Oxalic acid has a 97 percent efficiency rate, and applying it does not require you to open up your hive. Oxalic acid is a naturally-occurring acid found in many foods such as chocolate, beets, spinach, and peanuts. It gives such food a slightly bitter taste (think: dark chocolate). It also naturally occurs in hives, so, if used as directed, this acid will not harm any bees!
Oxalic acid will not control varroa mites in capped brood, so it's important to treat over the course of several weeks as the brood hatches. Use in late fall and early spring to minimize amount of brood present. There are three different methods of treatment. Make sure you follow directions exactly. Do not have honey supers on when you treat!
