Sugar Shake Month is held every April. The annual campaign is a joint initiative between NSW DPI, the Amateur Beekeepers Association NSW and the NSW Apiarists' Association.

During April beekeepers are encouraged to inspect their hives for exotic pests like varroa mite. Exotic bee pests are not present in Australia but have the capacity to devastate our honey bee industry if allowed to establish.

The best way to inspect for varroa and other exotic mites is to carry out a sugar shake test. During April sugar shake your bees and the let us know the results of your test.

Inspect your hives in April

Sugar shake your bees

Hives can be inspected using the sugar shake test. This method relies on the sugar particles separating the mites from the bee. This technique does not kill the bees.

Sugar shake kits can be purchased from beekeeping supply stores, or you can make your own.

Report your results to NSW DPI

Submit sugar shake results

Early reporting of an exotic bee pest like varroa as is one of the most important factors in eradicating any incursion. Negative test results are also important in proving that Australia remains free of pests like varroa mite.

Sugar shake test results will be used to support Australia’s export trade of queen and packaged bees.

If you think you have found an exotic pest like varroa mite, you must notify NSW DPI immediately. You can report suspected exotic pests by calling the Exotic Plant Pest Hotline 1800 084 881

Code of Practice requirements

From 1 July 2020, it is a requirement for all registered beekeepers in NSW to conduct at least 2 hive inspections per year for the presence of exotic bee pests including mites. Sugar Shake Month is a perfect opportunity to fulfil part of your obligation to comply with the Code.

Exotic pest mites

Varroa mites

Varroa mites (Varroa destructor and V. jacobsoni) infest honey bees (Apis mellifera) in every major beekeeping area of the world, except Australia. The mites are tiny reddish brown external parasites of honey bees. They mainly feed and reproduce on larvae and pupae in the brood. Mites also feed off adult bees, transmitting viruses, weakening the colony and resulting in death of the hive.

Braula fly

Braula fly or bee lice (Braula coeca) live in honeybee colonies. The larval stage burrows under the cappings of honey comb, reducing its commercial value. Brauly fly is present in Tasmania and has not been detected on mainland Australia.

Tropilaelaps mite

The tropilaelaps mite (Tropilaelaps clareae and T. mercedesae) is a parasite of honey bees. They are reddish in colour and about half the size of varroa mites. They mostly reproduce in the brood but some are found on adult bees. Symptoms include deformed pupae and adults (stunting, damaged wings/legs/ abdomens) and colony decline.
