Are you ready for a safer way to treat your hives for varroa mites without the hassle of mixing your own dribble solution or using a vaporizer? Api-Bioxal RTU (Ready to use) takes all the guesswork out of oxalic acid dribble treatments. This premixed formula eliminates the need for sugar syrup and delivers consistent results every time.

Unlike traditional homemade mixes, Api-Bioxal RTU contains no sugar, meaning the oxalic acid remains active longer inside the hive and doesn’t encourage bees to consume it. The result is a more effective and stable treatment that’s safe for bees and simple for beekeepers.

This shelf-stable formula can be stored at room temperature for up to 3 years sealed, and even 1 year after opening—a major improvement over homemade mixtures that spoil quickly or lose potency.

Available Sizes:

• 500mL: approx. 10 treatments

• 1L: approx. 20 treatments

• 5L: approx. 100 treatments

When to Use:
Ideal for broodless colonies but can also be applied repeatedly in colonies with brood—similar to multiple vaporization treatments. Apply up to four times per colony, spaced 7–10 days apart.

How to Apply:
While wearing proper protective gear (PPE), measure 5 ml per seam of bees and dribble directly between the top bars of frames that are covered with bees. A single application treats broodless colonies, swarms, and packages.

For quick and accurate dosing, pair with the Dosa-Laif Dribble Bottle—the perfect companion tool for Api-Bioxal RTU.
