Dry Wall Shim for oxalic treatment x 300

Description

Hive World supplies Dry Wall Shim for oxalic treatment:

• Dry Wall Shim for oxalic treatment comes as cardboard strips in bundles of 300.
• Measuring 38mm wide by 393mm long. This gives a cost of 9 cents per strip
• Soak strips in a solution of glycerine https://www.hiveworld.co.nz/product/glycerine-food-grade/ and oxalic acid.  Once they have drained, you then hang the strips over your brood frames.  (This is the same method as with regular varroa treatment.)
• We recommend a 40-60 ratio by volume of oxalic acid powder to vegetable based glycerine.
• Heat the solution gently to dissolve the oxalic so there are no crystals remaining but take care not to heat it over 60 degrees Celsius.
• Do not use an aluminium pot as the acid can react with the aluminium.
• Place the strips in a plastic pail or bin preferably with a lid and then pour the prepared oxalic mixture over to cover the strips. Leave strips submerged until they are completely soaked through.
• Remove strips and store until required.
• Use four strips per brood box and leave for 6-8 weeks.
• Check strips after 4 weeks as the bees in a strong hive can remove them and they may need to be replaced.
• Please Note – By law we are not allowed to sell ready-made oxalic/glycerine strips.  However, there are instructional videos and plenty of advice available on their manufacture.
