The drain flies indicate filthy drains, and booklice suggest mold, which you should take care of.

How do they enter?

Although they might seem to be coming from your drain, this is usually not the case. Most likely, the infestation began on the outside through a window or door, but drain flies do breed in drains, and we usually only notice them after they have become a significant problem. There’s a very high probability that earwigs are external. Especially if you have a window in your bathroom on the ground floor, they could be coming through there.

Earwigs tiny black bugs in bathroom prefer a warm, moist environment, so if the conditions outside become unfavorable, they might seek shelter in your bathroom.

Throughout the home, booklice feed on whatever they can find. They tend to be brought into the house with various objects (like old books) because they are so tiny.

Will the tiny black bugs go away on their own?

Your bathroom is unlikely to disappear by itself if you have tiny bugs. If you provide the bugs with favorable conditions (e.g., slimy material for laying eggs), drain flies can live in your drain for some time. Drain flies and booklice like humid and warm conditions and will stay in your bathroom as long as you provide them with those conditions. 

There are relatively few earwig infestations, often brought in from the outside. They may go away on their own, but it’s certainly safer to kick them out by yourself.

How to get rid of the tiny black bugs in bathroom?

You should choose who you allow living in your home, even if minor black bugs are not hazardous in your bathroom. There are some practical solutions you can employ to eliminate these unwanted guests.

1.    Clean your pipes and sinks.

It’s a good idea to turn off the water before you begin cleaning the sink. Make sure you clean the pipes with a brush, open the P-trap, and remove any leftover blockages. To kill eggs, larvae, and bugs stuck to the walls, pour enzymatic cleanser into the pipes.

2.    Wash the bathroom.

Make sure the entire bathroom is clean from top to bottom. Remove all surfaces that can be reached, and then thoroughly scour the drains. Make sure any remaining sludge is removed. Bacterial gels can be used for this. By pouring the bacterial gel down the drain, you will dissolve all organic wastes, as well as shampoo, soap, hair, and dead skin cells. The best part of these gels is that they won’t harm your plumbing, but they will dredge the drain so that water won’t accumulate at the bottom of the tub.

3.    Utilize a trap.

If you have black bugs in your bathroom, you can get rid of them using a trap. In a smaller bowl or jar, combine many drops of liquid soap, vinegar, and sugar. Leave it at the sink for about one week. Once the tiny insects are gone, the sink will be clean. If the insects keep returning, you may have to contact an insect control company.

4.    Make sure the garbage can is clean.

The garbage can needs to be cleaned well and disinfected. Keep it dry and empty at all times.


You don’t have to be concerned about tiny black bugs in your bathroom, even if it seems like something from a horror movie. Bathrooms are commonly infested with drain flies, mainly if the space isn’t used very often. The good news is that you can remove them yourself without too much difficulty.
