Cockroaches on your Property? Here’s how to handle them

Are Cockroaches on your Property?

Summer this year has beaten some records in heat and humidity around NZ. With rising temperatures many Kiwis without adequate insect protection have seen a rise in flies, mozzies and cockroaches in their homes and around their properties. Auckland homeowners Mr and Mrs Gravett made the national news recently when they showed the thousands of cockroaches invading their property. The sighting of a few can be distressing and also lead you to wonder how many of these creepy crawlers actually are living and breeding in and around the home.

In NZ, three cockroach species are commonly found in homes and gardens, German cockroaches, Gisborne and Native Bush cockroach. Cockroaches are oviparous, which means the females carry the eggs outside of their bodies, this is called an ‘ootheca’ which is a sac filled with up to 50 eggs! They usually deposit their eggs where their food source is and they, can produce 6- 20 times over their lifespan. Being nocturnal, often you may not see them traipsing across your kitchen benches or breeding in dark places.

What brings them inside?

Food – anything laying around that is consumable or for cockroaches, preferably decaying!.
After they find their food source the female cockroaches seek an ideal habitat to lay their eggs.
Cockroaches have the ability to climb up most surfaces and disappear into tiny cracks and crevices, so when looking around your property check the following places:

Common places for cockroaches to lay their eggs:

1) Dark places, like kitchen cabinets, behind fridge’s
2) Below kitchen sinks
3) Roof void and under floor boards
4) Vacant/spare rooms
5) Rubbish areas inside/outside

– Inside, you may find them crawling around the bathroom or kitchen areas.

Gisborne Cockroaches:

– Are widespread in the North Island and upper South Island. This introduced pest from Australia likes to live outside mainly close to wood chips and bark. But when temperatures heat up or rain threatens their habitat, they migrate elsewhere.
– Typically come inside during extreme heat and also when it is wet.
– In the past three years, reports from homeowners, showed a dramatic increase of this species during the hotter months especially in February and March.
