We've been to Florida recently, and I *have* to add Mosquito's to this list! We'd ran into them on other trips of course (mostly while out camping) but the Florida kind seemed especially evil. Not only do the bumps they leave itch 100 times worse than the local variety, they also sting very painfully!
Pro of this last feeling is that you know you have been stung & can retaliate, con is that the damage is already done.... itchy itchy itchy.
Oh, and whatever we used to spray on us as bugrepellent, NOTHING seemed to work
Before we came to Houston I read up a little on the dangers while out caching/camping and so far I've managed to stay clear of PI and other dangerous plants/animals.... if only we could eradicate all chiggers & mosquito's all would be well in the world!
