Comes with one packet of water-soluble attractant packaged inside a foil pouch. Just empty the contents of the foil pouch into the trap and add water. Lured by the scent, flies enter through the yellow top cap and drown in the water.
Refill attractants are sold in single-use pouches, allowing the trap to be reused over and over.
No killing agents—insects die naturally.
Simple and economical to reuse and recycle.
