RTU=Ready To Use! No more mixing, no more math, just dead mites.
Looking for an easier alternative to vaporizing oxalic acid or mixing your own dribble with sugar syrup? Api-Bioxal RTU “Ready-to-use” removes the math and mixing, leaving you to just treat your hives. RTU is a better version of oxalic acid dribble created without a sugar syrup base, meaning the oxalic acid will stay active in hives longer. This shelf-stable formula can be stored at room temperature for at least 1 year, even after the bottle has been opened. This is because the formula contains no sugar, which can form toxic byproducts during storage and also tempts the bees to eat the treatment. 0.5 liter (500mL) contains approximately 10 treatments.
When to use: Best when colonies are broodless, but also allowed to repeatedly apply to colonies with brood, similar to repeated oxalic acid vaporization treatments.
How apply: While wearing appropriate PPE, measure 5mL of ready-mixed solution, and then dribble directly onto the bees by squirting it between the top bars in each box. Only apply to seams between frames that are occupied by bees. A single application treats broodless overwintering colonies, swarms, packages, and other broodless colonies. Repeated applications permitted when brood is present, 7-10 days apart, up to 4 applications.
Make applying RTU even easier by pairing with Alveis'Dosa-Laif Dribble bottle to quickly measure and dribble RTU in seams of bees.
