Threehoney Varroa Mite Counting Boards for 10-Frame Hives — 6-Pack Adhesive Checkerboard Sheets, Trim-to-Fit

Threehoney's 6-pack varroa mite counting boards are adhesive monitoring sheets sized for 10-frame hives, designed to slide under screened or solid bottoms to help you track mite drop over 24 hours.

Monitoring Varroa levels is a regular part of hive management; these disposable glue boards give a fast, visual record of mites and debris beneath the brood chamber. Each sheet is printed with a high-contrast checkerboard pattern that makes tiny brown mites easier to spot against a light background, and the pack includes six full-size boards so you can rotate, replace, or trim them as needed.

How do I use a Threehoney mite counting board in my hive?

Using the board is straightforward: peel the protective film, place the adhesive side down under the screened or solid bottom, leave it in place for a monitoring interval (commonly 24 hours), then remove and count mites visible on the grid. Boards fit 10-frame hive footprints and are easy to trim for different bottom sizes.

• Peel protective layer and insert adhesive side down under hive.
• Leave for the chosen monitoring period (24 hours typical).
• Remove and use grid contrast to count mites and debris.
• Record counts to track trends or treatment timing.

What size and material are these counting boards, and can I modify them?

Each board measures roughly 20.08 × 14.96 inches (51 × 38 cm) and is made from rigid cardboard coated with an adhesive surface. The substrate is sturdy enough for insertion and removal yet simple to trim with scissors so it fits nonstandard bottom boards.

• Full-size fits standard 10-frame hives out of the box.
• Hard paper core provides rigidity for handling.
• Adhesive coating captures mites and debris for clear counting.
• Trim-to-fit so it works with screened or solid bottoms.

Why does the board have a checkerboard pattern and how does it help me count?

The colored grid creates contrast against the brown Varroa mites and hive detritus, making individual mites easier to spot and tally. This visual aid speeds up inspections and reduces counting errors, especially when you compare consecutive monitoring results to gauge infestation trends.

• High-contrast squares simplify visual detection of tiny mites.
• Patterned layout supports quick counting and documentation.
• Use repeated counts to monitor population changes over time.
• Works on both screened and closed bottom setups.

How many are included and what should I expect from the pack?

The set contains six adhesive boards sized for 10-frame hives, giving you enough supply for multiple checks or seasonal rotations. Because they are disposable, you can replace a soiled board without cleaning, and having several on hand makes routine monitoring quick and consistent.

• Six boards per pack for repeated monitoring cycles.
• Disposable design keeps inspections hygienic and fast.
• Extra boards let you schedule regular checks without interruption.
• Small surface imperfections in the adhesive film do not affect performance.

Who is this for: These Threehoney counting boards are aimed at backyard and small-scale beekeepers running 10-frame hives who want a simple, low-cost way to monitor Varroa mite drop. They suit anyone who prefers visual, grid-based counts for routine surveillance, needs replaceable monitoring sheets, or wants an easy-to-trim option for nonstandard bottoms. They are not a treatment tool but a diagnostic aid to help you decide when further management steps are needed.
