Safe and Effective Varroa Mite Treatment Products in NZ

Crafted from premium 304 grade stainless steel, our queen isolation cage sets the new standard for durability and corrosion resistance in beekeeping equipment. 

Fits three full depth frames with either 33mm or 35mm end bars.

Applications:

1. Queen Breeding: Perfect for queen breeders to ensure optimal larvae age for grafting, facilitating superior queen production.
2. Varroa Control in Warmer Climates: Ideal for limiting brood production during winter months, effectively reducing varroa mite reproduction.
3. Increased Honey Production and Queen Management: The three-frame cage revolutionizes honey production. See the procedure below.

Benefits of using the 3-frame cage during the Honey Flow:

A. Eliminates the need for a queen excluder, resulting in increased honey yield.
B. Optimizes hive resources with less brood and more nurse bees available for honey gathering or ripening.
C. Significantly reduces mite reproduction with the decreased brood area.
D. Three good brood frames are enough to sustain the hive during a honey flow period of 8 to 10 weeks.
E. At the end of the honey flow, the 3 brood frames can be removed to make a nucleus colony with the old queen.
F. A queen cell or mated queen can be introduced to the production hive for requeening purposes.
G. The production hive can be vaporized with Oxalic Acid to kill virtually every varroa mite in the hive while there is no capped brood. Super cheap & efficient with InstantVap.
H. Start the Autumn (Fall) with zero varroa mites!
I. Alternatively, the 3 brood frames can be frozen to kill the varroa mites inside the cells then added to strong healthy colonies to clean up and re-use.

Specifications.

• 109mm inside width, 121mm outside width.
• 459mm long x 242mm high.
• The top cap is 484mm long.
• The air gap in the mesh is 4.3mm. Bees can take pollen through successfully.
• Has a clip-on cap which is held firmly down when the next box or hive mat is added above it.

Internal hive dimensions must be the Langstroth standard to ensure the cage fits properly and there are no gaps for the queen to escape.

Many beekeepers ensure their queens are marked so they are easy to find for caging when required. 

 One frame cage available here.

As we see more and more varroa resistance to the synthetic miticide strips, beekeepers are turning to organic acids for successful varroa control. There is no evidence worldwide of the mites getting resistant to them. The stainless steel cages are very resilient in an acid environment and will not oxidise and deteriorate like galvanised steel products.

It pays to get quality!

This large 304 grade stainless steel heated tank makes it nice and easy to liquify crystallized honey, or wax or anything that requires gentle heat!

The tank has an outer jacket which is filled with water or oil. The electric element heats the liquid in the outer jacket directly to provide a very safe and even heat to the contents inside the tank.

There are two size options to choose from: 
- 80 Litre
- 100 Litre

The tank can be heated close to 90 degrees. The tank has an outlet at the bottom. A ball valve comes as standard. You can also fit a honey gate, sold separately here.

The unit has an accurate and easy-to-use thermostatic controller. Adjustable from 30°C to 90°C where you set upper and lower limits. Simply set your upper and lower limit and the element will maintain the temperature between that setting. Once the jacket has heated to the desired temperature, the thermostat only supplies power to the heating element as it is needed to maintain the correct temperature.

Dimensions:- Both tanks are 510mm diameter plus any of the fittings on the side.  Height to the top of the tank:
80 Litre - 630mm.
100 Litre - 700mm

230 volt, 2000 watt.

Nassenheider Professional Evaporator - Advanced Varroa Control

Please order in multiples of 2 units. That is is how they are packaged at the factory, with 46 evaporators packed per carton. Please note: the evaporator is sold without 65% Formic Acid. Click here for Formic Acid.

Take control of varroa mites effortlessly with the Nassenheider Professional Evaporator. This long-term evaporation system is designed for safe and effective varroa treatment in beehives. Perfect for autumn (and Spring) varroa control, it utilizes a 65% formic acid (FA) solution for consistent evaporation over a 20 day period when using the No.2 wick. Beehives with high infestations can be brought under control in a relatively short space of time. In areas with high re-infestation issues, it is recommended to do 2 treatments. For treatments in summer or during a honey flow, we recommend using Oxalic Acid Extended-release (OAE) strips.

Key Benefits:

• Cost-Effective Varroa Control – A reliable, long-term solution that reduces expenses.
• Healthier Bees – Clients report reduced symptoms of chalkbrood and nosema after a 20-day FA treatment.
• Boosted Honey Yields – Stronger colonies mean better honey production.
• No resistance – Nowhere in the world have varroa mites grown resistance to these natural products - Formic Acid, Oxalic Acid or Thymol.
• Proven over many years – Europe have been treating mites with natural products for over 40 years.
• No residues – Formic Acid and Oxalic Acid leave zero residues in the comb.
• Less Sugar Feeding – Healthier bees naturally gather more food during the off-season.
• Simplified Safety – Easy-to-follow procedures minimize risks when handling formic acid. 65% FA is safer to handle than common off-the-shelf 84% FA.

Product Features:

• Complete Kit: Includes the evaporator, 250ml bottle, and three wick sizes for adjustable evaporation rates.
• No. 1 Wick: Very slow evaporation and suggested for use in Nucleus colonies.
• No. 2 Wick: Ideal for single brood box colonies, evaporating 250ml of FA in approximately 18 days. If filling the bottle to the top = 290ml and will last approx 20 days. 14ml/day.
• No. 3 Wick: Recommended for double brood box colonies. One of our tests in Jan 2025 showed 250ml evaporation in 7 days. 36ml/day.
• Versatile Design: The evaporator requires a 75mm spacer rim located directly above the brood box. 90mm top feeder rims or empty Supers can also be used.

Evaporation rates:

With 65% Formic Acid, it is recommended to evaporate between 9 and 22 mill per day per full depth brood box. 22 mill per day in one brood box is at a level where it is thought to disrupt the mites under the cell cap. But that high level of exposure is not necessary for good mite control. 14 mill per day will kill virtually all the phoretic mites. (Mites on bees) Drone cells are capped for 14 days so as long as there is an application killing virtually all phoretic mites for a continuous 15 day period then good varroa control can be accomplished.

Safety.

Formic Acid liquid, and the gas from the liquid, can damage skin and eye tissue. It is very important that suitable protective clothing is worn. It is especially important when filling bottles from the bulk supply containers. A respirator mask with face protection, nitrile gloves, PVC apron and overalls should all be worn. Replacing empty bottles with full bottles in the field requires nitrile gloves as a minimum. Stand upwind when doing this procedure.

Field-Tested Results:

In a Featherston field trial, where autumn varroa control was historically challenging, the Nassenheider Evaporator delivered outstanding results, significantly reducing mite levels and improving colony health. Read the full blog HERE.

Usage Tips:

• Assemble evaporator parts with desired wick size.
• Spread the fleece cloth in the tray and secure it with the clips provided. Double up the cloth at one end so the post for the bottle clamp is not covered.
• Fit the bottle holder onto the post.
• In an outdoor location and with suitable protective clothing, fill the bottle with 250mls of FA and secure the lid for safe transportation.
• At the apiary site, place the tray on top of the brood nest.
• Remove lid from bottle and screw on the evaporator while the bottle is vertical.
• Check the screw connection for tightness to ensure safe operation.
• Place bottle with evaporator into the bottle holder. See video for more info.
• Fit a 75mm rim to surround the evaporator. Fit hive mat and lid. 
• For creative beekeepers: Cut old full-depth boxes into three rims and paraffin-dip them for sterilization.
• Top Tip:- Extra bottles can be purchased separately here. Fill hundreds of bottles in a safe manner & location then fit them to the evaporators out in the field as required. The beekeeper is then exposed to very little FA and only needs to wear protective gloves. Very similar to handling Formic Pro pads.
• NB. If your beehive has a vented base, it is recommended to block the vents and leave the front entrance fully open for best results.
