3 EPA Guidelines for the Safe Use of Insect Repellents  Verify that the product has an EPA approved label  Read the label before each usage  Use only as directed and against the insects listed  Keep it out of children’s reach *Most repellents or their vehicles have significant toxicity, if ingested!  Apply only to body sites listed *many have significant mucous membrane irritancy and would be more readily absorbed when applied to or around mucous membrane sites!
