White Flies

Cuthbert 9/7/2015, 2:38 pm

Beside my SFG, my wife has a lot of ornamental plants. Yesterday, as we were sitting under the fans on the patio, we observed a swarm of white flies descending like a swarm of locusts on pharaoh in Egypt. I've never seen them like this. Any suggestions? Plants are already covered in sticky sap.

Since they are ornamentals, Dr. Bronner's liquid soap solution or neem oil solution?

For the first time ever White Flies have showed up in my cold frame. I mixed up a batch of homemade insecticidal soap and sprayed all of the plants. Since it is a closed environment, I didn't have to worry about beneficial insects being affected by the soap so I could spray heavily. Will check tomorrow to see if re-application is going to be necessary.

This year was my worst for white flies and aphids, but especially the white flies. I used spinosad, insecticidal soap and Dr. Bronner's Liquid Peppermint Soap alternately. I think the Dr. Bronner's actually did a very good job considering how inexpensive it is.

I make my own insecticidal soap instead of buying a ready to use one. It is very simple to make, very economical, and very, very effective.

1 qt warm water
2 tsp Dr. Bronner's Peppermint Pure-Castile Liquid Soap
2 tsp Vegetable Oil (I use either Olive or Coconut)

Cap tightly and shake sufficiently to emulsify the oil & soap. Pour into spray bottle to apply - shake regularly while spraying.
