Detalles de Paperboard strips (for vaseline)

Monitoring natural varroa drop is the first step in deciding whether to treat or wait. These 1.75 mm laminated cardboard strips slide into the mesh floor of the hive, coated with petroleum jelly, to trap mites as they fall through. After 3–7 days you pull them out and count — a simple, cheap method that requires no colony manipulation.

🌿 Laminated card + petroleum jelly: the right pairing

Unlike solid cardboard (which works better with water), laminated card holds petroleum jelly evenly on the surface without absorbing it. The adhesive layer stays active for several days, trapping every mite that drops without being dislodged by wind.

📐 Standard size for mesh floors

At 305 × 38 mm, it fits the most common mesh floors on the market. The 1.75 mm thickness gives enough rigidity to slide into the floor slot without bending, yet it is disposable and low-cost — ideal for routine monitoring throughout the season.
