B&G Matrix II Four Seasons Fly Light comes with standard non-shatterproof bulbs.
The glueboards are positioned in the back of the Matrix II Four Seasons Fly Light. The lights in the unit are what attracts the flying insects. Be sure to place the fly light away from competing light sources.
Flylights such as the B&G Matrix II Four Seasons Fly Light are designed to be used inside where light sources can be limited and would not be recommended outside. Results would be limited due to the outside competing light but in a barn if doors/windows can be closed it could work. You could use a Dynatrap Indoor/Outdoor Insect Trap indoors or outdoors.
