Application:
Prior to treatment, remove all honey supers, close or replace open or screened hive
floors with solid floors, and reduce the hive entrances to normal size.
It is recommended that part of the feeding is carried out before the treatment, if the
infestation of varroa and the temperatures allow.
Begin
st
application of a treatment by placing appropriate number of beehive
strips (positions shown in Figure 1) on top of combs of the brood chamber (upper
brood chamber if two). Beehive strips should be close to, but not directly over open
or sealed brood (preferable distance > 4 cm).
Close the hive, leaving space (about 5 mm) between the beehive strips and the hive
cover to improve the evaporation of thymol. Do not place plastic cover foils directly
on the beehive strips.
Remove the 1
st
set of depleted beehive strips after 3-4 weeks.
Begin the
nd
application immediately with a new set of beehive strips in appropriate
numbers and positions, as shown in Figure 1. Remove these beehive strips when
they are depleted at the end of the 2
nd
3-4 week application period.
Do not treat with the veterinary medicinal product more than twice a year.
AN: 02352/2024 & 02353/2024
Do not use when the maximum daytime temperature is above 30 °C as this leads to
increased stress and mortality of adult bees and brood.

slight, during the treatment at high temperatures (above 30°C).
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See the immediate packaging
for respective contact details.
Reduced product efficacy occurs if average temperatures fall below 15 °C during the
treatment. Best efficacy is achieved when maximum daytime temperatures are
between 20 °C and 25 °C throughout treatment.
The efficacy may vary between colonies due to the surrounding conditions
(temperature, reinfestation etc.). The veterinary medicinal product should therefore
be used as a treatment amongst other within an Integrated Pest Management
programme, and mite drop regularly monitored. Colonies with an average mite drop
of more than 1 mite per day two weeks right after the last treatment must be
subjected to an additional winter or spring treatment for varroa (preferably with
another active ingredient).
AN: 02352/2024 & 02353/2024

Special precautions for safe use in the target species:
Treat all hives in an apiary at the same time to avoid robbing behaviour. Never place
beehive strips near a sugar feeder as this may reduce feeding.
If the sugar feeding begins to stagnate during the product application, the colonies
can be fed before the 2
nd
application in the following sequence: Finish 1
st
application
by removing the beehive strips after 3 weeks, then place the sugar feeder into the
hive and finish the feeding before inserting the beehive strips for the 2
nd
application.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Avoid contact with skin and eyes because of possible contact dermatitis and irritation.
In case of skin contact wash thoroughly the affected area with soap and water. In
case of eye contact wash the eyes thoroughly with copious amounts of clean running
water and seek medical advice.
When handling the product, wear impermeable gloves as well as the usual protection
equipment.
Special precautions for the protection of the environment:
Not applicable.
Other precautions:
Do not treat during honey flow to avoid potential taste tainting.
No data available.
Store below 30 °C. Do not refrigerate or freeze. Protect from frost. Protect from direct
sunlight.
Honey: zero days.
Do not use before and during the collecting period of the bees (honey flow) to avoid
residues in the honey. Do not extract honey from treated brood chamber combs in
the following spring.
