Tracheal mite can be a real killer, especially in the
North. A study done at the University of Guelph,
Ontario, by a grad student found that once the
temperature in the hive around the cluter dropped
below 4C the bees with tracheal mites couldn't get
enough oxygen.
Good winter packing makes a difference and a proper
formic acid treatment (Mite-AwayII)once a year really
cleans it up.
