Greetings:
I can't be bothered with concoctions -got other things to do with my  time
Tangle-Trap  ----- Insect Trap Coating is the stuff to use
Look up  The Tanglefoot Company -Grand Rapids Michigan
In Canada Ontario Seed Co carries it.
A 5 1/2 oz tube goes along ways and it's cheap.
For a  really good sticky board use a wide scraper and apply this  stuff 
really thin, just so that the surface shines. (use a piece of 1/8th inch  acrylic 
or uhmw plastic tacked onto masonite etc ) Cover with 8x8 mesh  and slide them 
in.
