Increase during the more temperate climates in Auckland when outdoor roach varieties seek warmth indoors. Girborne and American types are often spotted in and around the home in search of warmer areas. Especially in the cooler seasons they may find shelter in under the weather boards of a home, they often congregate around the entry way or porch. Often they can be observed in the laundry, bathroom, and general living areas. The indoor German or even Asian roach will mostly be an issue around hot water cupboards and almost always in the kitchen, favoring appliances like the dishwasher, fridge, and microwaves. The German Roach is very populous in Auckland, much like the larger roaches they too enjoy the warm humid climate. They often nest solely inside and are the only type of cockroach to predominantly co-exist with humans. This roach, unlike the larger variation do not seek food far from the nest, their hierarchy and nest order is quite unique and present difficulties in their control even by professionals. These cockroaches often will nest in concealed spaces and an established nest can be persistent in multiplying and difficult to exterminate. Modern insecticides have been developed to help combat the nesting habits of this pest.
There are many types of cockroaches, but there are three types which mainly come into contact with us in our homes and commercial buildings.
