Natural Varroa Mite Control for the World’s Beekeepers
The Varroa mite is the #1 threat
to bee health.
The Varroa mite:
❐ Reduces hive health, increases
susceptibility to other bee diseases.
❐ Transmits disease from bee to
bee…hive to hive.
❐ Reduces winter survivability.
❐ Has developed resistance to many
existing control agents.
HopGuard®II is a highly effective, natural Varroa control system.
HopGuard®, a proven miticide derived from hop compounds,
provides the beekeeper with a natural, safe and easy to use
alternative to traditional harsh chemical control agents.
❐ Promotes bee health and survivability naturally.
❐ Safe for the bee, the beekeeper, and the environment.
❐ Easy to use.
HopGuard® II Properties.
❐ Natural, food grade product.
❐ No negative effects on normal hive activity.
❐ Bee, Brood, and Queen tolerance...no negative effects
on egg laying.
❐ No residual in honey.
❐ Typically only one application is required.
How to use HopGuard® II.
❐ HopGuard® II should be added to all hives at the rate of
2 insert strips per 10 frames…strips must be hung between
frames.
❐ HopGuard® II can be used throughout the year. For best
results, leave strips in the hive for a minimum of 14 days.

Natural Varroa Mite Control for the World’s Beekeepers
Field Trials of HopGuard® II Functionality
Fig. 1 – Efﬁcacy of HopGuard® II after 2 weeks - Fall 2013
In Arizona, heavily infested standard 10
frame hives (single and double stacked)
were treated with HopGuard® II. Mite
load was reduced significantly with 1
treatment, normal colony behavior was
observed, no change in bee mortality
was noted, and no residuals were found
in honey.

In Saskatchewan, single brood chamber
bee colonies treated with HopGuard® II
achieved similar results to the Arizona trials
and to the trial’s 3 consecutive applications
of traditional HopGuard. Normal colony
behavior was observed and hive health was
maintained.

In Alberta, HopGuard®II was evaluated
in heavily infested double-brood
chamber bee colonies. A single
application of HopGuard® II provided
excellent Varroa control. Normal colony
behavior was observed and hive health
was maintained.
