How Can I Prevent Insect and Spider Bites?

DEET is the principle and most effective insect repellant. It is found in a variety of readily available products. There has been some concern about the negative effects of using this chemical, particularly for children, but none of the "natural plant" products (see below) are likely to be as reliable.

Essential oil of eucalyptus (eucalyptus globulus) is a natural insect repellent. Make a solution by adding five drops to a cup of water, and dab on your skin. Essential oil of citronella discourages insects when placed on exposed skin. A few dabs of calendula (calendula officinalis) ointment on the face, arms and legs may keep insects away. It is also available as a commercially prepared product.
