HONOLULU (AP) - Hawaii agriculture inspectors say Christmas trees are arriving in the state infested with slugs.
Sixty shipping containers were inspected over the weekend and slugs were found in six of containers.
The Honolulu Star-Advertiser reports 50 percent of containers last year were found with slugs or other invasive pests.
The Hawaii Department of Agriculture says in an announcement that Oregon Department of Agriculture inspectors are watching the Hawaii inspections.
Hawaii officials say Oregon this year increased monitoring of the harvesting and shipping of Christmas trees to Hawaii.
Two Hawaii inspectors are back from watching harvesting and packing of some of the trees that arrived over the weekend.
The department says trees with pests will be treated with hot water.
