If the cockroach has not bitten the scalp area after crawling on the hair, it will not be infected with the germs carried by the cockroach’s body. However, if the hair has been crawled by the cockroach, there is a possibility that the eggs may be left behind, causing atopic dermatitis.
The eggs left behind may cause allergic dermatitis, which may result in erythematous pimples and itching on the scalp, and may even cause abdominal pain and diarrhea when accidentally ingested into the gastrointestinal tract, which is not conducive to the patient’s health. So usually pay more attention to indoor dryness and cleanliness, good protection.
Usually you can use insecticides to eliminate cockroaches, and the dark and damp indoor places should be cleaned regularly to prevent cockroaches from gathering.
