Verspex is a bit of a non-starter for 'home' or smaller type jobs, $58 plus farting around to get registered and then you have to actually get the stuff on top of that which requires freezer transport etc etc. OK if you have the work for it. For the average home or lifestyle block it's just a non-starter. I looked seriously at getting the approval to purchase and complete Monsanto's product husbandry requirements but it was just too much as you can't get a small enough pack to use it all before the expiries.
Some of the over-the-counter products we tried just didn't work, literally we were feeding the bloody things and they were coming back for more! Tied a tracking cotton to a couple of wasps and counted them back at least three times. That's when I got told about the spot on, and how to not kill bees with it - that's what was pissing me off the most with the wasps the bastards were ripping the heads off the bees and taking the bodies laden with pollen back to the nest and feeding the young up on bee protein with pollen for desert. The spot on treated tuna definitely dealt to them, over two days no more wasps. Much more bees in evidence, and since then only a few small paper wasp nests of 4-5 adults (easy to sort by knocking to the ground) and very few German or Common wasps in evidence and probably at the extreme limits of their foraging range.
