Ian I would caution you to approach an OA dribble in the spring. This is definitely a task for the boss. Bees coming out of the building are old and tired and OA dribble essentially tires them out. I understand the need to use an alternative treatment but...
One season in the fall, I had one foreign employee who probably applied more than the recommended dosage ( I can't keep watching them all the time, cause I got work to do) and come next spring the line of pallets he did were pretty much wiped out. So instead of bees on the ground I had inprints on the grass of where the pallets used to be. I cannot be sure but I think he overdosed them. He is no longer with us.
soon as I get a great idea in my head, I hear a story like that which put me back into that "I dont know what to think" area...
paint Stick of traz in the entrance keeps mites down for 40 cents/ hive x 3 spring= $1.20. Then a fall oa dribble and good nutriton in the fall seals it up. But of course its no longer appropriate to mention such treatments now adays even thou it has worked well for the last 12 years.

That being said, you had shown me the proper way to administer the OA dribble. It's helped keep the mites at bay. I like the apivar though. I think after a treatment with apivar you could almost go through the whole year with out using anything else.
I wonder though, If I'm treating in late summer early fall with apivar in my double broodnests, is it still advisable to put 2 strips in the top? It doesn't make much sense since the top box is all honey. I would think that 2 strips in the bottom box, where the last of the brood is being reared, would be sufficient rather than 4 strips per double.

The label says to use 1 strip for 5 frames of brood(FoB) or less, to use 2 strips for 6 to 10 FoB, 3 strips for 11 to 15 FoB, and 4 strips for greater than 16 FoB.
I had surgery last early summer, and didn't get to do too much with my hives. I know it was late to be putting Apivar or any kind of treatment on the hives in October but I had a kind friend to come on a warm day and put Apivar on them. In less that the recommended time, the weather turned COLD, and couldn't get into the hives to take out the strips. They were taken off this early spring and not a mite to be found. I have four hives that were treated, and three VSH hives added. Would it be good to rotate treatment with Apiguard or do another this fall with Apivar>Thanks so much!!!
treat is your threshold is met, but as you say, no mites found in the spring, so Im guessing the levels will be low by fall
I'm sorry....are you saying, rotate Apivar with Apiguard this fall?????
Not a safe assumption to make Ian. Just because one doesn't find any when they check in the Spring, however they check, that doesn't mean there are Zero mites in the hive. Just that they were not detected. Check again the same way and you might find one or two.
By Fall, three or four months later, those mites have gone through as many brood cycles as the bees have and you can have a level detrimental to the colony's ability to last the Winter.
So, if you don't treat unless you determine that the mite load warrants it the only way to know whether that level has been met is to check again early enough that a treatment can be applied.
I have been very impressed with Apivar and the colonies I treated last fall still have no mites on them. Just checked today. However, some folks have been trying to convince me to use an Australian medication, and given the cost, it might be worth it.
How do you check? What method?
I assumed because usually when there is a very low mite pop in the spring, they cnat muster any devastating levels by fall, assuming that the testing method was accurate.
I use a shaker, and survey many hives. I like this method of testing as it seems to be gather enough information from the hives to form an accurate picture.
When I usually treat in the spring with Apivar, I usually dont treat the following fall.
chickenia, what kind of testing are you doing when determining "no mites"?
I get these Apis mixed up. Apigaurd is the gel, right? Apivar is the strip? Apilife var is a wafer?
I used the strips starting in late March and leaving them in until after apple pollination was over. a little longer than the prescribed time. I haven't check any myself, but an Apiary Inspector checked some and found mites. I forget how many in each sample, but the average was 9. That's more than I have had when I didn't treat in the Spring. what's up w/ that?
i dont like the sound of that...
