Commercial Varroa Control for Serious Operators

If you’re running dozens or hundreds of hives, varroa treatment isn’t a once-a-season afterthought — it’s a critical, recurring, expensive part of your operation. Buying small retail packs for every treatment cycle is inefficient and expensive. The Bayvarol® Strips Pack of 800 is the commercial bulk solution: one purchase covers treating 200 hives of a globally trusted, APVMA-permitted varroa miticide — the same proven product used by serious commercial beekeepers worldwide.

Bayvarol delivers reliable, effective varroa control via flumethrin — a synthetic pyrethroid that’s genuinely valuable to have in your IPM (Integrated Pest Management) rotation. Manufactured by Bayer, APVMA-permitted under PER95037, and delivered in strips that hang between brood frames for slow-release treatment. Used in rotation with oxalic acid (Api-Bioxal) and amitraz (Apivar/Apitraz), it forms the third critical chemical class needed to prevent varroa resistance and keep your colonies protected long-term.

Why Buy the 800-Pack Instead of Smaller Packs?

Pure economics. The 800-pack delivers significantly better per-strip pricing than smaller retail packs — just as bulk pricing is cheaper. For commercial beekeepers treating 50, 100, or 200+ hives twice a year, the per-strip savings add up to hundreds or thousands of dollars per season. The 800-pack covers 200 hives at 4 strips per hive — enough for one complete treatment cycle of a sizeable commercial operation, or two cycles of a 100-hive sideliner. If you’re treating fewer hives, our smaller pack sizes may suit you better; for serious commercial work, the 800-pack is the right choice.

What Makes Bayvarol Effective?

The active ingredient is flumethrin, a synthetic pyrethroid that’s highly toxic to varroa mites but safe for honey bees when used as directed. Each strip releases the active ingredient gradually over 6 to 10 weeks, giving complete brood cycle coverage — critical because varroa mites spend much of their lives hidden inside capped brood cells where short-burst treatments can’t reach them. As bees walk over the strips, they pick up traces of flumethrin and distribute it throughout the colony via grooming and trophallaxis. Mites that encounter the active ingredient die; new mites emerging from brood cells encounter it too. Result: typically 90%+ varroa knockdown per treatment cycle.

How Do I Apply Bayvarol Strips?

Bayvarol is applied as a slow-release in-hive treatment:

  • Step 1 — Remove honey supers: Bayvarol has a mandatory honey withholding period; pull all honey supers before treating
  • Step 2 — Hang the strips: insert 4 strips per brood box, between brood frames where bee traffic is highest
  • Step 3 — Leave in place: 6 to 10 weeks (covering a complete brood cycle)
  • Step 4 — Remove and dispose: remove the strips after the treatment window and dispose according to APVMA guidelines
  • Step 5 — Wait before honey production resumes: follow APVMA honey withholding periods before placing supers back.

Why Rotate Bayvarol With Other Treatments?

Resistance is the biggest threat to long-term varroa control. Using only one chemical class repeatedly allows mites to develop tolerance, which is exactly what’s happened in some overseas markets where pyrethroid-only treatment failed within a decade. A proper IPM rotation strategy uses three or four chemical classes in different cycles, preventing any single class from being overused. A strong Australian IPM rotation includes:

  • Pyrethroids: Bayvarol (flumethrin) — this product
  • Amitraz: Apivar / Apitraz
  • Organic acids: Api-Bioxal Powder or Liquid (oxalic acid)
  • Optional fourth class: formic acid products, where available

When Should I Treat With Bayvarol?

The ideal treatment windows for Bayvarol mirror most in-hive miticides:

  • Late summer / early autumn: treat after the main honey flow, before winter, when mite populations have built up over the season
  • Early spring: treat before honey supers go on, knocking back any mites that survived winter and before brood production peaks
  • Between honey flows: Bayvarol’s 6–10 week treatment window means it sits comfortably between Australian seasonal flows.

Always monitor mite levels first using sugar shake, alcohol wash, or sticky-board counts. Treat when counts exceed your IPM threshold — unnecessary treatment wastes product, accelerates resistance, and risks contaminating honey if timing slips.

Does It Require Honey Withholding?

Yes — this is the critical difference between Bayvarol and organic-acid treatments like Api-Bioxal (which has no withholding). Bayvarol requires removing honey supers before treatment and a withholding period before honey production resumes, per the APVMA permit conditions. Always check the current label and APVMA permit for exact requirements. This is why treatment timing is critical — plan Bayvarol treatments for between honey flows, giving the strips time to do their work before supers go back on for the next production cycle.

What Safety Precautions Should I Follow?

Bayvarol contains a synthetic pyrethroid and requires sensible handling:

  • Wear chemical-resistant gloves when handling and inserting strips
  • Avoid skin contact with the strips themselves — wash immediately if it happens
  • Wash your hands thoroughly after handling strips, before eating or drinking
  • Store in original sealed container in a cool, dry place — keep away from children, pets, and food
  • Dispose of used strips according to APVMA guidelines — do not place in regular household waste
  • Do NOT use simultaneously with other in-hive miticides — rotation requires distinct treatment cycles

Do I Need to Keep Treatment Records?

Yes — APVMA Permit PER95037 requires record-keeping for a minimum of 2 years. Records must include:

  • Date of treatment
  • Location and identification of hives treated
  • Quantity of product used (number of strips)
  • Date strips were removed from hives
  • Names and addresses of persons performing treatment — records must be available for APVMA or state department inspection on request

Who Is This 800-Pack For?

This commercial bulk pack is built specifically for serious beekeepers managing large numbers of hives. It’s especially valuable for commercial beekeepers running 100+ hives needing efficient bulk treatment, large sideliners managing 30–100 hives through one or two treatment seasons, queen breeders maintaining multiple breeder and mating colonies, migratory beekeepers needing varroa control during pollination contracts, and beekeeping co-operatives pooling treatment purchases across multiple members. If you’re a hobbyist with 1–10 hives, see our smaller Bayvarol pack sizes instead.

“AROMATHERAPY” IN THE SHOWER
LOVE this scent! Strong in shower but mellows once rinsed off (might be too strong for sensitive individuals). It’s an “aromatherapy” experience every time you shower! We like the scent so much we put a squirt or two in our foaming hand soap dispensers (we switched to fragrance free hand soap so we could scent it with this)!

The best hand soap bars PERIOD.
Size: 3.5 Ounce (Pack of 3), Size: 3.5 Ounce (Pack of 3)
Wow! I am actually VERYYYY impressed with this soap. Believe me when I tell you I have tried everything from $5 for 6 bars soap to $50 for 1 bar soap (not an exaggeration). And I can wholeheartedly say this is the absolute best bang for your buck when it comes hand washing/soap. To me these little bars are absolutely awesome for hand washing. I use the scrubby bar when I have a ton of grease after eating say pizza or something & and then I use the moisturizing bars for all other hand washing. These bars blow away some of the best artisan expensive bars I’ve used like Caldwell Massey or Gentleman’s Nod or Ariana & Evans. These are now go to hand soap bars and I will use nothing else because these are so good. I don’t use liquid soap because I feel like I can never get it off and it feels like it’s always still stuck to my skin even after rinsing and rinsing and rinsing so I like using bar soap and I like bar soap that really dry out your skin for your hands and these little bars do it extremely well without over drying your skin. I do wish the scent was a bit more powerful because all 3 bars have a nice scent each. Tried the sandalwood bar in the shower and like I suspected go with the 6oz bars for the shower because these little 3.5oz guys just go too quickly for all over body use. So for the shower, I’ll use the 5.3/6oz bars and my hands these little guys will now be my go to!

Great Quality Soap with a Clean, Masculine Scent
Size: 3.5 Ounce (Pack of 3), Size: 3.5 Ounce (Pack of 3)
I recently got the Rinse & Robust Men’s Bar Soap Set, and the bar I’m holding in the picture is the Leather scent, which my husband has been trying out first. It has a rich, masculine fragrance that smells clean without being too strong. The soap lathers nicely, rinses off easily, and leaves his skin feeling soft instead of dry. The set also includes Sandalwood and Teakwood, which both smell amazing in the box. I can already tell they’ll be just as refreshing. Each bar feels well-made and lasts longer than most store-bought soaps we’ve tried. The packaging looks great too, so it would make a thoughtful gift set. So far, the Leather scent has been a hit. It’s a classic, smooth, and perfect for everyday use.
