For anti-varroa treatment, it would be nice to have ability to mark last time a colony was treated

• set which treatment was used
• set when next treatment is needed
• tied to Alerts to remind of something

Treatment:

• thymol / apiguard
• thymol + oil eucalyptus + menthol (api life var).
• formic acid (for-mite, mite-away quick strips, formic pro)
• hop beta acid resins (hopguard 2/3) - brood chamber, 14 days, max 30 days. Up to 4 times per day
• oxalic acid (oxalic acid dihydrate) = toxic to humans. vapourizer device or as a solution. little or no brood.
• sucrose octanoate (avachem sucrose octanoate). interval of 7 days x 3 times per infestation. Spray.
