insects thriving in the hot conditions, the pest control industry has
Pest Wellington had been answering up to 50 enquiries and handling 20
jobs a day, and manager Tony Behrent said things were busy
in contact with other guys in the industry, and we know everyone's
pretty busy. Quite often we can't get to jobs and we're advising
people to ring other companies and see if they can help because quite
simply people need to get things done quickly and if we can't provide
it, try to get it sorted."

Hutt Valley, Kapiti Coast, Palmerston, Manawatu, we've definitely had
an increase in the number of Gisborne cockroaches enquiries. Flies
haven't been particularly bad and I think a lot of that is due to the
dry conditions, flies tend to like a bit of humidity."

do like the temperature, they like the heat, but they also really
like relative humidity. If you dry out as an insect and you lose
water through your exoskeleton, you're in deep trouble. So the odd
shower and relative humidity - bingo. Increase in numbers, increase
in life cycles and the way they go through it, and fabulous
opportunities to breed."

Trewin, a senior climatologist at the bureau, said sea-surface
temperatures off south-eastern Australia were relatively warm,
limiting their cooling influence.
ongoing dry and warm outlook means that the fire season for many

Australia and Victoria had record hot starts to summer but
temperatures eased back to more normal conditions for the second half
