Refuse

What I would like to know is why I should contain mt house refuse in plastic bags before putting it into the refuse bin. Also, I am spending money monthly to sanitize and keep my bin clean. The Municipality is allowing vagrants to indiscriminately tear open the refuse bags and litter. The refuse trucks are mainly late by sometimes a day or two leaving the residents to daily pick up refuse. As the refuse trucks officials do not pick up what has been emptied on the ground we paying residents are left with this mess. This during the pandemic is becoming a health issue as the vagrants rarely wear masks and maggots, brommers and worms are breeding.
