Insects have a uniquely frustrating way of finding their way into homes. To ensure you're always protected from flying insects like fruit flies, flies, and moths, replacement glue cards are an essential item to have. The StickyTech Replacement Glue Cards fit any trap in the DynaTrap Flylight Trap series and come with 6 replacement cards in each package. To increase the efficiency of the trap, it is recommended each card is replaced as needed or every 30 days. The StickyTech Glue Cards are a powerful tool to use against flying insects. When in place, the glue cards are hidden behind the trap's decorative cover so they never compromise your decor.
