RT @SDFighttheBite: When choosing an insect repellent, pay special attention to the Active Ingredient. For effective protection against mosquito and tick bites, you want an active ingredient that has been proven to work, like DEET, Picaridin, IR 3535, or Oil of Lemon Eucalyptus. https://t.co/vfMU13Bk5p via @SDCountyHHSAMore
