A clip-on mosquito repellent from Skeeter Hawk: a carabiner holding a repellent puck, supplied with two replaceable pucks. Clip it to a backpack, belt loop, pram, camp chair or fishing bag for personal protection without sprays or lotions on the skin. The pucks release a blend of natural essential oils, geraniol, lemongrass oil and citronella oil, which Skeeter Hawk says is more effective than citronella alone. Each puck lasts about 30 days, so the pack gives about two months of use before refills are needed. Handy for hiking, gardening, sports days and evenings at the braai. Keep the spare puck sealed until you need it.
