Spraying plans to combat the Mountain Pine Beetle in some Bitterroot National Forest recreation sites have been delayed, due to rainy conditions.

A slow moving cold front has spread rain throughout the Bitterroot Valley Wednesday and weather is expected to be "unsettled" through the weekend.

The forest crews were going to spray carbaryl at Lake Como and at campgrounds in the Sula and West Fork Ranger Districts.

Joni Lubke of the Bitterroot National Forest wrote in a news release that work will resume next week (June 24) - weather permitting. Sites that may be closed next week include the Lake Como area on the Darby Ranger District and Indian Trees and Spring Gulch Campgrounds on the Sula Ranger District.

The spraying needs to be completed before the annual "flight" time of the beetle later this summer.
