Use insect repellant. If you’re going to be outside for any length of time, you really should use insect repellant. The Centers for Disease Control’s Vital Signs report shows that the incidence of diseases caused by mosquito, tick and flea bites more than tripled in the U.S. from 2004 to 2016. Since the Environmental Protection Agency regulates insect repellants, the Environmental Working Group (EWG) recommends using an EPA-registered repellant. EWG researchers found that, with proper application and precaution, the ingredients Picaridin, DEET and IR3535 effectively reduce risk from disease and have very low toxicity concerns.
