Wasp Grubs & Wasp cake (the nest cells) was a killing bait mainly for Chub on the Yorkshire rivers in the 60's to 90's.
Anyone still using it??
My Uncle used to dig up wasps nests after treating with cyamag (Magnesium cyanide).
Could also buy from tackle shops - frozen & wrapped in newspaper, but the grubs would hatch out as wasps when thawing as you were fishing!!
A needle or tweezers to kill them as they hatched sufficed!!
