    Im in this field.
    There is a substrate out there that has been patented in the US and other countries that has proved successful.
    Randy is well versed with them.
    They are designed to go between the frames just as normal strips do.
    One reason Shop towels and similar devices fail is that they are not placed in the broodnest .
    They are on the top bars.
    In the case of a double broodnest the shop towel is more effective because it is sometimes in the center of the brood nest.
    Any shop towel that is placed in a single brood nest hive and is in a damp climate will grab moisture and slow a marginal hive down.
    Probably the best device for carrying OA/GL is the Marco tape laminate.
    This device is a multi layer paper laminate that is connected with multiple rows of thread stitch.
    The rows of stitch present a barrier to the Bees attempts to remove the paper from the Hive.
    This device when put through the US patent system was one of the fastest patents in US history to go from filing to Acceptance for granting.
    7 weeks then a further 4 weeks for granting.
    Note. The word "Marco" is only used as a descriptive term that describes the type of paper used and is not used as any sort of branding term.
    The device is made using a Marco company paper Drywall jointing tape.

      Thanks so much for this information. I will check into it. I found the shop towels didn't hold much liquid, and dried out. The water absorbent pads work if there is room for the bees to walk on the top of them. If the lid fit down tight they didn't seem to work

      @@harrisjoubertwithsleepycre1924 Dear Harris thank you for you time in replying to my comments....... Latest I just gotta broadcast it from 50 odd per day drop in a month down to 3 today. This strip method I see has been around a bit? You are very experienced beekeeper and must have an enquiring mind as well as perception regarding knowing what's best for your bees.
      Incidentally but quite important is the fact that after 3 weeks I replaced the strips with three new ones and the low count still happened. I would think that this proves that if the 'old' strips had depleted when the fresh ones were inserted the mite count would have got UP....... I have the luxury of being able to count the drop each day.
      I'll keep a close watch in the coming days....... One thing is noticeable as opposed to last year= there is an explosion of worker brood and as Randy says the successful hives treated with the strips, have been his strongest ! Than you so much for advising what you find. Excellent.

    Thanks for the reply and your experiences which are a great help and give us confidence.
    The mixture 1 to 1 is potent. It burnt a hole on the wifes 'Marigold' washing up gloves. Probably rubber? I will pick them up with stainless forceps in future. What is surprising is that a lot of you experienced beekeeper say it doesn't hurt the bees. That is amazing and surprising to me. Are bees feet immune to acid?
    The quite modern RNAi idea is taking too long to be publicised used in a trial by Barry Hart who seems to be a very big professional who is all over the states.
    Finding out all there is to know about the new ideas is like the secret service and especially when it is so serious a subject like eradicating varroa mite.... I mean who needs those damn things which seem as bad as anthrax was way back.

      Good job the varroa are not so tough. The count is starting to go down and the Buckfast bee numbers are going up! Ain't it nice when something goes right?
      Incidentally, when I bought the bees there was no mention of mites. The mention of them might have prevented a sale?
      VSH bees and Buckfast too (supposedly) are said here in the UK to have been imported from Germany by a professional beekeeper & yet the direct message is that the EU will not export bees to the UK due to the strict/ hassle re the customs.

    Thanks for the informative vid. Just as a matter of interest my wife bought some fibre cloths made in Holland called Multy. They are thin but stiff enough to thread down the frames! They are 2mm gauge and about
    16 x 12". I cut mine into 2-1/2 inch x 9-1/2 strips. I notes that after 2 fumigations of OA the mite drop was 20 a day for a week. After one day the mite drop after putting the strips in it was 120. day by day it reduced to 18 a day! I feel this method is more efficient than the 4 gram fumigation.
    I only found out cuz I watch Randy Oliver who said this method seems very promising and seems to work well when the strip is between the frames?
    I do not know here in the UK if this method is legal? If it's not then why is spraying /drizzling oxalic acid onto the bees legal? This is how it is. My pal who said these folks in the States are about ten years in front of us lot
    in the UK and that was a great many years ago.
    He emigrated to the USA about 40 years ago but his uncle had been there 20 years before him.....

    Hello Harris, I am a cheap skate, I found out what the chemical for the synthetic varroa strips was and simply bought the active ingredients bulk from farming stores, some mathematics and bits and pieces and made my own strips. Tau fluvinate > Mavrik, flumethrin > Bayticol and animal tickacide > amitraz. I know
    Thanks for sharing you work with OA strips, from what I understand formic acid is way worse to use and can kill not only varroa but queens
    What is the go with this Lactic acid ??

    • @harrisjoubertwithsleepycre1924
      @harrisjoubertwithsleepycre1924  2 роки тому +2

      I have not looked into lactic acid at all. most of the harsh chemical treatments will kill, or run some bees off. thats one reason I am trying to get away from them. but number one, you have to control Varroa

    • @researcherAmateur
      @researcherAmateur 2 роки тому +2

      Lactic is for keeping the numbers down. Over the spring grow of the hive l use a spray bottle wich sprays very fine (an atomizer). When l inspect the frames l spray not more than 4-5 mils per side with bees and brood on it. It's not a real treatment but does a better job than sublimation every 15 days (how l use the spray bottle) all spring. Since l started with lactic l never had a big varroa drop on the summer treatment after the brood break. So in other words there is never a big number of varroa in my hives. Just don't drown the bees in it.. use it on inspections on the frames you have in hand.. keep the bottle with you and use as you can. I don't know how to explain it better.. It's not a treatment program

    Incidentally saw a few bees walking around right on the top box strip!
    Usual drop 20 average per day for 5 days now 44 then 45 !
    It seems obvious it's definitely more efficient than 2 fumigations of OA.

      I am over the moon with those strips they are just brilliant and not so much hassle as the vape.
      I'm not going to alter the tactics in November either but will give them a break August.
      Is I see any mites drop whatsoever on the tray I'll hit the varmints again with a couple of strips dangled down in the brood frames after the 2 months break. I cannot see for the life of me fuming again when I've seen more efficient results than those fumes.
