What Are These Tiny Grey Bugs in Your Bathroom?

There are four main types of grey bugs that tend to intrude on bathrooms in the home. These are silverfish, stinkbugs, drain flies, and fruit flies.

Most of these bugs have the same reasons for wanting to live in your home, but none of them are something to worry about.

Silverfish

Silverfish are small insects with six legs and a fishlike appearance that cannot fly. These bugs are a light grey color with a silvery shine to them. Their diet of choice is carbohydrates and starchy materials.

Silverfish are not harmful to humans and will not bite. They can, however, destroy fabrics such as towels and clothing by gnawing at the material. 

Stink Bugs

Stink bugs have a light brown or dull grey softshell that has a teardrop shape. As a defense mechanism, these bugs will emit a foul smell when they feel threatened as a defense mechanism. 

These bugs have six legs and can fly. Stink bugs do not bite; however, many people can be allergic to the compounds they release.

Drain Flies

Drain Flies are extremely small and come in various colors, with many of them light or dark grey. You can tell these flies are apart from other bugs because of the vein-like pattern on their bodies.

These bugs also have six legs and tiny wings. 

Drain flies do not cause any threat to humans or pets but can cluster together in large groups, becoming extremely intrusive.

Fruit Flies

Fruit flies are another example of teeny tiny bugs that fly around, causing a disruption in many homeowners’ bathrooms. These bugs can be grey and recognizable red eyes.

While this bug is known for infiltrating many kitchens, they also enjoy making bathrooms their homes.

Again, these bugs are harmless and do not bite. 

Mosquito

Unfortunately, Mosquitos are not only a huge problem in the outdoors. If these bugs can find a way inside the home, they can and will find a water source to lay eggs and live. 

Mosquitoes are most often grey in color with skinny oval-shaped bodies with noticeably long legs and a long “nose” used to feed on the blood of you and your pets.

Why Are There Grey Bugs in Your Bathroom?

The answer to this question is simple; you have bugs in your bathroom because bugs thrive on moisture.

All of the insects listed above are drawn to water, and many of them are dark, quiet, and secluded places as well.

The love of moisture is the reason you often see these little guys in your sinks or around your shower.

If you have any types of leaks in your bathroom or your home has humidity problems, you will likely find an infestation of one kind or another.

Where do These Tiny Grey Bugs Hide When I Can’t See Them?

Unless you catch these bugs during their active hours, they tend to make themselves scarce in order to stay out of harm’s way.

This means hiding where you don’t tend to check often and can confine them from the outside world.

Silverfish

Silverfish like dark, moist spaces such as underneath the bathroom sink or in the closet.

These bugs can’t fly and are not the best at climbing, so you will often see them out crawling across the bathroom floor, especially on hot, humid days.

Stink Bugs

Stink bugs are also attracted to areas that have plenty of moisture and can be found all over your home, not just the bathroom.

However, the bathroom is one of their favorite places to hide, mostly when the sun is up and it is bright and warm outside.

During the day, you will more likely than not find these guys sitting on your window sill or right near the light fixtures as they are attracted to light.

Drain Flies

If the grey bug you have concerns about are coming out of your sink or shower durian, your problem is most likely drain flies.

These little guys enjoy munching on sewage and waste and hanging out in your bathroom between meals.

These flies are often attracted to groundwater and will make sewage systems outside of your house their home. 

Fruit Flies

Fruit flies are attracted to rotting items and moisture, which makes your bathroom garbage one of the biggest hideouts for these insects.

You can also find them hiding in the floorboards or inside cracked or broken tiles.

Fruit flies are not afraid to hang out during the day and often come in swarms, making them easy to find and identify.

Mosquitos

Mosquitos are highly attracted to standing water sources. These sneaky little bugs can thrive inside gutters and can easily enter your home through drainage pipes.

Mosquitos are not only attracted to water but also humidity and will often be seen close to the window.

How Do I Get Rid of These Tiny Grey Bugs?

The solution will be pretty similar for all of the bugs listed in this article.

These little pests are mainly after the wet, damp, humid, and dark places around your home that will provide the essential living conditions for them to thrive.

If you have an infestation, you can do a few different things to kick them out and keep them out for good.

Clean The Bathroom Thoughrouhly

Always keep your bathroom in tip-top shape. This means washing and drying the floors, sinks, and bathtubs regularly.

Use bleach while cleaning these areas to sanitize the space and repel the problem.

Make sure everyone in the home is drying the floors after every shower and the bathroom rugs are being washed at least once a week.

Another important factor to keeping your bathroom bug-free that many people may not even think of is cleaning out your shower and sink drains.

Over time these areas collect grim and debris that might make a yummy meal for many insects.

Repair Your Bathroom

Because these little grey bugs can fit into some of the smallest spaces, it is essential that you keep cracks filled and broken floor or wallboards repaired.

You also need to repair any leaky faucets in the room or dripping pipes from underneath the sink.

Under the sink is one of the most common areas of concern when it comes to insect infestations because it is dark, wet, and unoccupied, making it a safe place to lay eggs and hide.

Purchase Over the Counter Bug Repellent

If you have tried to clean and repair your bathroom, but these bugs are still present, it is probably time to go out and grab some over-the-counter bug repellent or bug killer.

There are natural products out there if you want to keep a chemical-free home, or you can purchase house bombs and other sprays that require a lot of care when using.

Please read the label of every product you plan to purchase to ensure it is suitable for the bug you are dealing with.

You also want to take all necessary preparations to ensure none of your belongings get damaged during the process.

If you have children or pets, be especially careful when going for the chemical killers, and make sure the area is safe before letting either back in the room.

Call an Exterminator

If the infestation gets really bad or you can’t seem to get rid of the issue on your own, it might be time to give the professionals a call.

Exterminators are very knowledgeable on all types of bugs and the best ways to get rid of them and their eggs at one time, riding your bathroom with these unwelcomed guests for good.

An exterminator can also get the job done with professional equipment and gear, keeping you and your family safe.

Summing Things Up

If you have tiny grey bugs crawling around your bathroom, you are not alone. It can be hard to keep insects out of the house and scary if you don’t know what they are.

Hopefully, this article will help you identify which grey bug you are dealing with and guide you in the right direction to get rid of them for good.
