Nantucket Spider natural, DEET-free bug spray is a highly effective mosquito repellent that is also effective against ticks and biting flies, including blackflies, deer flies, greenheads and horseflies as well as no-see-ums. Nantucket Spider repellent is a water-based blend that contains essential oils of rosemary, rose geranium (effective at repelling ticks), citronella and lemongrass for repelling mosquitos, clove bud oil, cedarwood oil, peppermint and lemon eucalyptus — (do be sure to test a patch of skin for allergy sensitivity before use!). Because it is water-based, it is not greasy. It can be sprayed on skin and in hair and can be sprayed on clothing and gear without staining or damage. The lockable trigger sprayer ensures full coverage and superior application of product — the product goes on as a light mist that covers fully rather than a dribble or stream that overly wets some surfaces and misses important spots. Nantucket Spider smells great too! We think you will agree that our newly patented repellents are the best natural bug sprays you have ever tried!
