The order comes as the Sinaloa Cartel has expressed concerns about the US law enforcement pressures and future arrests of its top leaders.
A faction of the cartel known as Los Chapitos, the group led by the four sons of the notorious drug lord Joaquín 'El Chapo' Guzmán recently issued the order, according to the Wall Street Journal.
The decision to lay low comes as the Biden administration has pushed the Mexican government to be stricter with the cartel that has been feeding the illegal drug into the country and causing countless deaths.
The newest message from Los Chapitos comes after El Chapo's sons ordered the murders and kidnappings of street dealers who have failed to comply with a ban on the production and sale of fentanyl.
Since the January arrest of El Chapo's one son, Ovidio Guzmán, in Culiacán, cartel members have allegedly been killed for disregarding the ordered ban.
