Why are there black bugs on the bed?

There are many reasons why there are bugs in the bed:

The main reason is that daily cleaning is not in place. In our real life, many people like to eat in bed, which is the easiest way to attract bugs to bed. The most common bugs are ants and cockroaches. Secondly, sheets are different from our daily clothes. We wash sheets at most once a week, which will also lead to the breeding of mites. In addition, many communities are located near rivers or ponds, which will cause all kinds of bugs to fly into the bedroom. If these insects lay eggs on the bed, they will produce all kinds of insects.
