    I have an outbreak of soft scale parasite on my best orchid!
    It crossed over from another orchid, onto a spiny leaf Zamioculcas and then onto this one. It's causing a 'honey bloom' on the leaves.

    I'd like to treat it with a spray, but I know that orchid's are sensitive, so I wanted to check if anybody had a specific pest killer I should use.

    Thanks for any assistance!

    not all that familar with such a specialty topic as orchids but i do know that they are very sensitive and caution should be the order of the day when spraying, one popular but time consuming treatment is the dab method, using isopropyl alcohol and a q-tip to spot treat the parasite,this is slow work but quite accurate, you can pick off any scale by hand as most any spray treatment won't penetrate the scales. another thing to consider if infestation is bad would be to re-pot the affected plants as the compost can harbour eggs and juveniles....whatever course of treatment you decide on will have to be repeated 3 or more times to deal with the differing stages of the life cylce.
