The situation first came to light when a shipment of coffee beans from Costa Rica sent was sent to resident Susan Meyer in August.
The package had been chewed through by rodents and the beans were spilling out.
Then, more and more packages started arriving with tell-tale bite marks.
The post office issued a statement Friday in response to the questions from Eyewitness News saying:
"To resolve this issue we have contracted with a local pest control service. We intend to continue abatement until the situation is resolved."
Meantime, Susan Meyer says she'll have her coffee Fed Exed from now on.
