I found today the acids (mixed Z-E isomers geranic & nerolic) in the
'95 supplement of the Aldrich price list:
item # 42,776-4 supplied as 25 ml or 100 ml (BEF 1209 and 3360)(about $34
and USD96 but this may vary a lot from a price list to another)
Thanking you, Justin, for all your great interest comments : I'll use
them all ...
*** No hexane - PE plastic - 2 smaller tubes - black paper ***
I should add that I'm also using these lures when ...
* I'm shacking bees in nucs or any hive boxes to increase the direction
wave.
* There are some lost bees after a work (in my car or each room I worked),
joined together a small piece of comb.
