Good Day,
Just read the article on wasp problems in Central Hawks Bay.  Using a digger
to expose nests is very expensive and labour intensive. There is a new
product on the market called vespex, a Kiwi invented bate for the eradication
of wasps.  Check it out, it could save a lot of money as it is set as lure
bate and killed 95% of the wasps in the Beech tree forest in South Island
during trials by MAFF and DOC. Could save the council and rate payers a lot
of money.
