Stay away from any sort of scented soap, body lotions, etc. When putting on Off or Cutter, have the kids strip down and spray them all over with a good layer, let them run around a bit in the room to let it air dry. Put on swim suits and spray the suit too. Sounds crazy, but you sit in the sand and bugs don't care if they bite your butt or your legs. Don't spray the face, but spray your hands and then rub necks and ears.
