The active ingredient of Api Bioxal, i.e. oxalic acid, is very effective against Varroa mites in the phoretic phase. Various studies on the mechanism of action of oxalic acid suggest that its low pH was found to be the main factor responsible for the acaricide.

We can conclude by saying that the oxalic acid acts by contact.
