If plants are infested, consider discarding them. Feeding on flowers can cause them to wither and die. Cyclamen make lovely houseplants during their bloom season. Some mites appear as barely visible red and gray, slow-moving specks, while others are microscopic, requiring optical equipment for identification. They are not visible to the naked eye, and when mature, they only measure about 0.01 inch (0.25 mm) long. Leaves heavily infested with cyclamen mites become severely stunted and crinkled, resulting in a compact leaf mass in the center of the plant. Make two applications 7 to 10 days apart when mites reach detectable levels under warmer temperatures in late winter or spring. New plants that might harbor cyclamen or broad mites should be isolated from other susceptible plants for several weeks so that they can be monitored for symptoms typical of a cyclamen or broad mite infestation.

Once the blossoms fade, the plant enters a period of dormancy, and they can look as though they are dead. Some plants become infested with cyclamen mites, pests that are very difficult to control. Preharvest interval (PHI) is the number of days from treatment to harvest. The follicle mite is more worm-like. They like to hide in buds or tips of new growth. Today, it is generally distributed throughout the country. To prepare plants for this treatment: (This treatment is not recommended for fresh-dug transplants that have only been stored at 33°F.).

Cyclamen mite numbers increase rapidly soon after a field becomes infested. Cyclamen look wonderful planted in containers. Rotate insecticides with a different mode-of-action group number, and do not use products with the same mode-of-action group number more than twice per season to help prevent the development of resistance. When cyclamen get too much fertilizer, it can affect their ability to rebloom. However, cyclamen and broad mites are sensitive to heat and can be killed by dipping plants in a 111oF water bath for 15 minutes. The large butterfly-like flowers hang from 2- to 4-inch-tall stalks.
