26. Has Apivar participated in residues trials, and what were the findings? Yes. The French agency for Food, Environmental and Occupational Health Safety, has conducted residue trials on Apivar strips and found that: No active ingredient residues were detected in honey after 10 weeks of treatment, regardless of the date of sampling. Others studies also proved that, in honey, the active ingredient is fully degraded after 10 days. No active ingredient residues were detected in beeswax 24 hours after the removal of the strips from the hive. Amitraz does not accumulate in the honey and wax because of its instability in the hive’s acidic environment where it is quickly broken down by hydrolysis.
Similarly, other studies concluded that residues of amitraz or its main components in honey consistently fall below maximum residue limits established by the European Medicines Agency.

From this I assume that by spring traces of amitraz will be gone.
