If you’re a beekeeper looking for an effective way to control Varroa mites in your hive, you may want to consider using an oxalic acid vaporizer. This guide will show you how to make your own vaporizer using readily available materials, so you can save money and treat your bees more easily. Oxalic acid is a natural substance that is safe for bees when used properly, and vaporizing it is an effective way to kill mites without harming your bees or leaving chemical residues in the hive. By following these simple steps, you’ll be able to make a safe, effective oxalic acid vaporizer and keep your bees healthy and productive.

Oxalic acid is a natural substance that can be used to control varroa mites, a common parasite that can weaken and kill honeybee colonies. Vaporizing oxalic acid is an effective way to treat a hive, and building your own oxalic acid vaporizer is a cost-effective solution. Here are the steps to make a simple oxalic acid vaporizer.

Materials Needed:

  • Stainless steel or copper pipe with a 2-inch diameter
  • 12-volt battery charger (at least 5 amps)
  • Stainless steel or copper wire
  • Electric drill with a 3/32-inch drill bit
  • Solid copper wire or copper tubing
  • Oxalic acid
  • Respirator or mask with filter

Step 1: Prepare the Pipe

The first step is to prepare the stainless steel or copper pipe. Cut the pipe into a 4-inch length and drill a 3/32-inch hole into one end of the pipe. This will be where the oxalic acid crystals are inserted into the pipe.

Step 2: Make the Electrodes

Next, make the electrodes that will be used to vaporize the oxalic acid. Cut two pieces of stainless steel or copper wire, each about 2 feet long. Wrap one end of each wire around the pipe so that it forms a tight coil around the outside of the pipe. Make sure that the coils do not touch each other, as this could cause a short circuit.

Step 3: Attach the Electrodes

Attach the electrodes to the pipe by securing them with solid copper wire or copper tubing. Make sure that the coils are positioned so that they are facing each other and are about 1 inch apart. You can use pliers to bend the wire into shape and secure it to the pipe.

Step 4: Connect the Battery Charger

Connect the battery charger to the electrodes by attaching the red clip to one electrode and the black clip to the other electrode. The battery charger should be set to 12 volts and at least 5 amps.

Step 5: Insert the Oxalic Acid Crystals

Insert 1 gram of oxalic acid crystals into the pipe through the drilled hole. Use a funnel or a piece of paper to pour the crystals into the pipe. Make sure that the crystals are evenly distributed around the pipe.

Step 6: Connect the Battery Charger

Connect the battery charger to the electrodes by attaching the red clip to one electrode and the black clip to the other electrode. The battery charger should be set to 12 volts and at least 5 amps.

Step 7: Vaporize the Oxalic Acid

Place the vaporizer in the hive, preferably on the top bars of the brood box. Make sure that the vaporizer is not in direct contact with the bees or the comb. You can use a piece of wood or other material to prop up the vaporizer so that it is elevated above the bees. Turn on the battery charger and allow the vaporizer to heat up for about 2 minutes. You should see a small amount of smoke or vapor coming out of the vaporizer. Once the vaporizer has heated up, turn off the battery charger and let the vaporizer sit in the hive for about 10 minutes. The vaporized oxalic acid will spread throughout the hive and kill the varroa mites.

Step 8: Remove the Vaporizer

After 10 minutes, remove the vaporizer from the hive and allow it to cool down. You can use pliers or gloves to handle the vaporizer, as it will be hot. Make sure that you dispose of the oxalic acid crystals properly and follow any safety guidelines recommended by your local authorities.

Important Safety Tips:

  • Always wear a respirator or mask with a filter when handling oxalic acid crystals or using a vapor
