Bedbugs are the bloodsuckers

Hallo steemian friends, good afternoon.
This afternoon I want to introduce bedbugs to my steemian friends.
Earlier I saw a bedbug standing on the leaves of sweet potato, this bedbug is a type of animal that contains bacteria and carry disease.
But I wonder, why is this stomach lice standing on the leaves of sweet potatoes?
Do these bedbugs consume cassava leaves as staple foods?

Apparently not, this bedbug just stood just above the leaves of this sweet potato, the bloody sucking bleeding on the bed when we sleep.
Be careful of friends with bedbugs.
because he is very dangerous.
