Keen gardeners Gwen and Lindsay Wilson have unwanted
venomous visitors: wasps have made themselves at home in the
bottom of an old clothes dryer the retired Invercargill couple
have been using as a planter box for potatoes.
They first noticed the wasps on the weekend of the 12th and
13th and reported them to Environment Southland early last
The council does not usually inspect properties affected by
wasps or eradicate the pests, but as the Wilsons live just a
block from the council offices, council biosecurity officer
Chris Morison visited them last Monday and squirted a toxic
powder into the nest entrance.
Unfortunately, that was ineffective, Mrs Wilson said on
Mr Morison returned to give them another dose on Friday. If
that did not do the trick, Mrs Wilson said, she would resort
to more drastic measures.
''We've been talking to our friends and someone said wasps
don't like petrol fumes because they breathe through their
entire bodies. So we might try that.''
Mr Morison said he had calls daily from people all over
Invercargill and parts of rural Southland bothered by wasps.
It was an annual problem which began in January, peaked in
late February or early March and continued until about May.
Queen wasps began to breed in the spring and continued
through the summer, he said. People began to notice wasps as
hive populations grew and more wasps flew about looking for
Wasps were a major pest and home owners were encouraged to
eradicate them, he said.
