That's the question. It seems in my case I've had several whitefly infestations during spring. I've lost several ornamental plants due to them every spring. I have the perception they don't bother during summer-winter. Is this true or only my perception? I mean are they seasonal?
Are whiteflies a problem mostly in Spring?

All season until mid 40's here. I modify flystrips by cutting into 4-6" pieces. I handle and secure it spring type paper clips. Which i then use twist ties to secure between 2 sturdy branches close to my stems without touching anything. Or in reach of anything. Makes a dent for cheap. Safe and clean.

Beats the powdered white cyanide my best friends dad used from the 70's to the late 80's. A moment to him. Orny bastard helped me more than I am only beginning to understand.

There are few very effective chemical compounds that control white fly's.
These suckers are a real pain if you get them.
Oberon and Forbid are doing pretty good on these exceptional pain's in the ass.
Take a board or something long and paint it yellow. Coat that with a sticky substance. This works pretty good.....
This is from a college extension paper on White fly control as of late. BE SURE you note the parts on bug chemical resistance!
Chemical Control
Insecticides are the primary method used to control whiteflies. Many compounds have been used, but the systemic Marathon (imadacloprid) has been used most frequently over the past few years. The newer chemically related compounds Celero (clothianidin), Flagship (thiamethoxam), Safari (dinotefuran), and TriStar (acetamiprid) are also effective.
Endeavor (pymetrozine), Aria (flonicamid), and the insect growth regulator (IGR) Distance (pyriproxyfen) are new chemical classes that have activity as well. Several other effective IGRs are Azatin/Ornazin/AzaDirect (azadirachtin), Enstar II (kinoprene), Pedestal (novaluron), and Talus (buprofezin).
The newest material to be registered for whitefly control is Judo (spiromesifen). Tank mixes of a pyrethroid and orthene (acephate) are synergistic, providing better control than either orthese or pyrethroid used alone, but many populations are now resistant to such combinations. A few other general insecticides, aerosols, and soaps or oils can also be used.
The newly hatched crawlers and the adults are most susceptible to chemicals, but the waxy covering on the larger immatures makes them more difficult to cover thoroughly with spray material. Resistance is a major problem, and every effort should be made to rotate chemicals with each application. Do not rely on any one product or chemical class for whitefly control.
