Use to go past the pit at manea and then over the Bedford into the Delph. It's a long walk now as the punt has gone. Where abouts are you Green lurchers
The Delph is far better for zander than the old Bedford. Seen many double figures come out of there. I had a few small ones when piking. 16ft can be hit or miss with them
I have watched many times after treatment and I reckon all the wasps attempt to go in the nest and get a dose of powder on them, either on the legs or arse . That's enough to kill them.
