Cockroaches are unwanted guests in homes, generally living undisturbed and with plenty of food. They are found most commonly in damp and filthy dwellings, in which they can multiply enormously. Cockroaches are omnivores, but prefer plant material containing starch or other sugars. When coming in contact with food, they can transfer various disease organisms. The female produces up to eighteen egg cases about once per month, each containing around fourteen eggs. The nymphs hatch after roughly two months and take approximately a year to mature. In nature, cockroaches are scavengers, consuming various sorts of debris and rotting organic material.
