KATCHY Duo Glue Board Refills — 8-Pack Replacement Sticky Pads, Fits Duo Model, Long-Lasting Adhesive

These are eight replacement glue boards engineered to fit the KATCHY Duo indoor insect trap, delivering long-lasting adhesive capture for small flying pests.

If your KATCHY Duo trap needs refreshed sticky pads, this 8-pack gives you ready-to-use boards sized specifically for the Duo model. The pads feature a high-tack adhesive designed to trap tiny fruit flies, gnats, and other small flying insects for up to four weeks per board under normal indoor conditions. They’re simple to install and remove, letting you maintain continuous protection without replacing the whole unit.

How do I replace a glue board in the KATCHY Duo?

Swapping a used board for a fresh one is quick and tool-free. Open the Duo’s base, set a new glue board into the tray, peel off the protective cover, and reassemble the unit.

• Lift the Duo trap’s bottom tray to access the adhesive slot.
• Place a new glue board flat in the compartment, aligning edges.
• Remove the backing film just before closing so the adhesive stays pristine.
• Dispose of full boards by sealing them in a bag before trashing.

What insects will these refill pads trap and how long do they last?

The glue boards are optimized for very small flying insects commonly found indoors, such as fruit flies and fungus gnats. Each board’s formulation keeps its tackiness for weeks, with typical use lasting up to four weeks before replacement is recommended.

• Effective against fruit flies, gnats, small moths, and similar pests.
• Designed for indoor home and kitchen environments.
• One board typically remains effective up to 4 weeks depending on infestation level.
• Replace sooner if the surface becomes covered in trapped insects.

Are these glue boards compatible with other KATCHY models?

These refill pads are custom-sized for the KATCHY Duo only and won’t fit the Katchy Original, Automatic, or Pro models. Using the correct board ensures a snug fit and optimal contact with flying insects as they enter the trap.

• Compatible: KATCHY Duo model glue tray.
• Not compatible: Katchy Original, Katchy Auto, or Katchy Pro units.
• Using the wrong pad can reduce trapping performance and may not seat properly.

Who is this for? These 8-pack glue boards suit anyone who already owns a KATCHY Duo and wants a convenient stock of replacement pads to keep the trap working continuously. Ideal for kitchens, fruit bowls, indoor plants, and other areas where small flying pests gather, they’re a practical option for renters, homeowners, and small businesses looking for a low-effort way to manage nuisance flies without chemical sprays.
