Using Enoz Moth Ice Crystals On Stored Wax Frames

(1/4) > >>

Jen:
As usual I froze all my wax frames this Fall for storage. By golly some of my frames have wax moth larvae wiggling around on them... grrrrr. So I've heard of using Enoz Moth Ice Crystals during winter storage. One way of application is to stack 3 boxes, each box filled with 10 frames. Place a paper plate with 3 tablespoons of ice crystals under the stack of boxes. Put the lid on the top box. Leave them like that until you are ready to use them.

Anyone know about this method?

What is the active ingredient?

 Para-dichlorobenzene (PDCB) is an insecticide used in beekeeping for wax moth control. Analysis of PDCB residues were carried out on Swiss retail market honey samples by the cantonal food control authorities in 1997, 1998, 2000, 2001 and 2002. 173 Swiss honeys and 287 imported samples were analysed. On average, 30% of the Swiss honeys contained PDCB, 13% of them being above the Swiss tolerance value of 10 mug/kg. On the other hand, only 7% of the imported honeys were contaminated. The minimum values were 2 mug/kg, the maximum ones 112 mug/kg. Long-term monitoring of Swiss beeswax, carried out from 1993 to 2000, showed that most of the comb foundation beeswax produced in Switzerland is contaminated by PDCB with values ranging from one to 60 mg/kg. The results show that the reason for this contamination is the use of PDCB for the control of wax moth. These residues can be avoided as wax moth can be controlled successfully with alternative methods, carried out according to good apicultural practice.

I use that method.  Instead of a paper plate I use newspaper and put the moth crystals right on the newspaper.  You have to be careful to purchase the correct moth crystals as Iddee and RAST are pointing out. Enoz changed their packaging about 2 years ago, making it more difficult to identify the correct product.  Para-dichlorobenzene is the ingredient to look for, like RAST said.  When in doubt, Mann Lake sells Para-Moth. You will be sure you are getting the right ingredients.  https://www.mannlakeltd.com/para-moth-1-lb-454-g-canister
I also noticed when Enoz changed the packaging, the price when up a lot.  Ounce for ounce, the Para-Moth probably costs the same now.

I am curious Jen.  Were those brood frames or honey super frames?  I know a long time beekeeper that says wax moths attracted to the pollen in the brood frames so they are not interested in honey supers.  I am not sure I agree with him.
