It is becoming clearer from this list that experience depends on whether u
keep bees close to other beekeepers and feral colonies or are isolated. In
my area, monitoring of all hives shows that one single hive can suddenly
leap in Varooa, due I imagine to robbing an infested colony. If missed,
that colony then spreads the mite. Regular treatment with a suppressant
such as thymol cannot cope with a sudden surge. Move your bees u may say.
Unfortuneately, this is a good area for forage which is why the other bees
are here. I suspect this random sudden rise in infestation level in single
colonies may be common - but does anyone else think so?
