How big is the needle tip of the bug on the bed?

Bug fleas are very clever. They will lie on people's clothes or put sheets on the doors. That's because when people move, it's easier to escape. If you are in Guangdong, it's hard to find. There is a kind of bedbug flea here in Guangdong. Bed bugs and fleas come from the outside and don't grow on their own. The main ways are going out, staying in hotels, and others traveling overnight will spread bedbugs. Some customers buy second-hand furniture or rent original houses with bedbugs. Then a worm is very powerful, sucking blood and biting people, and the wound is the same as yours. I went to Taobao to find an insecticide called Jin Hui 1, which has the function of relieving swelling and itching. Just apply the scar.
