about these things. I was telling my friend we're going to go to Sanibel/Fort Myers area for a few days before our cruise and she said just watch out for the no see ems . I mean of course you can't see them, but I just mean how can I prevent from anyone getting them and ruining a few days of vacation because of them?? She said there is a "florida swamp spray" stuff you can buy. Is this some thing that I need to WORRY about??
