Whiteflies on Hibiscus: Nighttime Soap Spray Treatment

Why Night?

Whiteflies are less active at night, reducing fly-away during treatment.

Step-by-Step

1. Vacuum winged adults off leaves with hand vac.
2. Spray all leaf/stem surfaces until dripping with liquid dish soap solution.
3. Do outdoors if above freezing—contains mess and escapes.
4. Cold kills escapees; soap kills on contact.
5. Thorough coverage usually eliminates need for re-treatment.

Monitor

Watch for live flies. Dead bodies falling is fine. Vigilance prevents reinfestation.
