Our Mosquito-Free barrier solution creates a Mosquito-Free Zone for your family and friends to have a complete, mosquito-free outdoor experience. Our Mosquito-Free solution is guaranteed to kill mosquitoes on contact. Furthermore, it adheres to foliage, repelling biting insects for three weeks. For maximum effectiveness, the Mosquito-Free barrier solution is applied by our state-certified technicians on a 21 day schedule. Once our solution is applied, we recommend allowing it to dry for 30 minutes before you are ready to enjoy your very own Mosquito-Free Zone.
