Formic Acid (65%)

Formic Acid is a powerful, naturally occurring treatment used to control Varroa mite populations. Unlike many other treatments, it has the unique ability to penetrate capped brood, targeting mites where they reproduce. This 1-litre bottle provides a versatile option for beekeepers who prefer to calibrate their own liquid applications.

• Pro-Tip for Northern Ontario: Temperature management is vital when using Formic Acid. It is most effective when daytime highs are between 10°C and 25°C. In Northern Ontario, this window often occurs in late spring or during the "post-harvest" period in August. Always ensure the hive has plenty of ventilation during treatment to help the bees regulate the fumes safely.
