Wine growers are installing bat roosts around vineyards to get bats to feed on grapevine moths. The moths and their larvae have insatiable craving which can clear out half of the grapes in some vineyards. Vineyards have been forced to use pesticides to reduce grapevine moth infestations, as their larvae feed on the inside of the grapes and leave hollowed out grapes and feces everywhere. Multiple species of bats like to feed on grapevine moths and cochylis moths more than any other insects. Wine growers are installing bat roosts around their vineyards to rid themselves of the moths with the goal to radically reduce the volume of phytosanitary grape pesticides.
