Oxalic-glycerine strips for varroa treatment are becoming more and more popular as beekeepers look to better long-term, eco-friendly methods of fighting this pest. As varroa becomes more resistent to synthetic treatments, oxalic acid is proving a consistently reliable option.
Large commercial beekeepers have been using OVA board/oxalic-glycerine strips for varroa treatment for several years now. They have cut treatment costs by up to three quarters while still maintaining low varroa levels.
Beekeepers Friend Strips are:
- Developed specifically for using with oxalic/glycerine treatment.
- Manufactured in the USA by the same company who also makes OVA board.
- Made from a lighter more absorbent material than OVA board therefore they are easier to insert in your hive.

A commonly used solution is 4-6 ratio by volume of oxalic acid to glycerine. Dissolve the oxalic acid by heating the solution. Place strips in a large bin or other plastic container and leave to absorb the solution. Dry the strips before using in the hive. There are quite a few You-tube video’s available showing how to do this, including the following from Kirwee Bees: https://youtu.be/eY8mqvKrY40?fbclid=IwAR28AdJNr-OSOdK2m0fYzgV-hxGffTr2pbw9Uag5YN48Lj_LYW9UKTAbm8w
It is essential to test a few strips on a couple of hives to ensure you have the correct mixture to be effective without harming your bees.
