SkeeterVac mosquito traps are brought to you by Blue Rhino, a leader in the outdoor living industry. Mosquitoes track down hosts by sensing carbon dioxide (the primary cue), moisture and heat from breath, body odors and color contrasts. SkeeterVac mosquito traps create a combination of those cues. This tricks the insects into thinking the trap is a host. Then it finishes off the job by trapping and eliminating those biting pests so your outdoor experiences are safer and more enjoyable.
