Aspen, Colo. (AP) - Aspen is battling a bumper crop of aphid bugs on trees this year.
City officials say the cool, rainy spring has led to a bumper crop of aphids, also known as plant lice.
The small bugs nibble leaves and leave waste that covers cars and sidewalks a sticky mess.
City of Aspen Forester Chris Forman says this year's cool spring led to the rise in aphids. That's because predators of the aphid, including ladybugs and lacewings, have slowed their activity in the cool weather.
The City of Aspen has been using insecticides against the aphids for the past week. The city is also encouraging homeowners to check their trees and apply insecticide if they see the small green pests on the undersides of leaves.
