My garden has been relatively free of whiteflies in recent years. A decline in the neighborhood infestation occurred when two large hibiscus bushes, dripping with whiteflies, in nearby yards were finally removed by the owners.
Recently. after running my hands through my ‘Tuscan Baby Leaf Kale’ a cloud of whiteflies emerged.
I recalled making whitefly traps in my earliest gardening days after reading the research about the insect’s attraction to a certain bright yellow Rustoleum spray paint. We made little masonite squares which we spray-painted, coated with Tanglefoot and mounted on stakes in the garden.
Rummaging around my garden shelves, I found this trap. I think it came from my Dad’s garden leftovers. So I deployed it.
Before long, the whiteflies found it “attractive.” A Google search showed a newer version is still available.
The University of California IPM website recommends “ Protect natural enemies such as lacewings, lady beetles, and mini-wasps.” I’ll leave most of the control to the natural predators.
I read Quick Tips: Whiteflies on the site and found useful suggestions for control. Check it out if your garden is frequented by whiteflies.
