I find that they are attracted to the light of the skylight. When we get gnats/mosquitos on occasion, the easy to be rid of them is to remove the screen from the bath fan, turn the fan on its highest setting and turn on the light in the bath... shut off all others lights in the camper and leave the bathroom door open for a good hour or so... attracted to the light and without the screen the gnats will be sucked out when attracted to the area... be sure to leave the entry door or a window open to maximize airflow.
