Essential Oils - Hygiene in Beehives

Varroa control and Mould prevention    -    New 1.25" Thymol tablets 

Thymol kills more than 90% of the mites                                                    

The advantages of Thymol tablets:   - easy to use - high efficacy - no resistance - does not pollute - organic product.

Ingredient:    100% Thymol, more than 99.6% pure           Chemical Class:    Essential oil
Method of Application:  Thymol has been applied to beehives world wide by various methods; strip, crystal, powdered and liquid Thymol are used. 

Thymol pressed as a tablet for an easy measuring, can bee applied in a beehive without using a spacer and provides a controlled release of vapors. 

Treatment 

5 frame nuc = 1 Tablet, 1 deep super = 2 Tablets , 2 deep supers = 3 - 4 Tablets, two or  three weeks later the same amount again, without removing the first.
Applications can be made in any time, when conditions are suitable. All applicable restrictions must be followed. Thymol should not be use when surplus honey supers are in place.
Thymol should be used in spring and late summer, when temperatures are above 15ºC / 59ºF. Do not use Thymol at temperatures above 33ºC / 90ºF. For best effect - daytime 15º-25ºC / 59º-77ºF, without falling below 12ºC / 54ºF for long periods.
Screened bottom should be closed while Thymol is being applied. Reduce entrance to approx 15 cm / 6 inches.

Mold prevention  -  New 1.25" Thymol tablets 

During winter month pollen in combs not occupied by the bees, become mouldy. To prevent mould from growing in your hives, a Thymol tablet is the option. 

Treatment 

Applying a premeasured dose of pure crystalline Thymol tablets to your hive will prevent mould fungus from damaging the combs and pollen.  Thymol tablets should also be used to protect stored combs with and without pollen outside the bee colony.

Chalk Brood  

The disease is characterized by the infected brood, called ‘mummies’ so named by their appearance. Larvae die of chalk brood after the cells have been capped. 

Young larvae usually die within a couple of days of having been sealed in their cells, otherwise they die as pupae. 

Chalk brood is a infectious fungal disease which is caused by Ascosphaera apis and which appears to be on the increase. Only the larvae of Apis mellifera are particularly susceptible and Ascospaera apis does not multiply in adult bees, it will weaken a colony and reduce honey yield by up to 30%. 

Spores are highly infectious and carried in contaminated pollen by infected foraging bees with spores left at floral and water sites, drifting bees and drones. Ascospaera apis is ingested by the bee larvae with their food. 

It is known that Ascospaera apis grows best when the brood is chilled, and the correct temperature within the brood box is an important factor in limiting infection. As the disease has a limited ability to spread, most transmission occurs through the activities of beekeepers – exchanging equipment and bees, feeding contaminated honey and using contaminated tools and gloves. 

You should also ensure that you are using a high-quality syrup which is free from mould spores. 

The use of a ventilated floor can also help to reduce both humidity and condensation. It may also be worth considering moving your hive to a location with more sunlight and less moisture. 

Some people also consider replacing the queen, as she may be transferring the fungus throughout the hive. 

Treatment 

Very often, no method of prevention is sufficient to remove a chalk brood problem. If this is the case, then you need to apply a treatment to the hive to ensure that the fungus disappears. 

The currently available treatment option is to apply an premeasured dosage of pure crystalline Thymol to your hive and let it vaporise. This essential oil acts as an antibacterial and anti-fungal agent.

Stonebrood 

Stonebrood is a fungal disease caused by Aspergillus fumigatus, Aspergillus flavus, and Aspergillus niger. It causes mummification of the brood of a honey bee colony. The fungi are common soil inhabitants and are also pathogenic to other insects, birds, and mammals. 

The disease is difficult to identify in the early stages of infection. The spores of the different species have different colours and can also cause respiratory damage to humans and other animals. When a bee larva takes in spores, they may hatch in the gut, growing rapidly to form a collar-like ring near the head. After death, the larvae turn black and become difficult to crush, hence the name stone brood. Eventually, the fungus erupts from the integument of the larva and forms a false skin. In this stage, the larvae are covered with powdery fungal spores. 

Worker bees clean out the infected brood and the hive may recover depending on factors such as the strength of the colony, the level of infection, and hygienic habits of the strain of bees.

Treatment 

The only available treatment option is to apply an premeasured dose of pure crystalline Thymol to remove this fungus.
