Whether cockroach pills have any effect on pregnant women depends on the type of cockroach pills and whether the pregnant woman is in direct contact with the pills. Roach medicine can be used in rooms with cockroaches to eliminate them, and there are two types of cockroach medicine: liquid and solid. Generally speaking the solid type of cockroach poison is odorless and has little effect on pregnant women. Liquid cockroach poison is sprayed in the air and inhaled by pregnant women, and a large amount of prolonged inhalation through the mucous membrane of the respiratory tract and infiltration into the blood circulation may have a certain effect on the fetus. If a pregnant woman is in direct contact with cockroach medicine, it may affect the development of the fetus, and in serious cases, it may cause miscarriage or cause malformation of the fetus in the abdomen, so it is recommended that during pregnancy, the room should not use cockroach medicine, usually pay attention to clean the room, and cockroaches can be killed with a beat.
