EZ-OX Oxalic Acid for Bees – 5 lb Bucket, Bulk EPA-Registered

EZ-OX Oxalic Acid for Bees – 5 lb Bucket (Bulk)

Bulk oxalic acid for honey bees, for the yard that treats by the pallet, not the hive. The 5 lb bucket is 2,268 g of the same EPA-registered EZ-OX we sell by the bag — 97% oxalic acid dihydrate, no sugar carrier, made in Cambridge, Ohio by Mike's Bees, a veteran-owned company (EPA Reg. No. 101743-2). It is the cheapest legal way to put oxalic acid through a vaporizer.

The math for a commercial yard

• 2,268 g per bucket — 567 treatments at the label rate of 4 g per deep box, or over 1,100 at the 2 g per box we recommend and run ourselves.
• About 10 cents per dose. $109.99 ÷ 1,134 doses. Api-Bioxal at $54.99 per 350 g is about 31 cents a dose, so a 100-hive series costs you roughly $14 in acid instead of $44.
• One bucket covers a 100-hive summer series. Seven rounds at 2 g across 100 hives is 1,400 g, with 800 g left for the fall and broodless winter treatments.

Why this acid

• EPA-registered and labeled for use with honey supers on. Legal in every hive you run.
• Burns clean at volume. No glucose or silica excipients, so a chamber cycling every 10 to 25 seconds all day stays clean instead of building a charred deposit that changes how the acid heats.
• Works in any vaporizer. InstantVap, ProVap, Varrox Eddy, or whatever is on your truck. In a yard of this size we run the InstantVap Turbo — about 10 seconds per 2 g dose, with a cycle counter so a crew never loses its place.
• Made in the USA by a registrant you can call. Not a repackaged import with no label.

Vaporizer dose

• The label: 4 g of powder per deep brood chamber, and 4 g per deep box is the maximum legal dose.
• What we recommend: 2 g per brood box — a single deep gets 2 g, a double deep gets 4 g. It is the dose most of our customers have run for years, and why the InstantVap plunger adjusts from 1 to 4 g. Step up to the full 4 g per box for a heavy infestation.
• Seal the entrance, vaporize, keep the hive closed for 10 minutes.
• Vapor reaches mites on adult bees, not mites under capped brood. With brood present, a spaced series across a full worker brood cycle is what catches them as they emerge. The Treatment Series Planner builds the schedule for your hive count and totals the grams.

Storage

Resealable pail. Keep the lid on and the bucket dry; oxalic acid dihydrate is stable for years sealed. Decant into a smaller container for the truck rather than opening the pail in the field.

Safety

At commercial volume, PPE is not optional. NIOSH-approved respirator with acid-gas cartridges, gloves, eye protection, and stay upwind of the entrance. We use the PD-101 full-face respirator. Procedure: how to use an oxalic acid vaporizer safely.
