These cockroaches are usually looking for warm, moist, dark places to call home. Cockroaches, by design, are survivors. They are nocturnal , making them hard to spot. If they are discovered, their flat bodies make it easy for them to escape into small crevices. Their antennae and cerci help them detect changes in vibrations and air pressure, making it difficult to even step on them.
Cockroaches are omnivorous .
They eat anything from dog food to plaster. Internal bacteria help cockroaches digest these unusual meals. If necessary, cockroaches can live for three months without food and one month without water. Although cockroaches preen regularly, they are still suspected of transmitting diseases such as salmonella, dysentery, and typhus. They are also suspected of causing allergic reactions in half of the 17 million people afflicted with asthma.
