For medium-frame brood chambers, use half the dose — two medium boxes stacked count as one deep box.\u003c\/p\u003e\n\n\u003ch2\u003eDetailed Description\u003c\/h2\u003e\n\u003cp\u003eVarroxSan is made from oxalic acid dihydrate (18.42%) in slow-release fiberboard strips. It works best in summer and fall, though it can be used year-round under the right conditions. The slow-release format reduces the need for repeated treatments — well suited for low honey flow periods when you don't want to keep opening the hive.\u003c\/p\u003e\n\n\u003ch2\u003eStorage \u0026amp; Shelf Life\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStore below 86°F (30°C), out of direct sunlight.
