Blossom Midge

Blossom midges are little, gnat-sized flies. Due to their small, flies are difficult to spot, so keep an eye out for any harm they may cause. Inside of unopened flowers, midge larvae eat. This can cause the flower to never open, give rise to distorted blossoms, and harm the petals. Unopened flowers can fall to the ground.

Because the larvae are inside the galls or buds, where the insecticide can't reach them, gall or blossom midges are difficult to manage using insecticides. Removing the infected plant parts and picking up any buds or other plant parts that fall to the ground is the best way to control an infestation.

Never compost plant matter that has been infected. Instead, burn the trash after carefully bagging it.
