TICKS

Tiny little monsters

Contrary to popular opinion, ticks are not in the insect family, but are in fact arachnids. They are known for transmitting a number of different diseases and infections. People who spend a lot of time outside have an increased risk of being bitten by ticks – so they need strong, long-lasting, and non-irritating protection. In 2008, a study by Scott Caroll showed that products containing the active substance IR3535® have a long-lasting effect against ticks (Ixodes scapularis). After just a single application, a 10% lotion provided protection for nine hours, a 20% pump spray worked for twelve hours, and a 20% aerosol provided reliable protection against ticks for 11 hours*.
