lots of posters from the North say that.
Florida has insects - lots and lots of them - they also have snakes, alligators, and other things that don't do well up North.
WDW sprays (despite what they say) constantly. Off site doesn't. Even in a great hotel you might have a bug - this is Florida.
the water bugs (and yes they are another from of roaches) are BIG and I mean BIG - they live outside but they will come in to an open door or window to eat your food. they are very, very hard to avoid and even harder to kill. Since unlike most roaches they don't live in the building. they live outside.
sorry but Florida is a tropical area and will have bugs.
unless a place has rats or mouses - I will stay there. the rats and mouses can be killed quickly - this is just bad management. But to get rid of the water bugs - well you would need to move FLorida to the north. Sorry!!!!
