As the bloodseeking insect reaches the attractant tube, it realizes it can't get
a blood meal. Because the mosquito will not turn down (insect behavior) and it
won't fly across the plume of carbon dioxide (overstimulation), it is forced to
turn upwards, where it's caught in the vacuum of the suction tube. At this point
it is vacuumed into a net, where it dehydrates and dies within 24 hours.
