Does anyone have any experience with ‘Safer's Insecticidal Soap’ and whiteflies? I’d like to know if it can kill them quickly and effectively. Thanks!

Sharon, Bayer Advanced Rose and Flower Care is a systemic, the only thing I can think of besides a systemic and malathion or neem oil is liquid Sevin. That does kill caterpillars and anything on contact but won't affect any of the insects looking for nectar. Flying insects are very hard to control. I had a very bad white-fly infestation once in Tampa on all my Golden Dewdrops, I thought I would never get rid of them. And I think there is a newer variety that has come in the last few years that are even worse than the normal ones, I hope you don't have those.

Bob Tanem in Northern CA (Sunday morning KSFO radio show) has for years said that he uses old coffee grounds after you make your morning coffee. -Babka https://www.bobtanem.com/recipes-for-pests-and-diseases Solution #2: This is my favorite organic solution: Place 2 lbs of old coffee grounds in one gallon of water. Bring to a boil, cool and run through a coffee filter. Spray on infested plants.

Also my concern which is why I posted... this year white flies are in mass in my fall garden. I used a spinosad week or so ago to no affect, in fact whiteflies are worse. An arborist recommended Dominion to me for all my garden pest he said they have found it to be least damaging overall. I love all my bees and ladybugs they are my friends. This supposedly does not harm them or the earthworms if used as a drench. Whiteflies are tough. I have been using yaed guard when outside with guest for the mosquitos which have been terrible. I fear I killed my good guy in the process. Everyone walks my garden and I was trying to prevent bites also west nile on the dogs.
