Each box contains 3 monitoring stations with the ability to monitor for 3 months with each. One kit of 3 to be used per field 4ha and under. Over 4ha they should be placed every 50 meters around the crop, utilising prevailing winds, etc. Set traps at 1.5 meters high. Stapling the foot of a pigtail standard to the top of a fence post on a slight angle works well. Monitor traps are only as effective as the ability to check them regularly.
