Mosquitos are bad here in GA, and they just did a test of the most popular brands on one of the local news stations. The clip ons were "ineffective" while the Cutter Deep Woods Scentless was the best of the batch with regular Off almost as good. The separating factor between the two was scent. They are also good for repelling ticks. The other "natural" ingredient repellents that has eucalyptus and other things in them were alright for mosquitos, but didn't last as long and had zero effect on deer ticks. Don't know if there's ticks in Belize, but the way I see it, if there's mosquitos, there's probably ticks, and I'm more worried about them anyways.
