I have suddenly been overrun with them, if I touch a leaf outside they fly everywhere, I did spray yesterday with a mixture on the hose but does not look like it has touched them , any suggestions.
They totally stripped my brug of all its leaves, guess I better dig it up and put in pot to try to save it.

I had a similar problem. I've planted marigolds near my brugs and the problem is solved. I tried every chemical available in the big box stores with limited success.

I've read that white flies become immune to chemicals that are used repeatedly so you need to rotate what you use. I had the best success with Bayer Advanced liquid however my success was limited.

Plain old blue dawn dish soap and water works wonders for me Just be careful because Dawn can be strong for some plants. I have been using
Dollar General cheapo dish soap since it is milder and it still does the trick.

I agree, soapy water is the trick. They never get immune to it, because it kills them mechanically, not by poisoning.

You need to spray with a fine pump sprayer, not the hose. Cover all the leaf surfaces, undersides as well as upper, and all the stems. A mild solution is best, about 2tsp. of any dish soap per gallon. Stronger is NOT better, and can hurt the plant. You probably need to do it a couple of times a week for a couple of weeks to get all the adults, then all the new ones hatching out. Then keep a close eye out in the next week or two for any more showing up.

Very important! Don't spray the soapy water onto the leaves when the sun will be on them (evening is best). Even a mild soap will burn the leaves if the sun hits them while the soap is on there.

I don't know if digging it up right now will help anything, Doris. Use the soap solution, let the plant recover before you traumatize it by transplanting.

Regular fly spray also does the trick.

The problem with the Bayer type sprays, or systemics is that bees and butterflies will die if they go to any of the plants' flowers. The systemics will last in the plants' system for a year. We need to do what we can to keep their populations healthy.

We had a massive problem with white fly last year in Florida. I used the soapy water solution also. Here's the recipe, recommended by our county Ag agent.

2-1/2 tbsp of cooking oil, plus 2-1/2 tbsp of baby shampoo. Mix in one gallon of water.

You do need to wash it off within a few hours. Spray ever 5-7 days as needed. This also good for mealy bugs. When I saw the eggs on the undersides of the leaves, I also just hosed them off, as the eggs wouldn't be viable on the ground.

Something else that does work, is using yellow plastic plates smeared in Vaseline. The flies are attracted to yellow. I hang them near my tomato plants. just make a hole in the plate's rim and thread string through and find something to hang it from. When the plate gets yucky with the bad bugs, and it will, just make up a new one.

I tried the soap a water thing first. It did nothing. I finally used Abamectin 0.15 EC. Very happy with the results.
