Per the label for spraying packages.


>SPRAYING PACKAGE BEES
Ensure bees are clustered before applying oxalic acid (for example store in cool dark location 24 hours before application).
Spray broodless package bees with a 1:1 sugar: water solution at least 2 hours before spraying with oxalic acid. This allows bees to fill honey stomachs with sugar water reducing the ingestion of oxalic acid.

>Mix a 2.8% oxalic acid solution by dissolving 35 g of Oxalic Acid Dihydrate in 1 liter of 1:1 sugar: water (weight: volume). Evenly apply 3.0 mL of 2.8% oxalic acid solution per 1,000 bees using a pump sprayer or battery-powered sprayer (for example, a typical 2 lb package contains approximately 7,000 bees which require 21 mL of solution). Apply the solution evenly on both sides of the package.
