Fly Trap Medium is an ecological and effective trap for catching flies and it is very easy to use. Fly Trap Medium does not contain insecticide or other chemical products, so it is suitable to be used in eco-friendly activities. The attractant is composed by a mixture of protein meals and other specific natural essences for flies. A single post can capture up to 20.000 flies. Fly Trap Medium is ideal for the use in gardens, farmsteads, agritourism, food factories, kennels, little domestic livestock, etc. The trap remains active for 60-90 days circa. The bait envelope contained in the trap is water-soluble. After 4-5 hours it starts to develop its attractive power, which reaches its greatest effectiveness after 3/4 days. Fly Trap Medium must be placed outdoor, where adult insects fly and where it get more daylight hours as possible. In warmer weather (T >32°C) we recommend to place the trap in the shade.
