Sometimes called a roly-poly, the pill bug (Armadillidium vulgare) is one crustacean that spends its entire life on land. Its ability to roll itself into a ball when threatened has helped it earn the titles of roly-poly and pill bug. But some gardeners call it a pest. In large numbers, they can do considerable damage to flowers, seedlings and tender plants. Fortunately for gardeners, natural ways to deal with them do exist, including essential oils.

Essential Oils for Pill Bugs Several essential oils have shown to be effective against troublesome pests including pennyroyal oil, peppermint oil, eucalyptus oil, cinnamon oil, citrus oil, citronella oil, rosemary oil, oregano oil and tea tree oil. Oils of cinnamon and oregano are particularly effective against pill bugs. These oils work best added to natural biodegradable soap. If spraying on bugs directly, use four drops per gallon of soapy water. Organic therapeutic grade oils are preferred.

Other Pill Bug Controls Pill bugs can also be controlled in other natural ways. Cayenne pepper sauce, chili pepper oil, garlic spray or garden-grade diatomaceous earth can be used to safely battle the pill bug. Garlic spray is made with 1 Tablespoon of crushed garlic per quart of water. Mixing diatomaceous earth with pepper sauce or garlic oil makes a powerful natural pesticide. Predatory nematodes are also helpful. Pill bugs may also be trapped using apple cider, vinegar or whiskey.
