Why don t the toilets have millipedes, but the bedrooms?

Because the whole unit is an air duct. When the wind direction is not conducive to exhaust air from the upper part of the air duct, it will return to the smell, resulting in odor in the room.

If, as you said, the toilet is very clean, and the floor of the room is often mopped, but there are still insects, then the insects should be parasitic on the mattress or wardrobe, it is recommended that you buy an insecticide and spray the room inside and out, for a thorough pest control operation. Hope to be able to solve your problem, thanks.

There can be as long as you are willing to eat.

During the operation of the train, the urine and urine will be discharged directly to the railway station, and the toilet will be closed when the train enters the city and arrives at the station, in order to maintain the hygiene of the station area. At present, the train into Tibet adopts the collection of feces, and the feces are processed after arriving at the station, rather than being discharged directly to the railway. >>>More

Because it belongs to the corner and is the place where insects love to visit, the most important thing is to do a good job of hygiene, don't miss the corner place, rinse it with water every day, or put a box of cool oil.
