Raid Family Guard Electric Mosquito Diffuser with a 30-night refill. This Raid unit combats both common and tiger mosquitoes, helping your family enjoy a quieter night’s sleep. The diffuser is thoughtfully designed with children in mind, providing a steady shield over the room when protection is most needed. Its 2-in-1 action repels mosquitoes inside the space and also reduces the chance of them entering. We all want our loved ones to rest without pesky insects interrupting them. One refill delivers around 30 nights of protection when used for eight hours per night. The device’s level indicator makes the remaining liquid easy to see: swap in a new refill as soon as it’s empty.
