Debugging dormant bulb pots?

Greetings,

  I don't think either aphids or spider mites can "hide" in soil (unlike mealy bugs which frequently can be subterranean).

  The problem is that aphids have winged adult forms and spider mites can float on the wind like dust. Even wingless aphids can be carried into your greenhouse by the ants who farm them. So you can only reliably exclude them from entering your greenhouse if it is hermetically sealed and you undergo decontamination prior to every entry.

  The greenhouse can act as a partial barrier, of course - but you should not rely on it to prevent infestation altogether. You'll still need to be vigilant and to utilize your preferred bio-control methods from time to time when pests re-establish themselves.

Subject: [pbs] Debugging dormant bulb pots?

Hello list-ers,

I will be bringing my dormant bulb pots from the garage into the
newly-cleaned greenhouse soon.  I have had problems with pests (aphids,
spider mites) in the greenhouse in the past.  Does anybody know if
either of these pests (or others) can hide in the soil in the plant pots
of these dormant bulbs?  They are mostly South African bulbs of  various
sorts in very free draining/sandy/gravelly mixes.  If the pests can hide
in the soil, is there a way to get rid of them before bringing the pots
back into the greenhouse?

best regards

Sarah
