i just thought others might be interested in a couple of recipes for DIY thymol based anti-varroa treatment and thymolated syrup for winter feed (good vs nosema and prevents mould).

Emulsified thymol pre mix (for syrup):

30g thymol crystals placed in honey jar,add 5ml of isopropanol to the crystals,place jar into a water bath of boiling water to speed up the dissolving process.
In another jar pour in 140 ml of boiling water and add 1 teaspoon of lecithin granules, stir well,and place this jar into a water bath of boiling water,stirring often for abot ten minutes or so until most of the lecithin granules have dissolved,you can then strain this mixture through a teastrainer or similar to remove any granules that have not dissolved fully,then simply add the dissolved thymol to this mix,and shake well,will look just like a jar of milk.
To use add 5ml to each gallon of syrup and stir well,syrup will go milky,unlike when using the old original mix.
If the mixture forms any crystals at a later date,tip into old small pan and reheat,do this outdoors.

Thymol/Oasis varroa treatment:

The mixture is 8 grams thymol to 12 grams oil,sunflower,rape,olive or even old chip oil,multiply this measurment to make more.

warm in old pan outdoors until all the thymol crystals have dissolved then add 20 ml of this mixture to a piece of the green absorbent garden oasis(not the grey one) this is the size of a sardine tin or half pound cut comb container. two inches wide, three and a half long, and 8 ml thick. put oasis in container then put liquid on, leave overnight to soak in,will soak in better if warm.

To treat bee's cut this in half and place the two parts on top of brood frames over the brood area. reduce entrance to about 2 inches and block of any feed holes,and mesh floors,give second treatment in two weeks and another 2weeks later.

I just move the previous treatment to the outside of the brood box on the edges,some bee's chew this right away to nothing others don't touch it some just nibble the corners,makes no differene as it still works really well.look at varroa floor the next day,mites will be dead. needs to be used in warmish weather and some bee's may hang out of entrance for a couple of days others take no notice,no bad effect on bee's or queens,helps to prevent chalkbrood, much more effective than apiguard.

I believe this was tested on around 5000 hives over a period of time in spain. nucs use half this dose. do not use when supers are on,can bee used on swarms as soon as queen stars to lay but before brood is sealed or if bad build up of mites in summer by doing artificial swarm and treating the broodless bee's for short time and parent colony until all young bee's have emerged and the mites killed.

possible variation:

I follow the recipe above with the only difference being I fold a Kleenex into 4 and add a single dose,then put into a plastic container(Curry size)and add a sheet of grease prood paper,I then do the same with the next Kleenex and so on. When I get to the hives I add one tissue per hive discarding the grease proof paper.

it seems a very strange recipe, some parts looks like magic potion.Rolling Eyes Why some ingredients as sunflower, rape, ect are foreseen for this mixture?

why the hive entrance has to be reduced?


How long do you treat the hives with these methods?

Ciao Davide - the oil is simply a vehicle/solvent for the thymol which allows you to soak the necessary amount into the oasis.

you use 3 treatments of a fortnight each.(so 6 weeks total)

entrance reduction etc is just as one uses for any thymol based treatment - maximise the vapour in minimum space.

What is the benefit of lecithin added by whether it is useful to bees?

thanks

Scusate ma č un forum Italiano o Inglese? Perche' non tutti capiscono e magari avrebbero l'interesse di farlo, di solito č l'ospite che fā lo sforzo per farsi capire dalla collettivitā...

Sorry but it is a forum Italian or English? 'Cause not everyone understands and maybe would have the interest to do so, it is usually the guest who makes the effort to make themselves understood by the community ...
