I don't realy get your question.. I think you meant to ask:
   Can my USB flash stick used to capture Wifi packets.?

Well Yes and No.
Yes you can store the PCAP files you got though some wifi interface on a flash stick.
No there is no Wifi tuner, controller & antenna in a usb flash stick.

A flash stick is nothing more then a large capacity EEPROM, so it can only store data  & reproduce the stored data.

No it cannot. It lacks a tuner, antenna, microprocessor,.. needed to handle wifi traffic.
You can just use it as a storage device like a floppy disk, portable harddisk...

I don't known where you got that idea ...

there are USB sticks, (NOT flash) that can handle WIFI, they are sold as such.

Here is an up to date list of tools:

To capture frames the network adapters need to be capable of either RAW mode receive or promiscuous mode.
(Kismet should have a lot to tell about this as it has some history on this subject).
