Cockroaches are incredibly hardy insects that can survive for long periods without food or water. They have been around for over 350 million years, before dinosaurs existed. Cockroaches can squeeze into tiny spaces, run quickly, and sense movement and vibrations with antennae and leg hairs. There are over 4,000 types of cockroaches worldwide, and New Zealand has a native species called the Kekerengu, known for its strong odor.
