One thing I want to say if you have Saskatraz bees. Synthetic Chemical compounds should not be used for treating Saskatraz bees. Synthetic Chemical compounds would be ApiVar, Checkmite, Apistan.
The synthetic miticides while initially lowering the mite populations, may in the future, lessen the Saskatraz bees ability to cope with new mite infestations. In other words if you have Saskatraz bees Formic Acid may be your best mite treatment option. Having said that here are some other mite treatment options, pro and cons.
Formic Acid, organic, ingredient formic acid, fumigant
- Pro, organic treatment, will not leave deposits in the wax, inexpensive, unused strips store well for a year, short treatment window 14 days, good mite efficacy, supers can be on, 2 hive, 10 hive or 25 hive treatment packs
- Con: Temperature dependent, has a temperature window to work properly, may injure some open brood, a fragile queen may be killed, especially when treating at the upper temperature limits.
ApiVar: synthetic miticide, ingredient, Amitraz, direct contact strip
- Pro: works well on Italians and Carniolans, easy to apply plastic strips, Works at all temperatures,
- Con: expensive, 42 day treatment, may leave wax residue, some resistance being reported, strips have to be in contact with the bee cluster to work, supers must be off, unused strips do not store well, 10 strip or 50 strip package. 2 strips used per deep of bees, up to 4 strips needed per hive treatment
ApiGuard: ingredient Thymol gel, fumigant
- Pro: works well, easy to apply tins
- Con: 30 day treatment, two tins 15 days apart, temperature dependent, a 3/4" shim need to be used for bee space for bee access, supers must be off, needs to be applied in the upper Midwest by no later than mid August because if it cools off in September it may not be effective. Need to purchase 10 tins (five hive treatments)
Checkmite and Apistan have shown mite resistance to these products
