We also tried the mosquito bracelets and discovered the same thing...... the mosquitoes ignore them ! They might stop the mosquitoes from landing right where the bracelet is, but even if you put one on each arm and leg, I don't think that they would keep the mosquitoes away.
We also got one of those light bulbs that has a bug-zapper built in and put that on the front porch instead of the regular front porch light; but we didn't have any mosquitoes attracted to that light either.
Since the mosquitoes came right inside the house if we left the door open, we finally started using one of the citronella candles right at the entrance to the house, and that seemed to work as well as anything.
When we were outside in the yard, the mosquitoes were so thick and vicious that even wearing mosquito repellant didn't help a whole lot. We had some really tiny ones; but they were seriously persistant.
