We have had reports of whitefly problems various areas of the state. Whiteflies do not overwinter well in Kansas but can build up later in the season due to migration from more southern climes, buildup of local populations and introductions from transplants.
Whiteflies do not tolerate cold temperatures and will likely disappear toward the end of next week. Therefore, control measures are not needed unless you have houseplants that have been growing outside. Check carefully for whiteflies before bringing them inside for the winter. In such cases, try insecticidal soap, neem based products, pyrethrin, or Ortho Rose and Flower Insect Killer. (Ward Upham)
