I bought this today at Bunnings thinking it could be used to trap queen ants. It's meant to attract insects with a UV light and then a fan pushes them into a tray full of water with some detergent to break the surface tension to make them drown. I'm thinking maybe without detergent or without water it could be applied to trapping queen ants instead.

The light is about 8W I think but with the reflectors it still shines pretty brightly, and I remember reading somewhere it was 365nm but I can't find where that was so it might have been a different product.
Let me know what you think
