Worth a try
Size: 1 Count (Pack of 12)
Not perfect protection, but fewer mosquitos in the past two weeks. I use them in my study where I'm most likely to sit still -- one down low on my desk chair (reduces ankle bites), one on a door knob, one on a corner of my desk. I don't wear them often because I find them uncomfortable. Can't report yet how long they last. Odor is not overwhelming or unpleasant.

Buggy Bands for a camping trip
Size: 1 Count (Pack of 12)
Because of my experience with bugs loving me and using similar buggy bands to ward them off, I purchased these Buggy Bands for an upcoming camping trip so I can enjoy the great outdoors without the side effects of the bugs.
