Selecting An Insect Light Trap
Wall Mount, Ceiling Hung, or Portable?
Place wall mounted ILTs down low to best catch day-flying insects like the housefly. It is the fly's nature to be below five feet high (even skimming the floor) when they are most responsive to ILTs. Generally speaking, the lower you place a trap, the more responsive flies will be to it.
Ceiling-hung ILTs are the trap of choice for night-fliers. They have a tendency to fly at higher heights in buildings. However, night-fliers exhibit a more intence, relentless response to light than day fliers (think bugs around a porchlight). Night fliers and day fliers can usually be handled with a well designed system consisting primarily of low, wall-mounted ILTs. See Strategic Installation for exceptions.
