There are bugs in the bathroom

I can't see it clearly, if it is a mollusc bug, it should be a slug, also called a slug, you are a relatively small kind, generally harmless, to be clear and simple, alkaline, salt, dry can be killed, it should be what long-term wet place in your bathroom, there will be these small things, the kind of bathroom disinfectant that is usually prepared at home (such as 84 disinfectant) can be solved, usually keep it dry, some sanitary dead corners, good disinfection will be fine.

You can use some insecticide first, treat it temporarily, and then find the source of the unclean bathroom to eliminate the small insects from the source.

After taking a shower, turn on the exhaust fan, open the window for ventilation, keep the bathroom space dry, put a cloth on the basin counter, wipe it off in time if there is water, and put the toiletries in a high place. The most important thing is ventilation and drying.

This insect is usually caused by a leak in the sewer pipe in the mezzanine of the wall. It is usually caused by unclean sewers, and damp and dirty environments will breed such small insects. Salt or something can only be cured temporarily.

In the long run, to stay dry, just buy some moisture-absorbing desiccant. In general, most houses that have fallen into disrepair have such problems. The new house is not very important, and the old house is difficult to get in order, so you have to smoke it.
