Choose Safer® brand houseplant sticky stakes as an alternative to synthetic pesticides. Houseflies, including whiteflies, blackflies and midges aren’t just an annoyance. An infestation of these small winged pests can rapidly wreak havoc on your houseplants. Flies breed fast and to reduce damage to your plants, you need a solution that works quickly to nip an infestation in the bud. Chemical pesticides are an option but may fill your home with an odd smell or be hazardous to small children or pets.
