Any untaught ways to hang on to the white fly sour vegetable plants and the fruits? I live in Florida, and the tiny white insect/fly will not stay...

I live in Florida, and the tiny white insect/fly will not stay of my tomatoes and other veggies. I be wondering if there be any 'natural', safe ways to find them off and 'keep' them past its sell-by date of the vegetables.
Answers:    Most natural would be female beetles which you can purchase if you don't go and get them naturally contained by your garden. Then, there is other 1 tbs of dish soap (any will work), 1tbs of lite cooking oil (canola), within a 32 oz spray bottle of water. Spray this solution on the plants making sure to return with the tops and bottoms of the leaves as well as the stems and trunks. Aphids or white fly are soft bodied insects and the soapy solution will destroy them on contact as it will most garden insects.

Good Luck
Sweetbay/Hannaford brand dishwashing liguid. I would say roughly a tablespoon to a quart of water contained by a spray bottle.

I like the Hannaford brand because it have an aroma that is slightly chemically but within a reassuring instrument. I use it indoors and out.
