains clogged with debris are not only breeding grounds for drain flies, but also roaches.

You often see baby roaches crawling from the bathroom and kitchen sink drains because of that.

Using a drain cleaner will help you clean the drains. Alternatively, you can pour a mixture of boric acid (or borax) and hot water down the drains.

A mixture of white vinegar and hot water will also work.

It will kill any drain fly eggs, larvae, and even roaches hiding in the drains.

If the drain clogging is severe, as it usually is when bathrooms with clogged drains are left unattended for weeks and months, pour a solution of bleach and hot water down the drains.

Bleach is a lethal pesticide. It should not be used more than once. Irradiation with bleach can cause serious damage. When drainpipes are overused with bleach, they may become damaged.

No matter what you pour into the drains, always use a drain plug to close the drains of the bathroom floor, sink, and bathtub.

That will stop the larvae and adults of drain flies from emerging through the drain holes.

Unclogged drains are essential for allowing water to flow. The wastes that clog drains are not only breeding grounds for drain flies, but also for mosquitoes.

Step#3 – Seal the Gaps And Cracks On The Grouts And The Tiles

Grout gaps and cracks that develop over time hold a lot of debris that these bugs eat.

Make sure the crevices are sealed. Seal these cracks with silicone-based sealants. The silicone-based sealants are strong, waterproof, and they last for a long time.

What’s the best part? Silicone sealants can’t be chewed through by bugs.

There are loose floor tiles with broken grout between the tiles that need to be repaired.

Bugs like centipedes can hide in cracks and gaps in the bathroom floor when these cracks and gaps become wider. 

You should also seal the cracks in the bathroom windows. 

Cracks can serve as entry points for flies which are attracted by dampness.

Install window screens on the windows as well. This will keep the bugs out of your bathroom and house.

Step#4 – Get Rid Of Molds In the Bathroom Using Bleach

Mold must be removed from the entire bathroom and home, not just from the shower grouts.

What’s the reason?

It’s because molds provide food for many of these insects. It’s easy to get rid of these tiny bugs when there is no food supply for them. 

Mold can be difficult to remove. It will take professional help to do the job, especially if there is a large amount of mold growth. 

However, you can do your part to get rid of these molds.

The bleach and water should be mixed in a ratio of 1:2 and poured into a spray bottle. After shaking the mixture well, spray it on grouts and mold-infested areas.

Let the mixture sit for 10-15 minutes on the molds. Scrub the surface with a sturdy bristle brush. 

It should start coming out of the molds soon.

Wear gloves and a mask while you do it as a precaution. Bleach can harm your skin. You might not like the smell while doing it.

Mold can also be removed with a bleach disinfectant sprayer if you don’t want to handle bleach. It’s safer and you won’t have to handle bleach directly.

Step#5 – Reduce Humidity In Your Home

When you live in places like Florida, you’re likely to experience hot and humid weather. 

You can also keep bugs away by controlling the humidity inside your home. You can do this by using a dehumidifier.

It is important to remember that high humidity and dampness in the home attract bugs. 

Rain and high humidity can dampen your home enough to attract insects even if there are no leaks in your home.

Make your home naturally repellent to these tiny insects by installing a dehumidifier.

You can also repel bugs from your home and bathroom by using natural sprays, such as peppermint spray.

The smell of peppermint repels bugs. It is known to be an effective insect repellent. 


The five baby bugs in shower grout are –

  1. Psocids mites
  2. Mold mites
  3. Silverfish
  4. Drain flies or Sewer flies
  5. Worms

These bugs are attracted to dampness and moisture in the bathroom.

Mold can also grow on the grout in the shower and on the floor and walls of the bathroom due to moisture.

These bugs consume molds and wastes as food. They rely on both for survival. In the event that you don’t address your home’s dampness problem, their numbers increase rapidly.

The presence of drain flies and their larvae in the shower grout and under the bathroom sink is another reason for clogged drains.

In this guide, we discussed the reasons for the presence of each of these bugs in more detail. We also provided five steps for getting rid of them.

It is easy to get rid of these bugs. You can easily eliminate these common bathroom bugs without professional pest control with a little bit of precaution.

To get rid of these bugs, you don’t need an insecticide spray. 

However, if they have become a nuisance in your home, then you can use pyrethrin-based sprays.
