| Hi, I have a bad infestation of white flies in the back yard. The ortho big book said to spray every ? 4-6 days as they drop eggs frequently. After about 7 different spray applications, we still have!! Help! What do I do? Thanks. |
| I'm sorry to say - you're doing everything right! Whiteflies are really difficult to control. Insecticidal soaps work well against white flies. Just be sure to spray both top and undersides of leaves. Insecticidal soaps can cause burning of leaves if applied during hot weather, so use caution. Whiteflies are generally settled on plants in the early morning and late evening hours so that's the best time to spray them. Good luck in getting rid of those pesky pests! |
