Mites infiltrate the hive and start feeding on grownup bees, spreading viruses and weakening the bees. Mature feminine mites input bee brood cells and reproduce by way of laying eggs.
Newly hatched mites will feed at the creating bee larva – putting in place a dangerous cycle of in poor health, susceptible bees. Those infestations can escalate, resulting in weakened colonies, compromised immune methods, and devastating colony losses.
In spaces with varroa mites, maximum infested colonies will die withing 2-4 years with out some form of mite remedy plan for the bees.

Chemical Therapies
Analysis has supplied us with a number of chemical remedy choices for varroa regulate. Those merchandise are in most cases divided into two teams: exhausting and comfortable.
The ones regarded as to be exhausting chemical remedies are continuously of man-made starting place. They boast nice efficacy yet can also be exhausting at the colony and/or have a better chance of chemical buildup within the beeswax or honey.
Arduous Chemical substances
Please remember that simply because those varroa remedies fall into the exhausting class – that doesn’t imply you must keep away from them.
They have got been examined and authorized as a result of they paintings with supposedly little chance to the bees or people.
Additionally, varroa resistance to a few of these merchandise is reported within the business. If you select to make use of those merchandise, it is very important rotate them.
You should use your personal judgement when deciding what to place for your hive – weigh the risks-rewards.
Apistan (fluvalinate)
Apistan (fluvalinate) is an older substance used for mite regulate in honey bees for years. It’s an impregnated strip that kills by way of touch. Strips should be positioned within the hive after which got rid of after a undeniable time frame.
Experiences of broad unfold resistance to fluvalinate has been reported in colonies over contemporary years. Additionally, chemical residues would possibly persist in beeswax within the hive. Maximum beekeepers that I do know now not use it.
Checkmite+ (coumaphos)
Offered as Checkmite+ – coumaphos is any other product that has been used for varroa regulate and coincidently additionally aids in controlling Small Hive Beetles.
As nice as that sounds, there are severe issues throughout the business in regards to the unwanted effects within the hive.
I’ve by no means used this product. Offered as a limited pesticide in some spaces – chances are you’ll desire a veterinarian approval to buy.
Apivar (amitraz)
Apivar (amitraz) is an artificial miticide that kills by way of touch. Impregnated strips are positioned close to the brood nest similar to Apistan. This chemical was once used for mite regulate for some time up to now, then pulled and now allowed once more.
Apivar has time utilization restriction. Don’t position honey supers in your colony for no less than 2 weeks after remedy.
Low ranges of residue can also be detected within the beeswax and honey. Mites can broaden resistance. However, some beekeepers record excellent effects with this authorized varroa mite remedy product.
Comfortable Chemical substances
Comfortable chemical substances are the ones remedies which might be derived from herbal elements. They paintings with out leaving noticeable residues within the wax or honey. Sadly, they don’t seem to be the short and simple repair that arduous chemical substances promise.
They don’t seem to be as efficient in mite removing and also you should track the colony to verify they labored. With comfortable chemical mite remedies – you’ll’t merely installed a strip and overlook it.
There also are a number of very important oil recipes for bees that you’ll make and check out for your hives. Many beekeepers really feel that very important oils advertise excellent well being in honey bee colonies. However, use care – some very important oils are absorbed throughout the pores and skin. Put on gloves.
Don’t assume that those remedies are susceptible – many of those herbal compounds are sturdy and must be used with care.
Formic Acid
Mite Away Fast Strips (MAQS) formic acid (biological acid) works as a fumigant. Biodegradable remedy pads are positioned within the hive for 7 days.
After 7 days, you’ll take away the pads or now not. A plus, you’ll use Mite Away Fast Strips when honey assortment supers are at the hive.
Formic Acid additionally kills mites in capped brood (many others don’t). That is an biological remedy yet it is usually sturdy – particularly if the temperatures are very hot.
Some beekeepers have reported queen loss or a discount in brood manufacturing. I by no means had any issues whilst the usage of this product. However, I at all times observe the instructions at the label!
Excessive temperatures above 92° F all over the remedy software would possibly reason colony absconding. In my area, the temperature necessities for a few of these remedies have been a large drawback.
Formic Professional is an alternative choice for the ones in need of to make use of formic acid. This model has an extended expiration date for the package deal in case you wish to have to stay some readily available.
It really works in the similar manner as MAQS with one of the crucial similar advantages and demanding situations. I periodically use formic acid remedies in my colonies, they’re very efficient.
Thymol Merchandise
Crucial oils are herbal compounds distilled from vegetation. One of the crucial well-liked very important oils used for mite remedies is thymol.
There are a number of thymol merchandise available on the market. They do a excellent task of varroa regulate in beehives. However, they should be utilized in a selected temperature vary.
How neatly thymol merchandise paintings depends upon colony power and climate prerequisites. Additionally, test after the remedy length to make sure luck.
Apiquard
Apiguard is a gel containing thymol that acts as a fumigant to kill mites. Like lots of the herbal remedies, this product is temperature delicate.
Temperatures must be between 59° F and under 105° F. (In my view, I would wish it to be a lot cooler in my humid local weather ahead of I used it in my hives.) Use two times at 2-week periods to finish a mite regulate plan.
Api Existence VAR
CONFUSION ALERT: There’s a distinction between Apivar and Api Existence V A R. One is an artificial chemical and one is a softer very important oil based totally remedy. Each are authorized to be used in beehives.
Api Existence Var (thymol, eucalyptol oil, menthol, camphor) Api Existence VAR is any other contender for the some of the highest varroa mite remedies.
The product includes a inexperienced spongy pad impregnated with oils and works as a fumigant. Remedy comes to placement of pads at the most sensible bars of the hive – thrice at 7 day periods. An appropriate temperature vary is between 65-85° F.
Very prime temperatures all over the remedy length could cause severe colony disruption together with bees leaving the hive or absconding.
Oxalic Acid
Utilized in Europe for years, beekeepers in the USA can now use oxalic acid as a varroa mite remedy. Oxalic acid (Oxalic acid dihydrate-organic acid) is utilized in two techniques for mite regulate – as a drizzle or as a fumigant (vaporization).
Drizzle
The drip or drizzle manner comes to blending OA with sugar water and pouring this over the cluster of bees.
The drizzle manner is highest utilized in early Iciness or past due Fall-when the bees are clustered in combination. The colony must have very little brood so nearly all of mites will likely be at the grownup bees.
The annual restrict of drizzle packages is two in step with yr. It is because the acid is rather corrosive to bee our bodies. Don’t use drizzle remedies in excessive chilly or the bee cluster can turn into chilled.
Vaporization
Oxalic Acid Vaporization – A small quantity of OA crystals are put on a unique wand and slid into the hive. The wand heats inflicting the crystals to vaporize.
Because the vapor cools, crystals reform within the hive. Honey bees take away the acid crystals and disclose varroa to the substance.
Oxalic acid vaporization is an overly impact varroa mite remedy all over Fall and Winter – instances when much less brood is within the hive. It does now not kill mites hidden within the brood cellular.
You want to make or acquire an oxalic acid vaporizers. Watch out when buying a wand. You need one who works correctly, you do NOT need to be breathing in any fumes. Put on suitable protection masks and many others. Practice the producers instructions – learn the label.
The usage of OA within the Summer season
Vaporization is my present manner of mite regulate. I imagine it’s the highest varroa mite remedy for bees in my space.
We’ve got a large number of scorching climate That makes one of the crucial different herbal or biological varroa mite remedies flawed all over July/August. That is the time that I want to have a wholesome hive – on the point of lift wholesome fats bees for Iciness.
As a result of this technique does now not kill mites hidden within the brood cellular, the southern beekeepers I do know – repeat this remedy each 5-7 days for thrice. Thereby, masking an entire employee bee brood cycle.
However, some researchers really feel the regulate isn’t excellent sufficient. That even the usage of more than one remedies over a length does now not cut back the mite load sufficient. I don’t argue that time – yet for me, it’s the most efficient factor I’ve at this time.
Fogging with Oxalic Acid- Will have to you?
You’re going to listen a large number of data on the web and YouTube about fogging with Oxalic Acid. We people are at all times in search of an more uncomplicated approach to do issues. No hurt in that -but chances are you’ll hurt your self or your bees.
Fogging with OA isn’t authorized in the United States (right now). I’ve now not observed any authorized analysis experiences that say this is a excellent thought. I can now not use this technique for the prevailing.
HopGuard (Potassium salt -hops beta acids)
Potassium salt of hop beta acids (16%) is a herbal product made out of hop compounds. It’s protected to make use of any time of yr – even if honey supers at the hive.
It’s simpler when there’s much less brood within the hive because it does now not kill mites below the cap (the place nearly all of them are).
Beekeepers record that it’s messy to paintings with. Additionally, beekeepers in my area have now not reported constantly excellent effects the usage of Hopguard. Nonetheless, chances are you’ll make a decision to present it a check out in your apiary.
IPM (Built-in Pest Control) Approaches
Chemical substances don’t seem to be the one approach to struggle varroa. In an built-in pest control plan (IPM) beekeepers use all struggle the mite.
A method beekeepers handle mites is using mechanical strategies. The usage of screened backside forums (as a substitute of cast), reasons some mites to fall to the bottom and perish.
There was once prime hopes for using screened backside forums (also referred to as IPM forums) to start with yet I’ve little self belief in them at this level as a varroa regulate. The collection of mites got rid of is simply too insignificant.
Then again, screened backside forums are nice at giving your hive further air flow and I feel they’re definitely worth the effort in that appreciate.
Powdered Sugar Use
A number of years in the past, using powdered sugar turn into a well-liked remedy plan for varroa. Beekeepers would take a cup of powdered sugar and use a sifter to mud the bees.
Casting off the hive most sensible and dusting the highest bars as bees got here up from under. The theory was once that because the bees groomed themselves to take away the sugar – extra of the mites could be knock off.
Sadly, this technique has confirmed to be very useless. t does now not lead to a important relief in mite populations (a lot the similar as using a screened backside board).
Few beekeepers hassle to make use of powdered sugar dusting these days. However, I should admit that the white bees gave the impression of little flying ghosts for some time – moderately lovable.
Drone Brood Elimination
Some beekeepers advise the removing of creating capped drone bees (the mites favourite host). They use particular drone frames to inspire drone manufacturing. As soon as full of capped brood and creating mites within, the body is got rid of.
Freeze the entire body, killing the mites and the drone brood is sacrificed as neatly. After thawing, the body is put again into the hive for reuse.
In my view, I’m really not keen on this technique. You should take note to take away the body at the right kind time. Another way, you might have simply created a mite maternity ward.
