Perizin
Towards the end of the year, when there are no longer any brood in the colony, is the right time to treat the hive with the varroacide Perizin® (active ingredient: Coumaphos). This treatment destroys the entire mite population, helping to prevent problems in the spring. Perizin® can also be used to determine the initial extent of the mite infestation. Indeed, just performing the test constitutes half of the treatment.
Very practical: the test.
A single treatment with Perizin is sufficient to determine the extent of the infestation with Varroa mites. Prior to treatment place a clean sheet on the bottom of the hive and check it one day later. If you find dead mites on the sheet, the diagnosis is clear. In this case, you should treat all the colonies in the apiary twice at one week intervals.
Incredibly easy: applying the treatment.
You can prepare the ready-to-use emulsion for trickling on the bees using the handy set. Trickle 10 – 50 ml of the solution, depending on the size of the colony. That’s it. The rest of the work is done by the bees themselves. They consume the emulsion and spread it by social feeding contact throughout the entire colony. The active ingredient enters the bees’ hemolymph through the digestive tract. And when the mites feed on the hemolymph they get a deadly dose that kills them off.
Highly safe: the effect.
The amount of active ingredient consumed by the bees is not dangerous to the bees themselves, but is enough to kill the mites. When using Perizin it is important that the outdoor temperature is not lower than +5 °C, because this can lead to excessive cooling of the bees resulting in death. In general, a modest mortality rate of roughly 50 bees can be expected when Perizin is used, as long as the colony is not too old or already seriously damaged. Normally, this level of mortality does not pose a threat to the colony. Perizin is also well-suited for use with new colonies shortly after they have formed.
Perizin.* Active ingredient: Coumaphos. For animals: bees. Composition: 1 ml solution contains 32 mg of Coumaphos (0,0’-Diethyl-O’’-(3-chlorine-4-methyl-7 cumarinyl)-thiophosphate). Area of application: for diagnosing and combating (therapy) varroa mites in bees. Contraindication: Perizin may not be used during foraging periods. If used in spring, the therapy must be completed six weeks before foraging begins. Do not use for treatment when the temperature is below +5° C. Side effects: Perizin is a medicine specifically for bees, which has been optimized in extensive laboratory and field trials to be effective and compatible. At the recommended, no side effects can be expected. However, the treatment can cause a few bees to die at low outdoor temperatures. This is caused by bees getting wet and then excessively cooled and will not impair the development of the colony as a whole. Special precautions to be taken by the person administering the product: Perizin is for external use only and may not be ingested by humans or other vertebrates. Avoid direct contact with skin, mucous membranes and eyes. If there is accidental contact (mucous membranes, eyes) rinse thoroughly with water. Wear protective gloves when using the product. Do not eat or drink when using the product. After handling the product, wash hands thoroughly. Keep out of reach of children. Antidote: When using appropriately there is no danger of intoxication. In case of poisoning inject atropine sulphate 1% solution i.m.. Dosage (man): 0.2-0.5 ml. Repeat injection of atropine sulphate when action of atropine dimishes and the poisoning symptoms (pupil contraction, muscle trembling, vomiting, diarroea) worsen. Waiting period: 1. The waiting period between the diagnostic or therapeutic use of Perizin and the start of foraging flights amounts to six weeks or 42 days. 2. If used less than six weeks before the start of foraging, the honey then obtained may not be used for human consumption or fed to other bees. Sold only by pharmacies.
