Like any treatment, its success depends on colony conditions. Oxalic acid targets mites that are riding on adult bees, but it can’t reach mites sealed under wax-capped brood. For this reason, it works best during periods when your hive is naturally broodless or experiencing a temporary brood break. Ideal times to treat include: Mid-winter, when most colonies are broodless After capturing a swarm Following a natural swarm and requeening event During a brood break (natural or induced) These windows give oxalic acid vapor a clear path to nearly every mite in the colony, making treatment far more effective and helping your bees thrive.
