I especially want to get the thyme oil into them. Thymol is reported to repel the dreaded varroa mites. It is also effective against tracheal mites. How does it work? The bees ingest the syrup containing the EO's (essential oils). They also feed it to the larva.The mites go to feed on the larva and are repulsed because they taste like thyme. The key is to feed the bees enough EO's to dissuade the mites but not enough to harm the bees. After some Googling I determined that I would need 5 drops of thmye oil and 10 drops of sweet orange, peppermint and lemon grass oils per quart of 1:1 sugar syrup. I need to get a calibrated syringe but for now shaking out the drops will have to do. I dosed up a fresh quart of syrup and set it out for the bees this morning. It smells very fragrant and I was wondering how the bees would react to it. No worries, they love it.
Just before dark this evening.
