Whitefly eating insects

[CrazyConure]

I bought ladybugs to eat whiteflies, but they only ate the aphids and left. We have a pretty big whitefly problem in Miami because there are no whitefly predators. What is the whitefly's biggest predator? What plants attract it?

I have a friend who has a very large greenhouse and every so often he sends off for a type of beetle about the shape and size of a ladybug but it is solid black. He waits to order them until there are a lot of whitefly present then he closes up the green house so they can't fly off. Only thing wrong is that these black ladybug insects are EXPENSIVE. He says that they are the best thing for whitefly control because they eat the eggs, nymphs and grown whitefly and they do it rapidly. To him money is no object though. Other than these insects the only good method of ridding yourself of them is to regularly spray with spinosad and neem. Mix the neem with a dose of Safers. It will take more than one application.

some people use soapy water plus boiled crushed garlic, you could also use a cellotape to go round the plants and these critters will be removed by the tape. Very therapeutic, or use a provado spray..

Lacewing larvae is also a natural predator of whitefly.
