The large fly trap by Skeeter Hawk effectively attracts, traps and kills fruit flies, gnats, drain flies, house flies, horse flies, moths, June bugs, no-see-ums, mosquitoes and thousands of other flying pests. Dual band LED UV light attracts them, while the whisper quiet fan sucks them in where they dehydrate and die. The large fly trap effectively protects larger backyard spaces, around pools and large patios. The foldaway hook and long cord, allow for versatile placement. For complete protection against mosquitos (which when hungry, hunt by detecting the CO2 we breathe out) be sure to wear some form of repellent, like our essential oils wearable tabs. For best results, place the large fly trap outdoors, away from your patio, windows, and doors in order to attract pesky bugs away from gathering areas. It is recommended that you empty the trap bin weekly during the spring and summer months and monthly during the fall and winter months.
