Police have sent out letters to households on Anglesey over alleged incidents of anti-social behaviour.
Seven properties in Menai Bridge have been told that their behaviour is "unacceptable" in the letters from police and Anglesey Council.
Officers said they will work with the tenants to "educate those involved on the affect the reported behaviour has on the local community".
The situation will be monitored moving forward and police say if problems continue further action could be taken.
North Wales Police Anglesey posted on Facebook: "Following monitoring and if issues continue, we can progress with enforcement and using powers available under the the Anti-Social Behaviour, Crime and Policing Act 2014.
"Clearly this is the last resort, however anti social behaviour, especially during the current COVID-19 restrictions will not be tolerated."
