    Check Randy Oliver's site. But remember, if you measure your thymol syrup in Milli-moles, he will claim you are not a beekeeper( a comment I took personal).

    Thymomite from Heilyser Technologies is a fine product. It is a strip impregnated with 12g of thymol. Add 1 strip on the top bars, 2 weeks later a second one. Treat when temps are below 90F. works pretty good. Price is reasonable.

    You can also add 2 tsp of thymol in the lid of a honey jar. You need a screen of sorts place on the lid to keep the bees from removing the thymol. You would also need an inner cover o there is sufficient room to place the thymol. the bees tend to want to propolize the screen to seal the thymol vapours.

    I have tried the former method and not the latter.

    Larry,

    My understanding is that Thymol is a “membrane disruptor”. To me this is like putting soap or salt on an open wound. Mites and insects have soft connective tissue around moving parts that are susceptible.

    There are some commercial applications on the market and some homemade applications too.

    I intend to use 1 drop Thymol per ounce of FGMO and see how it works.

    I will second that. Bees will tend to propolize it at times but when the conditions are right it's a pretty effective treatment. The big advantage thymol has over Formic is that you aren't "on the clock" before it quits working. Even after an extended period of cold weather, in which few mites are being killed, all it seems to take is a little warm weather to activate it again.

    I will third the comment on the strips fro hieslyer.

    My personal experience, first year we had bees. 24 hr sticky board count turned up one mite. We debated treating at all, but we had strips, so put them in. 24 hours later another count. I lost track of the count somewhere north of a thousand from that same hive.

    Year one, all hives survived. Year 2, we put strips into 6 hives. Similar drops, and all survived. This year we put them in all the hives. We put two strips in a double deep, one in a nuc. Two applications on two week spacing.

    Are the strips the reason we have had 100% survival when everybody around us is losing hives? I dunno, but not going to try going without them to find out.

    Interesting side note, our bees haul them out in the spring.

    I am also thinking about using a cup of this mixture and soaking paper towels in a zip lock bag then put the paper towels under the inner cover for a lingering effect. The bees will eventually chew it up I think and remove it.

    Several years ago a beek from another country was soaking cord (soft rope?) in FGMoil with thymol. Put several inches of rope into hive. (I'll have to search and re-read about it.) I'm also thinking a soft treatment might be beneficial and easier on the hive. We've tried thymol in syrup, no negative effects, didn't notice positive either. Plain FGMO really starts the hive humming, so this might be important part of treatment success. I'll post again if I find the information.

    Thymol with fog doesnt work for mites. If it would have worked, many would be using it.

    Use blue shop towels.
    12 gr thymol plus 18 gr vegtable oil for each towel.
    Multiply by number of towels you need. ( 2 towels per hive )
    Use 1 towel 2 weeks apart. Leave the fist towel in the hive when you add the second.
    Done this for 5 years now.
    Works great. Not to many losses. Around 15%.
    Run 300 hives now.

    Hi Bear's Treasure,
    What kind of thymol do you buy? Do you have a link? I see all kinds on line and at amazon, but I'm not sure what to buy.
    Thanks,
    Robbin

    We have good success with using Api Life Var, which is tymol based product.

    It comes in a small biscuit that you break into four pieces, and place on the top bars. You do this for four weeks and then check for mite numbers.
