Pill bug is a woodlouse species that rolls up into an armour-plated ball when threatened. It is found in gardens and houses.
To trap pillbugs, simply place cabbage or potato peels under a clay flowerpot in your garden. Every few days, harvest the bugs that have congregated under the pot. Place them somewhere else, such as the compost pile where they can work as decomposers or dump them into a bucket of soapy water.
The first potatoes were cultivated in Peru about 7,000 years ago.
