On one hand, a commercial pesticide is sometimes an effective way to quickly kill off the pests. The whitefly, however, is notoriously resistant to chemical products. Furthermore, these chemicals are often toxic to other organisms in the immediate ecosystem – including the plants and benign insects in your garden, pets and local wildlife, and even your family. Try to keep pesticides as a last resort. Indeed, the eggs and pupae are able to resist most common insecticides. If you do use chemicals, be sure to switch them out in several-day rotations to keep your fly population from adapting. Even so, there is a strong chance that the whiteflies will adapt. You may unwittingly create a strain of pesky super-flies!
