Do white flies survive the winter outside?

-I bought some plants at WalMart this spring and potted them up in new potting soil and new containers, but later some of them got attacked by white flies, those tiny little critters that lay eggs on the underside of leaves.

The adults will fly up in alarm if you brush the leaves with your hands.

The ones that had it I moved to the porch and sprayed with insecticidal soap, actually several times.



Now I not only still have plenty of them, they've attacked other plants on the other side of the porch.



If I dump the soil out this winter into the garden, will the white flies survive the winter and come back to haunt me again in the spring? It gets down to the teens here even though we are in the South.

I have a lot of soil that I'd like to save, but would I do better to take it to the dump?If you have the room for one you should always have a hot compost pile in which to renew and rejuvinate soils in. A hot pile can get to a hundred and fifty or sixty degrees and kill any pathogens or weed seeds that may accumulate in your soils. That is better than throwing the soil away. It only takes about four feet by four feet to accumulate enough mass to heat to those temperatures but the piles must be kept barely moist and turned twice a week to keep the oxigen level high. It is good exercise and cheaper than a gym membership. I credit my good health to aerobic compost turning over the years. By the way, I kept three bins five feet square each and four feet high. That's a lot of tons turned each week. Kids have called me Popey. Ha.



Namaste'I am not positive, but wouldn't the eggs survive? After all, warmer human buildings are recent in their species life. So if you want to be sure, take the remaining soil to some more distant place than your own garden.



(((Sara's plants))) I'd avoid stuff from WalMart.

That's all from China.
White flies will find shelter and go dormant for the winter, but if you can spread the soil out so it will thoroughly freeze they, their eggs, or larva, are not likely to survive.
I would not worry too much about that. The natural predators that are outside willll take care of a lot of them. The thing about those flies is that a green house is a really good shelter for them.
PLEASE HELP ,
