Thrips, pesticide and veggie contamination

Thrips, pesticide and veggie contamination

I posted a while back on organic thrips management and it's not working. close up of the damage Photobucket they are killing my hedge Photobucket I hate this hedge and it will come out eventually. In the mean time it is the only means of sight block from my neighbors 2 story house. I have decided to call in pest control to spray something nasty. My main veggie area is aprox 100' from the end of the hedge. Is that far enough away to prevent contamination? Or do I allow their party to continue and possibly move to my citrus? I harvest tomatoes through December. I am finding lots of conflicting info. veggie garden Photobucket Zone 9a sunset zone 15 CA Thank you for any input =0)
