Kate, Apivar strips are the most effective way of treating a hive. OAV is a safe and natural alternative that performs almost equally as well when applied properly. Oxalic acid is not a toxic chemical, unless you happen to be a varroa mite, it is found in a huge number of foods we eat. Of course any substance can cause one harm, including water, if used incorrectly and without proper precautions.
