These little bugs love me as well!!! A good rule of thumb that my mom told me was that they come out most the hour before and after sunset. So if I am going to be on the beach during this time I will make sure I put bug spray (More deet the better) or I will try to stay in the wet sand or water.

Now with kids I would guess that you can't keep them in one area, so many try to make sure you have bug spray on them about an hour before sun set.... Always worth a try.

I have also found that over the years that the amount of sand fleas vary. I feel some years I get bite a lot and other years not at all. I usually travel to Negril around the same time of year.
