The Dynatrap Indoor Insect Trap is labeled for pests are would likely be attracted to UV light and CO2. Wasps would likely not go into this light.   We would recommend using the Trappit Wasp Bag Trap. Simply hang in a location which is away from people (e.g. the furthest corner of a garden) and leave for 4-6 weeks or until the bag is completely full of dead wasps. In hotter seasons, water can be added to the bag if it becomes dry to re-activate the ingredient. Once full, screw the top closed and dispose of in the ordinary waste disposal. The innovative entry system means escape is virtually impossible once inside.
