Cockroaches Move Indoors

Bush Cockroach
New Zealand native Bush Cockroaches are invading homes where warm moist weather in parts of the country is encouraging them.

There are about 15 species of Native Bush Cockroach. They are small wingless cockroaches, up to 15mm body length. They can often be mistaken for the Gisborne cockroach which is also a 'Wood Cockroach' like the Bush but is more likely to be a nuisance pest. The Gisborne will grow much larger; growing to over 30mm.

The Bush Cockroach normally lives in logs and leaf litter or under loose bark. They prefer damp, dark habitats and are not usually a household pest. However, when they do invade a home,wandering in from the garden or brought in on wood for the fire, they can cause a certain amount of revulsion and consternation.

They will not survive long in most homes as it is too dry where there is heating and there will be a lack of their normal food of rotting vegetation. But 'not long' can be several weeks and it maybe that home owners want to get rid of them sooner.

Preventing the entry of Bush or Gisborne cockroaches to the house or other buildings is the first thing to do. Make sure doors and windows are tightly fitting and keep vegetation and bark chips away from the house. Don't store firewood close tot he house and take care when bringing the wood indoors not to carry cockroaches with it.

The use of residual insecticide such as NO Bugs Super inside and around the walls and possible entry points can deter the roaches and shorten their life in the home. But it is not necessary to use insecticides in the garden where they cockroaches are not a threat and pose no risk of harm. It is only when they move inside that that can be a nuisance.

"I was in that new restaurant across the street," said one roach to his mate. "It's so clean! The kitchen is spotless, and the floors are gleaming. There is no dirt anywhere--it's so hygienic that the whole place shines."

"Please," said the other roach. "Not while I'm eating!"
