Wikipedia Is there a ulraviolet light to kill aphids?

I know of none. Most light traps just use the UV to attract & then a glueboard or grid does the dirty work. Since aphids are isolated to the plants I would just spray them for immediate results. Try ECOPCOACU or ARX-completely organic & really kills effectively. These are examples of 2 eco sprays that will even work on bedbugs which are tough buggers.
