Note:  Once established... Whiteflies are Very hard to control.

1.  Keep the growing area clean and free of fallen leaves.
(Keep the Greenhouse area as clean as possible)

2.  Carefully remove and place badly infected leaves into trash bags.

3.  Blast all existing leaves clean with a water hose.

4.  Keep pots and all growing areas free of weeds.

5.  Improve the air circulation in greenhouse area, and as weather permits remove plants, and blast them clean and free of all adult whiteflies.

6.  Use "yellow sticky traps"... place them all around the greenhouse.
***shake plants to force them to move to the traps ***
(every adult female killed will help in whitefly control.)

7.  Insecticides :  Bug-B-Gon insect killer or comparable spray product.
Bug-B-Gon Multi-Purpose Garden Dust or comparable dusting product.
***repeated treatments are needed to gain control ***
