Varroa Treatments

Varroa Treatments

Varroa Treatments:  We recommend Oxalic acid.  This is a reliable and eco-friendly varroa treatment for your beehive.  Varroa mites do not build up resistance to this naturally occurring product therefore you can use it constantly. (That is, apart from when the  honey flow is on).   It is also an economical method to use.

There are two ways of applying oxalic acid to your hives.

Firstly:  By sublimating oxalic crystals using a vaporiser/sublimator inserted into the hive.  We supply both a commercially viable treatment device – the Sublimox – as well as an economical option for the hobbyist – the Vapmite.  Hive World sells Oxalic Acid in 350g and 750g jars for economy and convenience.

Important Note:  Remember, Oxalic Acid is a toxic and corrosive substance that can be harmful to health.  During the filling of your devices as well as during  treatment it is essential to wear a face mask, gloves and long sleeved clothing.

The second method is to place strips in the hive that have been soaked in a mixture of oxalic acid and glycerine.  This is similar to using the chemical treatment strips.  You have to place strips in each hive and then remove them after 8 weeks.  Beekeepers are responsible for making their own oxalic acid/glycerine mixture.   This is because we are not legally allowed to sell impregnated strips.  However, we sell the strips all ready cut for you to use.  BKF strips are specially manufactured for this purpose in the USA.  OVA board (a building product) is another material that is suitable for purpose.

Important:  Always check your strips on one or two hives to ensure you have the correct ratio of oxalic/glycerine.

Regular chemical treatments:

We also stock bayvarol strips and apivar as another option to hit the mites.  This powerful combo provides a double whammy to knock out the mites.    By using these treatments alternately every 6 months you help prevent the varroa from building resistance to either of the chemicals.

Whatever method you choose, the important thing to remember is to regularly check your hives.  Keeping an accurate varroa count means you can hit them when the numbers rise.  Use the sugar-shake method to check the numbers.   Keeping a corflute board underneath your ventilated hive base enables you to keep an eye on the varroa drop.
