Flowtron GB470 Adhesive Fly Board 12-pack 18 in

What the boards do and who needs them

The Flowtron GB470 adhesive boards replace the sticky surface in compatible fly traps. Each pack contains twelve transparent sheets measuring 4 1/2 by 18 inches. They are intended for homeowners or businesses that already own a matching trap and want a simple, chemical-free way to catch flying insects indoors.

Practical limits of the adhesive surface

The boards rely on a passive glue layer that captures flies on contact. Once the surface is covered with insects or dust it loses effectiveness and must be discarded; the product is not reusable. Performance drops in very humid or dusty environments where the adhesive can degrade faster than expected.

Installation and common issues

Each board slides into the trap’s guide rails without tools. A frequent problem is misalignment that leaves gaps where flies escape. Another issue is accidental removal of the protective liner before the board is seated, which causes the adhesive to stick to the trap housing instead of the insert.
