The Acana Moth Monitoring Trap uses advanced pheromone technology to attract moths to the unit, where they get trapped on the sticky board, providing immediate and visual evidence of an infestation. This trap serves as a first alert for an infestation and can be used to monitor the effectiveness of moth killing treatments. We recommend using Acana Carpet and Fabric Moth Killer Spray as a treatment for adult carpet moths, eggs, and larvae. The large 100sq cm surface area of the sticky board ensures effective trapping of any carpet moths or beetles present. The trap also comes with a Timestrip visual end-of-life indicator, which shows when to replace the sticky board.
