Apple Maggot Quarantine
Counties may be quarantined in whole or in part based on trap catches and other evidence of apple maggot activity. The quarantine aims to slow the spread of apple maggot in Washington.
The purpose of the quarantine is to facilitate the movement of commercial fruit to domestic and international markets by providing shippers with one of two types of WSDA documents certifying their fruit is apple maggot free:
- A certificate stating no apple maggot flies were caught within half a mile of the orchard shipping the fruit.
- A certificate stating flies were caught within half a mile of the orchard but that WSDA inspection revealed no apple maggot larvae in the fruit.
