Cockroaches

1. Overview

Cockroaches are large robust insects with whip like antennae and two pairs of wings. They have long slender legs which makes them elusive runners and difficult to catch. Cockroaches lay their eggs in little purse shaped cases. These can sometimes be seen projecting from the abdomen of the female.

The most common species found in the UK are the Oriental and German cockroaches.

German Cockroach

The German cockroach is light brown or tan in colour. It is 12 – 15 mm in length. The egg capsules of German cockroaches contain up to 32 eggs.

Oriental Cockroach

The oriental cockroach is shiny and blackish brown. It measures between 18 to 29 mm in length.

The oriental cockroach deposits her egg case soon after it's formed in an area where the young can find food. The egg case contains around 16 eggs.
