This all-natural flying insect repeller/after bite remedy is made with a blend of 8 essential oils and organic catnip (which is about 10 times more effective than Deet, with the toxicity) to effectively repel mosquitoes, black flies, wasps, no seeums, midgies, fleas and ticks. The lemony/herbal scent is calming and pleasant to us bit irritating to flying insects…so they leave you alone. The clear plastic vial has a spill proof “rollerbar” applicator for easy and clean application. Just roll it on the exposed areas on your skin such as your wrists, neck and ankles. The formula is highly concentrated and a little goes a very long way. If you forget to roll it on and get bitten, apply the roll on over the bite as soon as possible. It will calm or prevent itch (depending on the time lapse) and avoid a welt. Safe for kids and the dog too. You will be pleasantly surprised.
