Wonderjune 2-Pack 10-Frame Solar Fume Boards — Classic Wooden Hive Caps with Felt Reservoir for Easier Honey Extraction

The Wonderjune 2-pack 10-frame solar fume boards are wooden, felt-bottomed hives caps that use sunlight to vaporize applied hive-safe treatments and encourage bees to vacate the honey super for easier extraction.

These classic-style solar fume boards combine a felt drug reservoir with a corrugated black top panel to capture heat and diffuse treatment vapors gently through a 10-frame honey super. Built from wood, glued and nailed for durability, each board measures about 20.08 x 16.14 x 1.18 inches (51 x 41 x 3 cm) and comes in a two-piece set so you can service multiple hives or keep a spare on hand.

How does the solar fume board work to clear bees from the honey super?

The board’s felt underside soaks up a small amount of evaporation treatment (applied in a zigzag or X pattern) and the black corrugated top captures sunlight, warming the treatment and encouraging slow vapor release into the super below. That gentle vapor acts as a temporary repellent, prompting bees to move down into the brood chamber so you can remove frames with less disturbance.

• Apply medicine evenly in an X or zigzag across the felt base for consistent evaporation.
• Place the board corrugated side up directly on the topmost honey super for best heat capture.
• Sunlight warms the black top, releasing vapors over time without mechanical devices.

What are the materials and build quality of these Wonderjune fume boards?

Each board is constructed mainly from wood with a felt-lined bottom and a black corrugated plastic top panel. The boards are glued and nailed for reinforced edges and long-term use; the felt holds treatment while the outer surface withstands sun exposure during typical extraction days.

• Wood frame for structural strength and longevity.
• Felt base absorbs and holds small doses of treatment securely.
• Black corrugated surface maximizes solar heat absorption for steady vaporization.

How do I use and maintain the two-pack during a honey harvest?

Using the Wonderjune fume board is straightforward: apply the recommended treatment pattern to the felt, set the board on the honey super with corrugated side up, and allow sun exposure to release vapors. After use, clean residuals from the felt and store boards dry to preserve felt absorbency and wood condition.

• Coat felt in an X or zigzag with a small recommended amount of treatment—do not oversaturate.
• Place board during warm, sunny hours for most efficient vapor release.
• Dry and store indoors to prevent moisture damage to felt and wood when not in use.

Will these boards fit my hive and how many do I get in the pack?

These Wonderjune boards are sized for 10-frame universal hives and measure roughly 51 x 41 x 3 cm, making them compatible with most standard 10-frame supers. The package includes two boards so you can treat two supers at once or keep a backup for frequent extraction days.

• Designed for 10-frame universal hives—measure your super if unsure.
• Two boards included for simultaneous use or spare rotation.
• Compact, classic profile fits under most outer covers or shallow transport lids.

Who is this for: The Wonderjune 2-pack solar fume boards suit hobbyists and small-scale beekeepers who want a low-tech, reusable method to reduce bee presence in honey supers during extraction. They’re ideal for keepers who prefer non-powered aids, need durable wooden tools, or run multiple 10-frame colonies and want an affordable two-piece solution to streamline harvests.
